Restoring an inherited value for a child profile?
by Zack Perry 16 Aug '13

16 Aug '13

I have a profile that is created using the command: cobbler profile add --name=... --parent=... The child profile's 'Template Files' attribute originally inherited from its parent. For testing, I changed it using cobbler profile edit --name=... Once I was done, I thought that the defaults in the parent profile were sufficient, so I wanted to restore the <<inherit>> value. But, neither cobbler profile edit --help nor man cobbler offer any hints how to do so. I tried the cobbler web UI as a last resort, no dice either. Yeah, I can cobbler profile remove --name=... to delete the modified child profile and then recreate it. It's not that hard, but conceptually it's uneconomical :-( So the Q: is it possible to restore an inherited value for a profile attribute? If so, what is the correct work flow? Regards, --Zack

Re: [cobbler] cobbler 2.4.0 and problems booting Ubuntu 12.10 desktop 64bit

Hi James and Andrew, Thanks for your two's follow-up. Looks like it's probably a good idea to file a bug report upstream to Ubuntu to Debian's Installation Team? Personally, I think what Ubuntu has done qualifies as a "bug". > I played around with the 12.10 images today.

I still have a couple of ideas to try out before we give up on Ubuntu 12.10 and later completely. I have a couple of other ideas to try out. Will report back to the list.

Project Status and Direction
by James Cammarata 05 Dec '12

05 Dec '12

Hey all, just wanted to send out a quick update on the project status. The release24 branch has been receiving patches, and is alpha quality. I'm looking for more users to check it out and give it a test. One of the biggest holdups to this release is the documentation. The 2.2.3 manual will need to be forked and updated with all of the new features in 2.4.0, such as: * Dynamic settings - no more needing to restart cobblerd when changing settings. * Better debian/ubuntu support (better preseed, more snippet support, etc.) * Support for bonded bridge interfaces (useful for virtual hosts) * OpenVZ support as a virtualization type * Web GUI improvements * Alpha support for MySQL as an alternate storage backend And probably a few more that I'm forgetting. So, if you're familiar with any of these features, take a look at the docs repo - any help updating the docs would be appreciated. Right now, a lot of the pages content was essentially just copied from the wiki, so there is a lot of cleanup left to do. Once the manual is forked, we're going to have to do that in two places, so it'll be easier to tackle now before we fork it. There are two primary goals on my road map right now: 1. Work towards adding support for IaaS platforms like OpenStack, Eucalyptus, etc. 2. Improve unit testing and continuous integration testing with Jenkins. Both of these goals require some dedicated hardware, so to help fund those goals I have created an Indiegogo campaign: http://www.indiegogo.com/cobbler24 This will be the only time I mention this on the mailing list, but I will put it up on the project home page and mention it via twitter. So any help in getting the word out will of course be greatly appreciated. Overall, I think the project has been moving in a positive direction, and the last 6 months have flown by since taking over as maintainer. Any comments or other feedback are always welcome. Thanks!

AFAIK, the ubuntu-12.10-desktop-amd64.iso and ubuntu-12.10-server-amd64.iso do not provide working netboot images for PXE network install. Please see my test report in this regard: http://www.mail-archive.com/cobbler@lists.fedorahosted.org/msg08210.html As a result of my digging around, I found lubuntu-12.10-alternate-amd64.iso (never tried it before).

I even tried to replace the Packages.gz in universe/debian-installer/binary-amd64 with the result of dpkg-scanpackages, gzipped, but the graphical login is still missing after the install.

RFC: adding a cobbler debmirror.template?
by Zack Perry 30 Nov '12

30 Nov '12

As of now, cobbler has the following etc templates <https://github.com/cobbler/cobbler/tree/master/templates/etc>: dhcp.template dnsmasq.template named.template rsync.template secondary.template tftpd.template zone.template For those of you who need to deal with Debian/Ubuntu network install, what do you think about adding a debmirror.template to the collection? Rationales: the use of debmirror is no less complex than say dnsmasq, rsync, and definitely more so than tftpd. These three have templates, so why debmirror can't? Motivation: recently Canoncial decided to stop providing a full alternate iso for its default release. There are alternate install isos for other variants, but IMHO the digging and reviewing a collection of disjointed documentation (often are out of date or somewhat inaccurate) is such a waste of time. One of cobbler's main design goal is to mask the complexities of serveral tools typically used for PXE network install. Given what Ubuntu has done, IMHO debmirror becomes an important tool and thus qualifies to have a template. Regards, -- Zack

Cobbler uses DHCP instead of a static IP
by Paul.Goessinger＠dab.com 29 Nov '12

29 Nov '12

Hi, We are using cobber to manage our machines for our satellite. Re are using satellite 5.5 with cobbler 2.0.7. Since our last upgrade, our VMWare Machines do not use the static IP anymore during kickstart. NOTICE NetworkManager: ifcfg-rh: Ignoring connection 'System eth0' and its device due to NM_CONTROLLED/BRIDGE/VLAN. Before the upgrade, this worked. We use this cobbler command to add the machine: cobbler system add --name=thename --profile=theprofilename --hostname=thename --kopts="ksdevice=eth0 umgebung=LAN" --interface=eth0 --static=true --mac=00:50:56:9b:2e:c6 --ip=6.7.8.9 --subnet=255.255.255.0 --gateway=3.4.5.6 --name-servers=1.2.3.4 What are we doing wrong? I searched for different combinations of cobbler, NetworkManager, DHCP etc. but I did not find any usable answer. I hope this is a cobbler problem. Cheers, Paul

This page http://wiki.centos.org/TipsAndTricks/KickStart should be helpful as well. In the Use a specific network interface for kickstart, quoted "A second method is using ksdevice=link. In this case anaconda will use the first interface it finds that has a active link." so you may wish to try that too. HTH -- Zack

cobbler 2.4.0 Ubuntu repository mirroring hostname off-by-one parsing error?

cobbler: 2.4.0 from epel-testing host : SL 6.43 64 bit In http://cobbler.github.com/manuals/2.2.3/4/7_-_Package_Management_and_Mirror… "Also apt" section, there is this example: cobbler repo add --name=foo --mirror=http://url --breed=apt --arch=i386 So far, I have been using either ISO image import or apt-mirror to do direct Ubuntu mirror as debmirror was not available for RHEL for quite some time.

How to enable a graphical install for RHEL desktops?
by Zack Perry 27 Nov '12

27 Nov '12

cobbler: 2.4.0 from epel-testing server : SL 6.3 64 bit Today I attempted to PXE boot the desktop of Fedora 17. According to the Fedora 17 kickstart documentation, the graphical mode should be the default, but the first time, the installer ran in text mode. After the installation was done, I was greeted by just a text console with the login prompt :-( So, I modified the kickstart template such that for desktop installation, it used the 'graphical' option. This worked. Fedora 17 installer ran in graphical mode. The firstboot program launched, and the desktop UI came up. Next, I tried Scientific Linux 6.3 desktop. This time, the same symptom, but using the 'graphical' kickstart option didn't help. Feeling curious, I did the following: [root@cobbler ~]# cobbler system dumpvars --name=nb1|grep text kernel_options : ksdevice=bootif lang= graphical keyboard-configuration/layoutcode=us interface=eth0 text locale=en_US kssendmac priority=critical BTW, the 'graphical' shown in the above line was added by me just for testing. I knew that I didn't set the 'text' kernel option (doubled checked the profile and system objects just to make sure), so I checked the source, indeed: In cobbler/settings.py, there is the following: 78 "kernel_options" : [{"lang":" ", "text":None, "ksdevice":"eth0"},"dict"], Also, in /etc/cobbler/settings, there is the following: [...] # kernel options that should be present in every cobbler installation. # kernel options can also be applied at the distro/profile/system # level. kernel_options: ksdevice: bootif lang: ' ' text: ~ [...] Now, I understand that very few people would use RHEL as desktops. Fedora? Sure. But setting the installation always to text mode seems to contradict with the official RHEL 6 Installation Guide. Is there a way to get the documented behavior, i.e. graphical by default, use text mode when desired? Regards, -- Zack

cobbler-ext-nodes returning nil results for system with mgmt classes and parameters
by Matthew_Luettgen＠aotx.uscourts.gov 26 Nov '12

Greetings, Long time listener (false) first time caller (true.) I am experimenting with Puppet 3.0.1 and Cobbler 2.2.3. I created a test profile, a test sub profile, and a test system in cobbler (via the GUI.) When calling cobbler-ext-nodes hostname, I am getting nil values for both classes and parameters. Some facts have been obfuscated, any values that do not appear valid are likely obfuscated. All files are appears to be parsed by cobbler properly as there are no errors with 'cobbler sync.'

Quick fundraising update
by James Cammarata 22 Nov '12

22 Nov '12

Ok, so I'm breaking my self-imposed rule on this one to share some big news. The support from the community has only been increasing the closer we get to the close of the fundraising campaign, and it never ceases to amaze me. Greg DeKoenigsberg, now the Vice President of Community with Eucalyptus, announced that they would match all contributions up to $2000 to help push us to our target goal! Here's the official announcement on his blog: http://gregdekspeaks.wordpress.com/2012/11/20/shoes-for-the-cobblers-kids/ So a huge amount of thanks to the Eucalyptus team!

build reports no longer get sent after upgrade to 2.2.3

21 Nov '12

Hello, I have upgraded to 2.2.3 from 2.2.1 and after the upgrade no longer receive build report emails as I once did, everything worked prior to the upgrade. I have made sure build_reporting_enabled is set to 1, also ran cobbler sync and restarted the cobblerd service. The server is able to send mail but the fact I don't even see any cobble attempts in maillog concerns me. Any suggestions?? -John

Is it possible to have system object inherits the 'Template Files' value from that of a profile's?
by Zack Perry 21 Nov '12

21 Nov '12

cobbler objects in general follow a very clear OO hierarchy. But the 'Template Files' attributes of profile and system objects seem to be exceptions to such a pattern. If the nodes that use the same profile share the same 'Template Files' attribute, it seems to be more economical to define the value of the attribute once in the shared profile, rather than doing so system by system? Am I missing anything here? Regards, --Zack

cobbler 2.4.0, Fedora 17, eth0 and em1
by Zack Perry 20 Nov '12

20 Nov '12

I finally got around to test cobbler 2.4.0 from epel-testing to PXE boot Fedora 17. After the past few days struggles with Ubuntu, doing RH alike systems is like having a break :-) Nevertheless, I noticed that the system came up with em1. This is not news to me, and I know how to deal with it. But the Q is, up to now, the snippets bundled with cobbler 2.4.0 still assumes that the first network interface is named as eth0. What is the current plan in dealing this device name change (which I know quite a few people are not happy' with)? Regards, --Zack

19 Nov '12

cobbler: 2.4.0 from epel-testing server: SL 6.3 64bit target: Ubuntu 12.04.1 LTS server Out of curiosity, I tried to use the jinja2 for a template file in /srv/cobbler/sources.j2 as follows: #template=jinja2 # # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://us.archive.ubuntu.com/ubuntu/ {{ os_version }} main restricted deb-src http://us.archive.ubuntu.com/ubuntu/ {{ os_version }} main restricted [...] In the system object, I have: Template Files : {'/srv/cobbler/sources.j2': '/etc/apt/sources.list'} The intention is to replace all lines in the /etc/apt/sources.list that have the local repo URL with the official ones. Note, this is done just for experiment. At work, we always use our own repo mirror. But, even with python-jinja2 installed on the cobbler server, I have been getting the following in the installed services.list: # ERROR: JINJA2 NOT AVAILABLE. Maybe you need to install python-jinja2? But, as evident from below, the cobbler host has it!

It provides a Django inspired non-XML syntax but supports inline expressions and an optional sandboxed environment. If you have any exposure to other text-based template languages, such as Smarty or Django, you should feel right at home with Jinja2. It's both designer and developer friendly by sticking to Python's principles and adding functionality useful for templating environments. Is it true that the jinja2 support is only available to snippets? That's my impression from reading /etc/cobbler/settings so far. Regards, -- Zack

Hi James, Thanks for your response. You meant what Jorgen said in http://www.mail-archive.com/cobbler@lists.fedorahosted.org/msg08100.html? quoted "downloading an daily cdrom image and use the kernel/initrd from that."? So far, I have consistent success using cobbler import loop mounted ubuntu-12.04.1-server-x86_64.iso without needing anything from the Ubuntu daily cdrom image site. I will try to PXE boot 12.04.1 alternative CD tomorrow evening. If I succeed again, I will test Fedora and RHEL. Once I am done with these, I will come back to 12.10. > That is a known issue with the x86_64 ISO currently available (date > of 10/17 I believe). I think Jorgen had a workaround that he shared > on the mailing list, beyond that it's broken on Ubuntu's end. Regards, -- Zack

cobbler 2.4.0 and problems booting Ubuntu 12.10 desktop 64bit
by Zack Perry 16 Nov '12

16 Nov '12

I have been testing 2.4.0 from epel-testing. So far, I have been successful in PXE booting Ubuntu-12.04.1-server, 64bit. Since I am off today, so this afternoon I decided to try to PXE boot Ubuntu 12.10 desktop. Setting up cobbler as usual, watching the initrd.gz and linux file retrieved successfully. Now, upon Download installer component, I got a window that displays: "The installer failed to download a file from the mirror. This may be a problem with your network, or with the mirror.

Cobbler 2.4.0 sample.seed not rendering kickstart_done snippet?
by Zack Perry 15 Nov '12

15 Nov '12

I am testing the 2.4.0 from epel-testing using two netbooks, one as the cobbler server running SL 6.3, the other is a test install machine. The distro is Ubuntu 12.04.1 server. A while ago, I again used the /var/lib/cobbler/kickstarts/sample.seed to test out things, and used cobbler system getks --name=nb1 to check out the rendered preseed file. Immediately, I noticed that $SNIPPET('kickstart_done') is not rendered, despite the fact that I have the kickstart defined in the profile, and the system report indicates the following: Kickstart : <<inherit>> The entire kickstart_done snippet seems to be ignored. Is this a known issue, or is there a hint for me to debug it? On our production cobbler server (2.2.3), for RH alike systems, the rendering works fine. Regards, -- Zack

Re: [cobbler] Cobbler 2.4.0, Ubuntu 12.04.1 64bit server == not using local repo?
by Zack Perry 14 Nov '12

14 Nov '12

I need to correct myself: (1) PXE booting Ubuntu does need to use the {linux, initrd.gz} in netboot subdirectory. I finally dug out enough Ubuntu documentation on Ubuntu Web site to confirm what we have learned from trials and errors. (2) Once said pair is used, the three magic variables, $http_server:$http_port and $install_source_directory, work as anticipated. So, James, there is no need to waste your time to double check these. Apologies for the false alarm! On the other hand, I still have a few other issues with my home lab setup (where dnsmasq acts as a proxy, not authoriative DHCP server), e.g.: (a) d-i netcfg/get_hostname string $hostname doesn't take effect. Instead, the randomly assigned device name by 2Wire 3600HGV is used (b) I am still struggling with the use of the last two snippets in the preseed file, i.e. [...] d-i preseed/late_command string chroot /target sh -c ' \ $SNIPPET('download_config_files_deb') $SNIPPET('post_run_deb') '; \ $SNIPPET('kickstart_done') Despite what I set for the 'Template Files' and rendered seed file from cobbler system getks, none of the files got into the installed system. I will simplfy it, do more tests after work, and see if I can find a clue... Regards, -- Zack > That's very odd, these work fine for me when using the master branch > which should not be that divergent from the release24 branch > currently.

Problems with writing systems through the XMLRPC API using perl XML::RPC or XMLRPC::Lite
by Jason Barlow 13 Nov '12

13 Nov '12

I'm trying to create a new system profile using perl through the XMLRPC API. Things work great using python, but when I try to use either of the above perl interfaces, I'm not able to actually write any of the new objects I've created: Reading items works a charm, and it looks like the calls themselves are succeeding, but the host never shows up in a: #[root@spacewalk cobbler]# cobbler system list | grep test # I'm wondering what's going wrong here; am I not authenticating properly? I've tried using both XML::RPC and XMLRPC::Lite, and get similar results, where reads work fine, but nothing actually 'sticks' Here's the script that I'm using for XMLRPC::Lite #!/usr/bin/perl use strict; use warnings; use XMLRPC::Lite; use Data::Dumper; my $username = 'api-user'; my $password = 'sapi-user'; my $proto = 'http://'; my $servername = 'spacewak'; my $api = '/cobbler_api'; my $url = $proto . $servername . $api; my $name = 'vacsld01test'; my $conn = XMLRPC::Lite->proxy('https://vacslp01spacewalk.cucbc.com/cobbler_api'); my $token = $conn->login($username, $password)->result(); my $object = $conn->new_system($token)->result(); $conn->modify_system($object, 'name', $name, $token)->result(); $conn->modify_system($object, 'hostname', $name, $token)->result(); $conn->save_system($object, $token)->result(); $conn->sync($token)->result(); /var/log/cobbler/cobbler.log has: Thu Nov 8 16:03:46 2012 - INFO | authenticate; ['api-user', True] Thu Nov 8 16:03:46 2012 - INFO | REMOTE new_item(system); user(api-user) Thu Nov 8 16:03:46 2012 - DEBUG | authorize; ['api-user', 'new_system', None, None, True] Thu Nov 8 16:03:46 2012 - DEBUG | REMOTE api-user authorization result: True; user(?)

Re: [cobbler] Cobbler 2.4.0, Ubuntu 12.04.1 64bit server == not using local repo?
by Zack Perry 13 Nov '12

13 Nov '12

Hi James, I am guessing that my setup is a very unusual one. I am doing all my testing of the 2.4.0 from epel-testing in my home lab (at work we still run 2.2.3). My home has AT&T Uverse, with a 2Wire 3600HGV router. The router has a built-in DHCP server, which is really awfully limited :-( But, attempting not to be disruptive to my family members, I choose to run dnsmasq 2.63rc3 in proxy mode (the key word is pxe-service. See dnsmasq's man page at http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html The result seems to be that some "magic variables" even take on the values that they should be taking (I know so; as I have a habit of using cobbler system getks --name=... and cobbler system dumpvars --name=...). I have been unable to set static IP address in /etc/network/interfaces and desired hostname in /etc/hostname and /etc/hosts so far. I am trying to fight this intransigence of the silly 2Wire DHCP server via the 'Template Files' attribute of the system object. I should know in about another hour or so. The netbooks that I used for testing are slow like snails :-( But they use very little power... I will let the list of my outcome. Regards, -- Zack ===================================================================== That's very odd, these work fine for me when using the master branch which should not be that divergent from the release24 branch currently. I'm going to be merging the signature branch in with master and release24 soon, and that branch definitely seems to work great with Ubuntu, so I'll double check for this popping up at that time.

Hello, We are trying to install Cobbler (and Cobbler-Web) in a Linus system that is running a SLES 10 SP1. We are tried with source and RPMs, but there is several dependencies that not allow us install cobbler. Anyone here has tried to install cobbler in similar conditions? Thanks.

Cobbler 2.4.0, Ubuntu 12.04.1 64bit server == not using local repo?
by Zack Perry 13 Nov '12

13 Nov '12

This weekend, I decided to try out the cobbler 2.4.0 from the epel-testing. I set it on in my "home lab", on an Acer Aspire One D257 netbook, which runs SL 6.3 64bit. Going over the usual (1) import ubuntu-12.04.1-server-amd64.iso to create a distro and profile, add a repo, reposync, (2) add a system was pretty quick. Since my home has a DSL, so I upgraded dnsmasq from repoforge to 2.63rc6, and used its proxy mode. Two issues immediately became obvious: (1) Ubuntu 12.04.1 LTS default vmlinuz and initrd.gz always resulted prompting for CD/DVD :-( As a quick get-around, I renamed the pair, and copied their counterpart from install/netboot/ubuntu-installer/amd64/. The replacement pair got the PXE going, but despite what I specified in the preseed template, it always retrieve every package from the remote Ubuntu repositories :-( I also tried to use the vmlinux and initrd.lz from Ubuntu 12.04.1 precise desktop daily build. That pair got into the busybox :-( So no go. (2) Despite the fact that I set the desired interface to use during the installation as eth0, I still got prompted for selecting among two (eth0 and wlan0) What I have in the /var/lib/cobbler/kickstart/ubuntu-server.seed: [...] # netcfg will choose an interface that has link if possible. This makes it # skip displaying a list if there is more than one interface. #d-i netcfg/choose_interface select auto d-i netcfg/choose_interface select eth0 [...] # You can choose to install restricted and universe software, or to install # software from the backports repository. # d-i apt-setup/restricted boolean true # d-i apt-setup/universe boolean true # d-i apt-setup/backports boolean true # Uncomment this if you don't want to use a network mirror. d-i apt-setup/use_mirror boolean false # Select which update services to use; define the mirrors to be used. # Values shown below are the normal defaults. d-i apt-setup/services-select multiselect security d-i apt-setup/security_host string security.ubuntu.com d-i apt-setup/security_path string /ubuntu # Additional repositories, local[0-9] available # d-i apt-setup/local0/repository string \ # http://local.server/ubuntu precise main # d-i apt-setup/local0/comment string local server [...] And here is the profile: [root@cobbler kickstarts]# cobbler profile report --name=ubuntu-12.04.1-x86_64 Name : ubuntu-12.04.1-x86_64 TFTP Boot Files : {} Comment : DHCP Tag : default Distribution : ubuntu-12.04.1-x86_64 Enable gPXE? : 0 Enable PXE Menu? : 1 Fetchable Files : {} Kernel Options : {'priority': 'critical', 'locale': 'en_US'} Kernel Options (Post Install) : {'reboot': 'efi'} Kickstart : /var/lib/cobbler/kickstarts/ubuntu-server.seed Kickstart Metadata : {'gateway': '192.168.1.254'} Management Classes : [] Management Parameters : <<inherit>> Name Servers : [] Name Servers Search Path : [] Owners : ['admin'] Parent Profile : Proxy : Red Hat Management Key : <<inherit>> Red Hat Management Server : <<inherit>> Repos : ['ubuntu-12.04.1-x86_64'] [...] The Repos attribute seemed to be completely ignored!

Spurious debugging outputs from koan in provisioning KVM guests
by Zack Perry 10 Nov '12

10 Nov '12

We have been always using a RHEL variant (e.g. CentOS or SL) as the host for KVM guests. I got a spare machine running Ubuntu 12.04LTS so a while ago I decided to use it as a host for a few "disposable" test guests today. Both cobbler and koan are at 2.2.2. The following is what I got: root@teapot:# koan --server=vc0 --virt --system=vc8 --virt-path=/dev/vg/vc8 -w - looking for Cobbler at http://vc0:80/cobbler_api - reading URL: http://192.168.123.3/cblr/svc/op/ks/system/vc8 install_tree: http://192.168.123.3/cblr/links/centos6-x86_64 /bin/sh: 1: rpm: not found .........................................(1)[...] libvir: QEMU error : Domain not found: no domain with matching uuid 'd4e139b9-d2f9-6afc-aff8-7b6db7ace13b' .............................(2) Sat, 10 Nov 2012 09:27:26 DEBUG Could not open "/etc/sysconfig/keyboard" [Errno 2] No such file or directory: '/etc/sysconfig/keyboard' ..........................................(3) Sat, 10 Nov 2012 09:27:26 DEBUG Could not open "/etc/X11/xorg.conf": [Errno 2] No such file or directory: '/etc/X11/xorg.conf' ..........(4) Sat, 10 Nov 2012 09:27:26 DEBUG Could not open "/etc/sysconfig/keyboard" [Errno 2] No such file or directory: '/etc/sysconfig/keyboard'...........................................(5) Sat, 10 Nov 2012 09:27:26 DEBUG Could not open "/etc/X11/xorg.conf": [Errno 2] No such file or directory: '/etc/X11/xorg.conf'...........(6) [...] libvir: QEMU error : Domain not found: no domain with matching name 'vc8' ..............................................................(7) Sat, 10 Nov 2012 09:27:29 DEBUG Started guest, connecting to console if requested Sat, 10 Nov 2012 09:27:29 DEBUG XML fetched from libvirt object: [...] OK. So, the guest vc8 was built and started without a hitch. But IMHO the numbered statements above are confusing. (1) Yes. Even Ubuntu repo provides the rpm utility, but why? (2) If it's a refresh build, then obvious this entry wouldn't exist. So, the statement should be rephrased. (3) For Debian/Ubuntu, the path is /etc/default/keyboard (4) If the host is a server with nearly minimal install, why this file should exist? It shouldn't. (5) & (6), please see above. (7). Please see my comments for (2) above. Comments from others in the list? Regards, -- Zack

How to get virt-install's --cpu host into cobbler/koan?
by Zack Perry 10 Nov '12

10 Nov '12

With the virt-install command, there is this --cpu host option, quoted "Expose the host CPUs configuration to the guest. This enables the guest to take advantage of many of the host CPUs features (better performance), but may cause issues if migrating the guest to a host without an identical CPU." The hardware in our office is quite uniform, so using the option is not an issue. We also must almost exclusively Linux (RHEL, Ubuntu). But I want to use cobbler/koan to do guest provisioning. Nevertheless, having read cobbler --help/man page, and koan --help/man page, I still can't figure out how to set this option in cobbler so that koan can extract it for a KVM guest. Any hints/tips are appreciated. I certainly can do a virsh dumpxml, undefine, edit, define sequence, even scripted. But that just smells so kludgy :-( Regards, -- Zack

Problems in "cobber get-loaders" logic
by Eldred, Doug 07 Nov '12

07 Nov '12

There appear to be two problems in the Cobbler "get-loaders" logic, resulting in failure if you need to use a proxy server: downloading http://dgoodwin.fedorapeople.org/loaders/grub-0.97-x86_64.efi to /var/lib/cobbler/loaders/grub-x86_64.efi Exception occured: <class 'urlgrabber.grabber.URLGrabError'> Exception value: [Errno 14] PYCURL ERROR 7 - "Failed to connect to 2610:28:3090:3001:5054:ff:fedb:7f5a: Network is unreachable" Note the odd connect-to address, there COULD be a third problem here. But for sure: (1) Around line 65 of action_dlcontent.py, if either an HTTP or an FTP proxy is in the environment, we'll try to reference an undefined "var" value (2) The reason this does NOT cause a runtime Python error due to the missing "var" is that the environment is EXTREMELY tiny during execution of this code, and specifically doesn't contain any proxies: os.environ: {'LANG': 'en_US.UTF-8', 'TERM': 'xterm', 'SHLVL': '2', 'PWD': '/', 'PATH': '/sbin:/usr/sbin:/bin:/usr/bin', '_': '/usr/bin/cobblerd'} The terminal session calling "cobbler get-loaders" DOES have the proxies defined, both upper and lower case, and including HTTP, HTTPS, and FTP.

odd repo mirror download path
by Edward Bailey 07 Nov '12

07 Nov '12

I just added a new repo mirror to our cobbler instance and after running cobbler reposync I see that all the rpm packages are under a directory called "repo name"/getPackage instead of under the normal directory defined by the name of the repo. This is the first repo that has this extra directory. Is this expected? Anyway to make it go away? All of our other repos are presented as yum repositories with the same path structure and I would like to avoid have this one repo path be different than the other repos. we are running cobbler-2.0.11-2.el5 Ed

cobbler import and available-as option
by Jason Graham 06 Nov '12

06 Nov '12

Hello, We use Artifactory to manage our artifact repository, including syncing our distro repos from the vendor. Up until now I have been using the import command to import form a mounted vendor DVD on our Cobbler server. What I would like to do it is have it always use our Artifactory server as that will always be available the systems we build. Per documentation the --available-as option should do this for me. Also, from documentation examples it shows that it should work over HTTP. The syntax I am using is... cobbler import --path=http://repo.myserver.com:/artifactory/rhel-6.3-base/x86_64/ --name=rhel6.3 --avaialble-as=http://repo.myserver.com: /artifactory/rhel-6.3-base/x86_64/ The import task fails. The log shows it tried to use rsync. Does it not work over http or am I using the wrong syntax?

Explicitly disable interface
by Mezei Zoltan 06 Nov '12

06 Nov '12

Hi, I've got a machine with 4 interfaces, eth0, eth1, eth2 and eth3. I'm trying to set up eth0-eth1 in bonding for one network, eth3 for another network with some static routes. This works perfectly. However when I first start the machine (with RHEL5 installed) kudzu finds eth2 and configures it to use DHCP. I don't want this to happen, so I'd like cobbler to assign a configuration to the interface with ONBOOT=no. Can it be achieved somehow? (I know that I can add a %post script to my kickstart that generates an ifcfg-eth2 file - but can this setup be achieved by cobbler only?) -- Zizi "...nálatok a cégnél múltból nagyon sok van..."

Hi, Yeah, the home router as DHCP server works. But at work, we use both dnsmasq and ISC DHCP servers (on different subnets), but cobbler manages them. My home router has a Web UI, but it's not as flexible as I would like it to be. I have been searching alternatives, OpenSSH VPN looks promising, but I haven't had the setup to try it yet. Regards, -- Zack [...] I run ESXi 5 and intend to update it to 5.1 which should give me the new web based admin. Not sure if that is part of esxi. I run all my VMs on two networks. A private network interconnect between the machines and a "management" network that allows me to be able to ssh to the boxes that is connected to a network card and my home router which also does the dhcp. My pico cent's worth. Regards

When I do this: # mount -o loop /images/Fedora-17-i386-DVD.iso /distro # cobbler import --name=F17 --path=/distro --arch=i386 task started: 2012-10-22_085223_import task started (id=Media import, time=Mon Oct 22 08:52;23 2012) !!! TASK FAILED !!! # cobbler.log shows that the rsync apparently didn't run because the very next command fails. If I copy the rsync command from the log and run it manually, it works just fine every time, and re-running the cobbler import after the manual rsync runs to completion. What might be causing the rsync within the import command to fail? -- Bret Wortman The Damascus Group Fairfax, VA http://bretwortman.com/ http://twitter.com/BretWortman
