Different gateways for different network interfaces
by Jens Ahrens 23 Apr '09

23 Apr '09

Hi everybody, I want to install a system with 2 NICs. For configuring the systems I did: cobbler system add --name="sys1" [....] --ip="10.0.0.1" --mac="00:01:02:03:04:05" --subnet="255.255.255.0" --gateway="10.0.0.10" cobbler system edit --name="sys1" --interface="1" --ip="192.168.0.1" --mac="00:02:03:04:05:06" --subnet="255.255.255.0" --gateway="192.168.0.10" When I do a: cobbler system dumpvars --name=sys1 I get only one gateway - which is in this case the one for interface 1: 'gateway': '192.168.0.10' In the dumped variables section interfaces, there is no gateway entry. For getting the interfaces configured correctly in my kickstart file I need the correct gateways for each NIC. Is there anything I'm doing wrong? Thanks and cheers, Jens

It's time for another Cobbler survey!
by Michael DeHaan 22 Apr '09

22 Apr '09

Hi Everyone, It's not quite a been a year since the last cobbler survey, but things have been moving exponentially lately, so I figure it's a good time for another! As before, please reply off list (not here, to mdehaan(a)redhat.com instead) and I'll post a anonymized summary of results later. The goal of this survey is understand how everyone is using things, which features get used most, and to better be able to plan and understand where we need to go in the future. It helps me understand what aspects are most important and what other tools are in use along with Cobbler. So, it would be fantastic if absolutely everyone on this list replies -- that would be awesome. Even if you aren't on this list and are reading through gmane, shoot me an email --- it would be greatly appreciated. Results will be shared in a couple of weeks, once I have a chance to aggregate and summarize them. Again, any specifics you wish to share about your deployment help me understand you enormously, I value them, and they won't be shared when I do share the summary. Thanks! --Michael === START == (1) What is your company/installbase and what do you? Be as specific or non-specific as you like, we won't share specifics but want to get an idea of what sectors things are being used in. (2) How did you find about Cobbler and how long have you been using it? (or Just trying it out now, that's good to know also). (3) How many machines do you have managed by Cobbler? (4) Do you use the Cobbler web interface? (5) Do you use the DHCP management feature? (6) Do you use the DNS management feature? (7) Do you use the Power management feature? (8) Do you use "koan --replace-self"? (9) Do you use "cobbler replicate" ? (10) Do you use "cobbler buildiso" ? (11) Do you use cobbler to mirror repositories ("cobbler repo add / cobbler reposync") ? (12) Do you use either the built-in config management tool (--template-files) or the Puppet integration (--mgmt-classes) feature? (13) Do you use koan to install virtual machines? (If so, what Xen or KVM or VMware?) If not, what kind of virtualization do you use? (14) What's the output of the following? You may choose to censor the system counts if you want, but I still would like a feel as to whether system records are well leveraged. sudo cobbler distro report | wc -l sudo cobbler profile report | wc -l sudo cobbler system report | wc -l sudo cobbler image report | wc -l sudo cobbler repo report | wc -l (15) Are you interested in "Cloud" type applications, if so, which? (EC2? Internally hosted?) (16) What Open Source or proprietary software do you use to manage your updates? (yum, Spacewalk/Satellite, etc?) (17) What Open Source or proprietary software do you use for config management (in-house solutions, cfengine, puppet, etc?) (18) What Open Source or proprietary software do you use for monitoring? (19) Just out of curiosity, how interested are you in "ITIL" at your organization and how do you see this affecting Cobbler, if at all? (20) Are the any applications you'd like to see Cobbler integration better with? If so, how? (21) What's your number one requested Cobbler feature? (22) Anything else you'd like to add? === END ===

Adding --template-files text field to webui profile edit page (Trac Ticket #298)
by Bryan Schneiders 22 Apr '09

22 Apr '09

I've attempted to make a patch that adds a text field to the profile edit page in the webui for editing the --template-files list. It successfully shows you the current --template-files list associated with a profile, but it doesn't appear to save changes or additions and I'm not sure why. Patch against 1.6.x branch is attached. -- Bryan Schneiders bschneiders(a)woti.com 301-562-1900 ext 305

Django packaging and RPM update
by Michael DeHaan 22 Apr '09

22 Apr '09

Django files will be installed by the cobbler-web RPM into: /usr/share/cobbler/django Cobbler now has the following three Apache configuration files /etc/httpd/conf.d/cobbler.conf -- basically now just points folks to the web application and also ensures trees are servicable. /etc/httpd/conf.d/cobbler-svc.conf -- handles the mod_python service handlers -- we could actually consolidate this with the first, now would be a good time (I think so, yes?) /etc/httpd/conf.d/cobbler-django.conf (if installed) -- makes http://.../cobbler_web work If the user visits the old URL (http://.../cobbler/web) then they will get a message telling them about the new URL and what package to install.. should help nicely with IRC questions. :) The cobbler web package also stores files in: /var/www/cobbler_webui_content html files, icons, CSS I did this so the path would be wholy owned by cobbler-web, and not by the cobbler package. Makes things a bit less confusing (to me, anyway) The following path no longer has anything in it: /var/www/cobbler/webui Cobbler still puts internal content, but not "web browser content" in /var/www/cobbler as it has always done The following path just contains the index.html file telling folks where the new app is, which we'll keep around for a few releases at least: /var/www/cobbler/web Also in the source tree I've removed "webui_templates" and all the django stuff (mostly) lives in the subdirectory "django-webui". There are still a few source files that we should probably consolidate, noteably django-webui/javascript should go into webui_content (if that makes sense to James) and also the webui.html file that is the minimal online help for the web app should probably move from docs to webui_content too. (Which is not hard). So when folks running 1.6 finally upgrade to 1.8, they should only be slightly suprised by some .rpmsave files they need to remove in /etc/httpd/conf.d -- of which I'm not sure of a great way to save folks from that trouble -- but the web app should nicely point people to the right place once they get going. Comments? Questions? --Michael

Re: [virt] Did you know virbr0 was not a real bridge?
by Mykel Alvis 22 Apr '09

22 Apr '09

Oops. Didn't mean to reply off-list. When I used the technique you described, I get the network alive and kicking but can't seem to get the VMs themselves started. I don't know if it's an issue with koan starting the vm or with my libvirtd dnsmasq config. I can't seem to see if the koan process is working correctly because the console output from virt-manager is a blank screen. When I use virsh to connect and try to reach the console, it hangs uninterruptedly. Do you (or anyone) know if this is because the network is still awry or if it is likely to be something else?

missing file icon_16_sync.png?

22 Apr '09

I see /var/log/http/error.log complaining about missing file icon_16_sync.png. It is referenced in styles.css I checked in cobbler-1.6.3-2 on fedora 10. Nothing important - just annoyance. Thanks, Leon

[virt] Did you know virbr0 was not a real bridge?
by Michael DeHaan 22 Apr '09

22 Apr '09

virbr0 as created by libvirt is a private network, it's not a real bridge. If you want your guests to be reachable, you need to create a real bridge on your virtual hosts and use that as the --virt-bridge in Cobbler. Instructions are here: https://fedorahosted.org/cobbler/wiki/VirtNetworkingSetupForUseWithKoan Making a snippet that automatically makes a bridge for the first interface seems like a nice thing to do (or finding some way to do this with interface objects). --Michael

repo is not defined error
by Nicholas Schuetz 21 Apr '09

21 Apr '09

Hello, I am getting the following error when I try to add two repos to a profile. I can save the profile with an individual repo defined though. When more than one is defined I get this error: --- 2009-04-21 12:40:13,013 - api - Exception occured: cobbler.cexceptions.CX 2009-04-21 12:40:13,013 - api - Exception value: "repo ['RHEL-5-i386-TEST', 'RHEL-5-i386-THIRDPARTY'] is not defined" 2009-04-21 12:40:13,014 - api - Exception Info: File "/usr/lib/python2.4/site-packages/cobbler/remote.py", line 1567, in _dispatch return method_handle(*params) File "/usr/lib/python2.4/site-packages/cobbler/remote.py", line 1392, in modify_profile return self.__call_method(obj, attribute, arg) File "/usr/lib/python2.4/site-packages/cobbler/remote.py", line 1374, in __call_method return method(arg) File "/usr/lib/python2.4/site-packages/cobbler/item_profile.py", line 253, in set_repos return utils.set_repos(self,repos,bypass_check) File "/usr/lib/python2.4/site-packages/cobbler/utils.py", line 1123, in set_repos raise CX(_("repo %s is not defined") % r) --- I see both repos in the repo list: # cobbler repo list RHEL-5-i386-INTEG RHEL-5-i386-PROD RHEL-5-i386-TEST RHEL-5-i386-UAT RHEL-5-i386-THIRDPARTY I did do a cobbler reposync after creating the latest repo "RHEL-5-i386-TEST" with cobbler 1.6.3. All other repos where created with previous versions of cobbler. Can anyone out there help me understand what is going on here? I am running cobbler 1.6.3 on RHEL 5 x86. Regards, Nick
