Stategery regarding Windows support for mixed environments
by Michael DeHaan 03 Apr '09

03 Apr '09

This is a development branch thing but it's related to Cobbler's plan moving forward, so it seems best to discuss here. So ... there's been some good work going so far towards supporting some variants of Windows, though I see it may perhaps be somewhat of an evolutionary dead-end. The web page for RIS-Linux in particular does not mention Vista or 2008. Further, I am much more interested in supporting Windows virtually than physically -- this should be natural with the increasing interest in virtualization and recent interoperability agreements with Microsoft. For the devel branch (1.7), I'd rather we refocus our efforts into making sure the experience for Windows installs, virtually, is as good as possible. The upside of this is that most of the infrastructure is already in place -- we can already do ISO based fullvirt installs ("cobbler image add" with the ISO file residing on NFS) and a next step is to teach it about a virtual floppy drive with the SIF answer file on the drive, so it can be fully scripted. We already also have the "virt-clone" image type, for being able to take an existing disk image and repeatedly clone that image with koan, keeping the same source image on NFS. (The syntax here is "koan --image=foo --virt", just like with the ISO based installs for virt). The goal here is to not invest too much effort in supporting dead-end deployment areas and writing code to cater to say, XP vs Vista vs 2003 vs 2008, but handle things generically, with answer files, and images, things we already do. On the plus side, there's also much less work in doing this and no additional dependencies or things to configure and set up. Rather than physical deployments this encourages deploying Windows on Linux hosts, which makes the Windows machines easier to manage since you can run tools like libvirt and Func on the hosts. See http://www.redhat.com/promo/svvp/ Windows belongs running on virt. In general, for non-Linux OS's, we should also concentrate on virt. --Michael

http proxy setting for repo to mirror locally
by Leonid Flaks 02 Apr '09

02 Apr '09

Hi ! I would like to provision rpmfusion repos in cobbler. I can access them only through the web proxy. Is it supported in cobbler? What would be the right place to put the proxy setting for those repos? The proxy support has been added recently to anaconda during manual installation, but I could not find any way to put it in kickstart, so just adding 'repo= ' does not work. I found that anaconda uses /tmp/anaconda-yum.conf (or so it seems) for yum configuration and tried to put proxy settings there in pre script - did not have any effect. Another thing I tried - to mirror it locally - then 'cobbler reposync' would need to be configured to use proxy. For now I just use post install - configure yum and run 'yum install' in scripts. I am using cobbler 1.4.3-4 on fedora 10, repo is set as http:// Thanks, Leon

After installing cobbler 1.6.2 I attempted to run a sync from the webui. It came back with this error in the cobblerd.log: 2009-04-02 14:06:16,135 - api - sync 2009-04-02 14:06:16,195 - api - Exception occured: exceptions.OSError 2009-04-02 14:06:16,195 - api - Exception value: [Errno 2] No such file or directory 2009-04-02 14:06:16,196 - api - Exception Info: File "/usr/lib/python2.4/site-packages/cobbler/remote.py", line 1566, in _dispatch return method_handle(*params) File "/usr/lib/python2.4/site-packages/cobbler/remote.py", line 1071, in sync return self.api.sync() File "/usr/lib/python2.4/site-packages/cobbler/api.py", line 553, in sync return sync.run() File "/usr/lib/python2.4/site-packages/cobbler/action_sync.py", line 140, in run utils.run_triggers(self.api, None, "/var/lib/cobbler/triggers/change/*") File "/usr/lib/python2.4/site-packages/cobbler/utils.py", line 690, in run_triggers rc = m.run(api, arglist) File "/usr/lib/python2.4/site-packages/cobbler/modules/scm_track.py", line 46, in run scall(["git","init"]) File "/usr/lib/python2.4/site-packages/cobbler/modules/scm_track.py", line 22, in scall op = sub_process.Popen(args, shell=False, stdout=sub_process.PIPE, stderr=sub_process.PIPE) File "/usr/lib/python2.4/site-packages/cobbler/sub_process.py", line 542, in __init__ errread, errwrite) File "/usr/lib/python2.4/site-packages/cobbler/sub_process.py", line 975, in _execute_child raise child_exception Here is me attempting to run cobbler check: --- SNIP --- # cobbler check The following potential problems were detected: #0: yum-utils need to be at least version 1.1.17 for reposync -l, current version is 1.1.16 # yum info yum-utils Loaded plugins: rhnplugin, security epel | 2.1 kB 00:00 rpmforge | 1.1 kB 00:00 Installed Packages Name : yum-utils Arch : noarch Version : 1.1.16 Release : 13.el5 Size : 189 k Repo : installed Summary : Utilities based around the yum package manager URL : http://linux.duke.edu/yum/download/yum-utils/ License : GPLv2+ Description: yum-utils is a collection of utilities and examples for the yum package manager.

I am using koan to deploy a Xen guest, "Virt Path" for the system is set to the volume where I want the virtualdisk created. koan was able to created the disk but the installation failed, because koan is trying to set SELinux context of the LV, it created.

Exception on profile save in WebUI
by Stephan Huiser 02 Apr '09

Hi, I'm working on Cobbler / Puppet integration. - I set 'Management Classes' of profile 'centos-5.2-xen-x86_64' to 'base'. - After clicking Save button, I get the following message: 'Error while saving profile' - I found the error below in cobblerd.log : 2009-04-02 01:39:40,840 - api - save_profile; user(admin); object_id(profile::centos-5.2-xen-x86_64) 2009-04-02 01:39:40,840 - api - calling authorize for resource ['save_profile', <cobbler.item_profile.Profile instance at 0xb7c14d0>, None]; user(admin) 2009-04-02 01:39:40,840 - api - authorization result: True; user(?) 2009-04-02 01:39:40,840 - api - add_profile; ['centos-5.2-xen-x86_64'] 2009-04-02 01:39:40,840 - api - saving profile centos-5.2-xen-x86_64 2009-04-02 01:39:40,845 - api - Exception occured: cobbler.cexceptions.CX 2009-04-02 01:39:40,845 - api - Exception value: 'error in system lookup for web01' 2009-04-02 01:39:40,845 - api - Exception Info: File "/usr/lib/python2.4/site-packages/cobbler/remote.py", line 1566, in _dispatch return method_handle(*params) File "/usr/lib/python2.4/site-packages/cobbler/remote.py", line 1238, in save_profile return self.api.add_profile(obj) File "/usr/lib/python2.4/site-packages/cobbler/api.py", line 383, in add_profile rc = self._config.profiles().add(ref,check_for_duplicate_names=check_for_duplicate_names,save=save) File "/usr/lib/python2.4/site-packages/cobbler/collection.py", line 276, in add self.lite_sync.add_single_profile(ref.name) File "/usr/lib/python2.4/site-packages/cobbler/action_litesync.py", line 112, in add_single_profile self.add_single_profile(k.name, rebuild_menu=False) File "/usr/lib/python2.4/site-packages/cobbler/action_litesync.py", line 114, in add_single_profile self.add_single_system(k.name) File "/usr/lib/python2.4/site-packages/cobbler/action_litesync.py", line 137, in add_single_system raise CX(_("error in system lookup for %s") % name) - When I do a 'cobbler system dumpvars --name=web01.dmz.huiser.local | grep mgmt_classes', I see that the system (via profile 'centos-5.2-xen-x86_64' -> 'web-server') actually has a management class 'base'. - message "Exception value: 'error in system lookup for web01'" shows cobbler is looking for info on 'web01', which is the name of te system before I renamed it to 'web01.dmz.huiser.local' .... - After a 'service cobbler restart' it works fine. Altering 'base' to 'base test' works as it should be ... I suspect there's still a cache problem. Do you need more info? -Stephan

'type' field
by Tom Brown 01 Apr '09

01 Apr '09

Is there any chance we could get a type field into cobbler - similar to the description field? I'd really like to be able to use logic on this field to decide on what packages to install. I could use the description field for this but its a bit free form and would be nice to be able to have a small field where we can add this info into. If it were easy to do that would be great but if not then no biggie thanks
