Cobbler-side installs to KVM, VMware?

Eldred, Doug — 2012-05-25T17:51:41

I'm looking for an example, specifically showing the "power" settings in Cobbler, for how to initiate a Cobbler-side install to a KVM or VMware virtual machine.  Most of what I've found so far involves using koan, not using the Cobbler side to kick things off.

To my surprise, even though there's a "fence_vmware" command, Cobbler is unaware of it.  I've tried ipmitool based on one example, but haven't figured out the other power values to set in Cobbler.

Thanks in advance for any clues or documentation.

Regards,
Doug

Have you configured rsync? If so, can you test it between the two
servers to ensure there's no firewall or other issues blocking the
rsync from working? You can check for errors related to that as well
in /var/log/cobbler/cobbler.log

Thank you very much for your reply

I use cobbler replicate --master=192.168.0.1 --distros="CentOS-6.2*"
still not replicated.

Distros won't replicate if you use --omit-data, which results in the
profiles not replicating because their associated distros are not
present.

cobbler replicate: "unknown module"

David Lee — 2012-05-23T16:59:07

(Using cobbler 2.0.11 on RHEL 5.x)

We have a master cobbler server, and two slaves which run a daily cron:
    cobbler replicate --master=cobbler_master.our.org \
       --profiles="*" --systems="*"

In the master we set up a local repo of local RPMs, primarily designed 
for "yum" to access, but also referenced by cobbler.  This was set up:
    cobbler repo add --name=el5-x86_64-local \
       --mirror=http://... --mirror-locally=N --arch=x86_64

But the daily "cobbler replicate" gives an error message:

    received on stderr:
    Rsyncing repos
    running: rsync -avzH cobbler_master.our.org::repo-el5-x86_64-local 
/var/www/cobbler/repo_mirror/el5-x86_64-local
    received on stdout:
    received on stderr: < at >ERROR: Unknown module 'repo-el5-x86_64-local'
    rsync error: error starting client-server protocol (code 5) at 
main.c(1296) [receiver=2.6.8]

That "unknown module" error message is worrying.

Is this because of the "N" for "mirror-locally"?

Things seem to work OK, and last time we forced an instal

Stuart Sears — 2012-05-23T16:27:31

Vivek,

You need to provide more information if you expect folk to be able to 
help you. We can't guess what you've already done, you have to actually 
tell us. In detail.

A (not very) subtle clue:
http://catb.org/esr/faqs/smart-questions.html#before

Also, please compose a new email to the mailing list rather than just 
answering an existing one, if you are asking a new question. Otherwise 
your messages just get lost in the thread.

Oh and please try to send emails that aren't all on one line. :)

Right, now onto your question:

* What exactly have you already done to try and solve your problem?

* How did you import/add the RHEL distribution?
- just copy it into place? Were any cobbler commands involved at all?

* Can you manually access the images link that your installing VM is 
trying to find (try using a web browser)?

* What has this question got to do with cobbler?
It sounds like you are not trying to use cobbler at all. You may have 
installed it, but have you actually configured any distribution

On the nose!
That is exactly what happened.

Something set /var/log to 700.  Looking at other servers, it is set to 755.

Thanks, folks.  I found the what.  Now I need to find how/who.

It should continue to work until you bounce httpd again. The
permissions are only checked when the file descriptor is opened I
believe.

Dan White — 2012-05-23T14:07:26

Ah!  
"ps -ef | grep http" says that root owns the main process, but then apache owns all the child processes.

This still does not explain the behavior in toggling the permissions.

Re: Web interface suddenly stopped working

Dan White — 2012-05-23T14:03:53

To use one of my favorite literary quotes: Curiouser and curiouser !

Just to rule out a simple file permissions issue, I looked at the path to the log file:

Here's the before:

drwxr-xr-x 24 root   root   4096 Mar 19 15:54 /var
drwx------ 24 root   root   4096 May 23 04:02 /var/log
drwxr-xr-x  7 apache apache 4096 May 20 04:02 /var/log/cobbler/
-rw-r--r--  1 apache apache 1234 May 23 09:54 /var/log/cobbler/cobbler.log

So, I do this:
drwxrwxrwx 24 root   root   4096 Mar 19 15:54 /var
drwxr-xr-x 24 root   root   4096 May 23 04:02 /var/log
drwxrwxrwx  7 apache apache 4096 May 20 04:02 /var/log/cobbler/
-rw-rw-rw-  1 apache apache  844 May 23 09:48 /var/log/cobbler/cobbler.log

and the interface re-appears !

Now comes the weirdness: The interface continues to work/behave after I set the permissions back !

Re: Web interface suddenly stopped working

James Cammarata — 2012-05-23T14:00:18

Right, but it's mod_python that's throwing the error, meaning httpd is
trying to write to the file so it would be the apache user accessing
the file.

Thanks for responding, but I am not sure this helps.

Cobbler is run by root.

# ps -ef | grep cobbler
root      4260     1  0 08:23 ?        00:00:00 /usr/bin/python /usr/bin/cobblerd --daemonize

Additional oddities: I can run cobbler at the command line just fine.

Looks like someone broke the permissions/ownership on /var/log/cobbler
or some other directory. It could also be SElinux blocking access to
that file.


This can be ignored.

The messages reported by "cobbler check" are not necessarily errors.
Instead a lot of them are merely suggestions, especially when it comes
to optional features, so do not treat them as absolutes.

The following are potential configuration items that you may want to fix:

1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work.  This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
