Hi,
When I run
koan --list=profiles -s localhost
I get the following error

In the modules.conf I have

So I am a bit lost. Any thoughts ?

Restoring an inherited value for a child profile?
by Zack Perry
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

purpose of mgmt-class params?
by David Birdsong
I'm trying to understand the useful bridge between ansible and cobbler.
I've leveraged cobbler for installation and early configuration and it
works great.
I'm trying to figure out how to use cobbler variables to expose settings to
ansible. It appears that the default cobbler inventory script uses mgmt
classes to group machines and then ksmeta variables which follow the
inheritance patterns of ksmeta variables.
What I don't see ansible using is the mgmtclass params field. Even the help
message for
```cobbler mgmtclass edit ``` is a little confusing with the mention of
ksmeta in the --clobber flag while there exists no --ksmeta
flag--only params.
So what do people use mgmt params for?
I haven't looked, but do they trickle down to machine variables for
kickstarts?

cname records
by Greg Chavez
What's the trick to getting cname records into a system object? So
far, every time I set them in an interface via the Web console or via
the command line:
cobbler system edit --name=ceph-cs-sn-04i --interface=eth0 --cnames="ceph4"
Nothing gets set and there is not error reported.
Looking at the code here:
https://github.com/bytecar/cobbler/commit/25d0f7c924037b961c14fd5993d2848...
It would seem that it's a simple matter of entering each CNAME
delimited by space and in the case of the cobbler command, surrounded
by quotes.
I'm running the latest from epel-testing:
root@io-ns-03:/var/lib/cobbler/snippets> rpm -q cobbler cobbler-web
cobbler-2.4.0-1.el5
cobbler-web-2.4.0-1.el5
Thanks.

the process Cobbler: generating PXE menu structure - seems doesn't work
by Renato
Red Hat Enterprise Linux Server release 5.9 (Tikanga)
Cobbler 2.2.3
build time: Mon Jun 18 00:58:20 2012
Hello Everybody.
I am working on a Cobbler server for more 4 years without problem and all
work perfectly fine.
This morning , creating a new profile for my future "KVM" VirtualMachine .
So from Cobbler UI, I used the Configuration Profiles >> Create New
Profile.
This has been done. The "kickstart" seems look good. (checked via "View
Kickstart")
I ran a "cobbler sync" command : and no errors any more. (log below on the
email)
Now, When I boot with PXE , my newly profile freshly created doesn't show
on the PXE Menu. I got all profiles created except this new one :-/
checking on the main pxelinux config file :
/tftpboot/pxelinux.cfg/default generated by the process " PXE menu
structure " . my profile VMxxxx created is missing.
But from the Cobbler UI the profile is THERE with all the rest.
?? I suspect the issue is there when the function call the generating PXE
process . Somebody on the loop know if it's possible to get the log more
verbose ? regarding this two process named :
Wed Jun 26 11:22:30 2013 - INFO | generating PXE configuration files
Wed Jun 26 11:22:30 2013 - INFO | generating PXE menu structure
Thank you so much ,

ESXi support of server override
by Eddie Velez
I installed 2.4.0-1 and ran into a problem with server override in ESXi profiles. This no longer works with new cobbler-boot.cfg. In the profile there is an tab for Management and option for Template files this doesn't work. Is there a way to have multiple cobbler-boot.cfg files with different names to support different interfaces on the server.

RHEL - Error downloading kickstart file
by Janowiak, Edward
I can build CentOS 6.3 systems all day long with Cobbler. Whenever I try to build a RHEL 5.3, 5.5, or 6.3 system, I get 'Error downloading kickstart file'. Since I can build systems from some distros, I know this isn't a networking issue.
Any ideas how to troubleshoot this would be appreciated.

Django is missing from EPEL-5 repositories
by Dan White
I am setting up a new Cobbler server on a RHEL 5 64-bit server and when I gave it the command:
yum install cobbler cobbler-web cman koan
It tells me that there is a missing dependency package: Django > 1.1.2
yum deplist cobbler-web says:
package: cobbler-web.noarch 2.2.3-2.el5
dependency: mod_ssl
dependency: cobbler
dependency: /bin/sh
dependency: Django >= 1.1.2
dependency: mod_wsgi
A look thru the EPEL repoview shows that there is no package by that name in EPEL-5
Fortunately, I have a previous ly built Cobbler Server will mirrored repositories that had Django-1.1.4-1.el5.noarch.rpm in its epel-x86_64-mirror-rhel-5server repository.
What would one do if they did not have an old repo to fall back on ?

Sync fails to render DNS files following a replicate
by Greg Chavez
Just before I saw the announcement for cobbler 2.4.0-1, I upgraded my
beta RHEL5 installation to cobbler-2.4.0-beta6.el5. I synced my master
and everything looked good. Next, I upgrade my slave and ran a
replicate:
cobbler replicate --master=$master --distros="*" --profiles="*"
--systems="*" --repos="*" --prune
The replication portion went well, but the ensuing sync failed at this
point (from cobbler.log):
Thu Jun 20 18:37:51 2013 - INFO | rendering DNS files

The error also occurs after doing a "cobbler sync", although the
cobbler.log messages are different:
There are no errors if I change manage_dns from 1 to 0 in
/etc/cobbler/settings. The only thing I haven't done is check all my
500+ system entries for a weird ipv6_address entry (we don't use it).
Maybe this get fixed with the production 2.4.0-1 release? Thanks.
