Hi!
I have a (CentOS 5.4) machine that's running Cobbler 2.0.3, which was upgraded from Cobbler 1.6.x. Now I can't create any sub-profiles that work.
My first problem was that "--inherit" doesn't seem to exist in Cobbler 2, but it looks like "--parent" has taken its place.
Now onto the main problem.
With Cobbler 1.6.x, I could create a sub-profile like so:
cobbler profile add \ --name=core-vm \ --inherit=centos-5-4-xen-x86_64 \ --kickstart=/var/lib/cobbler/kickstarts/sample.ks \ --repos="centos-5-x86_64-base centos-5-x86_64-extras centos-5-x86_64-updates epel-5-x86_64" \ --name-servers=192.168.1.254 \ --name-servers-search=mydomain.com.au \ --virt-ram=768 \ --virt-file-size=12 \ --virt-path=vgvirt
After the upgrade to Cobbler 2, I tried to create a similar sub-profile, like so:
cobbler profile add \ --name=core-vm-test \ --parent=centos-5-4-xen-x86_64 \ --kickstart=/var/lib/cobbler/kickstarts/sample.ks \ --repos="centos-5-x86_64-base centos-5-x86_64-extras centos-5-x86_64-updates epel-5-x86_64" \ --name-servers=192.168.1.254 \ --name-servers-search=mydomain.com.au \ --virt-ram=768 \ --virt-file-size=12 \ --virt-path=vgvirt
The sub-profile appears to have been created OK, but in the WUI the new sub-profile has an empty Distro:
Name Distro Actions centos-5-4-x86_64 centos-5-4-x86_64 Edit ... centos-5-4-xen-x86_64 centos-5-4-xen-x86_64 Edit ... core-vm <<inherit>> Edit ... core-vm-test Edit ... rescue-centos-5-4-x86_64 centos-5-4-x86_64 Edit ...
When I try to use koan to create a VM based on the new sub-profile, it fails:

It looks like its missing the distro component of the path to the initrd image: http://cobbler/cobbler/images/~/initrd.img
I'm sure there should be a distro name where the '~' is.
If I create a VM based on the original sub-profile (created with Cobbler 1.6.x), then it works fine. I can even create a copy of a sub-profile, and use that as the basis for a system; that system will also install fine.
Any ideas where to start with this?
Is this a regression, or have I missed something that's different with Cobbler 2?

This is still a problem in 2.0.4, and it does indeed appear to be the result of the distribution not being inherited properly. For a profile and sub-profile being created with...
cobbler profile add --name=fc12-i386 --distro=fc12-i386 --kickstart=/var/lib/cobbler/kickstarts/resune.ks cobbler profile add --name=${release}-i386-xen --parent=${release}-i386 --kickstart=/var/lib/cobbler/kickstarts/${release}_xenguest.ks --ksmeta="drive=xvda" --virt-file-size=33 --virt-ram=512
we get

and dumpvars shows "distro : ~"
If we had a guide on how to debug the cobbler server, I would see what I could come up with, but right now, I have not had a chance to track down how to do this with the new structure and then track down the issue.
