I have a very simple configuration, as I mainly use cobbler to do
non-kickstart PXE installs and therefore don't have any systems defined.
Thanks,

Hi Jeremy,
Looking over your configuration I see you do have one system record,
stored as "win7.json". That's fine, you've encountered a Cobbler
bug because of it though. Here's the contents of that file:
{"comment": "", "kickstart": "<<inherit>>", "name_servers_search": [],
"ks_meta": {}, "kernel_options_post": {}, "image": "win7-x64_64",
"redhat_management_key": "<<inherit>>", "virt_path": "<<inherit>>",
"power_user": "", "kernel_options": {}, "name_servers": [], "mtime":
1243049642.635572, "template_files": {}, "gateway": "", "uid":
"MTI0MzA0OTY0Mi42NDk0MTE3MjQuNTAxOTc", "power_type": "ipmitool",
"virt_cpus": "<<inherit>>", "hostname": "", "mgmt_classes": [],
"power_pass": "", "netboot_enabled": true, "profile": "",
"virt_bridge": "<<inherit>>", "parent": "", "virt_type":
"<<inherit>>", "interfaces": {}, "power_address": "",
"virt_file_size": "<<inherit>>", "ctime": 1243049642.635572, "owners":
["admin"], "name": "win7", "virt_ram": "<<inherit>>", "power_id": "",
"random_id": "FQ3L", "server": "<<inherit>>",
"redhat_management_server": "<<inherit>>", "depth": 1}
It looks like 2.0 has a bug WRT image objects that we need to fix.
Our code to validate systems looks like this:
def check_if_valid(self):
if self.name is None or self.name == "":
raise CX("name is required")
if self.profile is None or self.profile == "":
raise CX("profile is required")
Basically the validation code assumes that the profile be set to
something, but for a systems object, it can also be "parented" from an
image. Either a profile or an image must be assigned, but not
both. This has drifted from what it used to do.
Images have largely been used by OVirt.org at this point (which, IIRC,
does not use system records), so I believe this warrants some
wholesale testing of the image chain, all the way through to koan.
They are clearly subject to a little bit of bitrot as I mostly
concentrate on kickstart installations. We need to fix this as well
as add-in a good series of tests to validate lesser-exercised sections
of the app, no doubt.
If you want to get the rest of Cobbler working for testing purposes,
you could temporarily move the win7.json file out the systems
directory and restart cobblerd. Profiles should work fine, though it
is clear we need to pound on images some more.
Thanks very much for the info!

I've pushed some changes into git that allow the image objects to be
loaded, and also fixed a CLI problem related to image adding/editing.
This should allow the basics around images to be workable.
We still need to go through the image based workflow and make sure
(end-to-end, through koan) everything is happy, though this should fix
your problem.
Based on this, we won't push 2.0.0 stock through to stable, we'll likely
do that with a 2.0.1.
Note -- I have a series of meetings and so forth next week, so my
ability to get images happy and working may be limited, though further
testing is welcome -- and I'll be right back on it as soon as
possible. If other folks want to help this along, be my guest. The
latest changes are all pushed to git.
Thanks!
