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":

1243049642.635572, "owners": ["admin"], "name": "win7", "virt_ram":
"<<inherit>>", "power_id": "", "random_id": "FQ3L", "server":

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!
