xm create -c <domU> is failing: can't find config file for koan VM

[Joe Linoff]

Hi Folks:

I created two domU's using koan with the -nofgx switch:

dom0 % koan --virt --nogfx --system=foo
  dom0 % koan --virt --nogfx --system=bar

They both configured properly.

I then ran xm list:

Name                                        ID   Mem VCPUs      State
Time(s)
  Domain-0                                     0  1024    16     r-----
621.6
  foo                                       2048     2
0.0
  bar                                       2048     2
0.0

I then ran xm create -c foo and got this error:

dom0 # xm create -c foo
  Error: Unable to open config file: foo
  Usage: xm create <ConfigFile> [options] [vars]

I then ran xm create -c bar and got the same error:

dom0 # xm create -c bar
  Error: Unable to open config file: bar
  Usage: xm create <ConfigFile> [options] [vars]

It is probably the case that some sort of error occurred during the
configuration/setup phase. Unfortunately I had to go to a meeting and
missed the output.

How can I debug this?

Here is the output of --display for foo:

dom0 # koan --display --system=foo

Try using the full path to the config file:

xm create -c /path/to/file/foo

Thank you for the suggestion. What should that path be? There are no configuration files in /etc/xen on dom0.

Cheers,

Joe

Did you define a "virt-path" for this system in cobbler? If so, try
looking there. Otherwise find is your friend:

find / -name "foo" -print

Thank you for taking the time to offer these suggestions.
> Did you define a "virt-path" for this system in cobbler?

No. Is that a good thing to do? If so I will try it in the future.
> Otherwise find is your friend:

I tried find but did not find foo anywhere on the dom0 which leads me to believe that there was some sort of problem. I posted another NOOB question based on the fact that I could not find the xen cfg file...

Given that I did not define virt-path and find did not detect the cfg file, how do I debug this?

Regards,

Joe

Hi Scott:

Thanks again.

I re-provisioned my dom0. Everything built fine but xend didn't start.
There was a permissions error reported /var/log/xen/xend.log. I will
have to track that down and fix it before I try playing with domU's
again. I saw this once before and was able to fix things by rebooting
manually.

Do you have any ideas about how to fix the permissions problem?

Hi Scott:

I re-provisioned my system and tried 'virsh start foo' and it worked
like a charm.

Thank you,

Joe
