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

Hi Scott:

Thanks again.
> What os is your dom0 running?

LSB Version:
:core-3.1-amd64:core-3.1-ia32:core-3.1-noarch:graphics-3.1-amd64:graphic
s-3.1-ia32:graphics-3.1-noarch
Distributor ID: CentOS
Description:    CentOS release 5.5 (Final)
Release:        5.5
Codename:       Final

Xen: 3.4.3 (at least it would be if xend started :-) )

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?

Cheers,

Joe

Try 'virsh start foo'.  That is what we use.  I'd also go looking in
/etc/xen for foo.  That is where xm is going to go looking.  What os is
your dom0 running?
