This sounds bad :-) Can you provide the output of 'xm list --long hd_domain'
immediately after defining it, and then again immediately after starting
the guest.
Here's the whole create process. Probably more than you needed, but
included for clarity ;)
# virsh list --all
Id Name State
----------------------------------
0 Domain-0 running
# virsh define hd_domain
Domain hd_domain defined from hd_domain
# xm list --long hd_domain
Error: Domain 'hd_domain' does not exist.
Usage: xm list [options] [Domain, ...]
List information about all/some domains.
-l, --long Output all VM details in SXP
--label Include security labels
