[Fedora-xen] Cannot erase unsuccessfully created guests

[Gastón Keller]

Hello, list. I've been playing with Xen lately and it was only until
yesterday that I could successfully create a guest with Fedora 8
installed on it (the one with name _cero_). The problem is that all
the previous attempts have generated _records_ that I cannot erase.
The following is from the terminal:

[root at alfa11 gkeller2]# virsh list
 Id Name                 State
----------------------------------
  0 Domain-0             running
 10 cero                 blocked

It seems virsh doesn't detect those records, but xm does. Also, virsh
cannot destroy them (what makes sense if it cannot see them), neither
can xm.

My problem is that, as far as I know, those _records_ of failed guest
have memory assigned from dom0 and they affect the creation of new
guests.

Any suggestions?

Thank you in advance,
Gaston
