Greetings,
I am playing around with libvirt, virsh and virt-manager (via QEMU kvm).
For testing purpose, through libvirt, I am setting up several machines, taking some snapshots and wiping out everything.
The weird thing is that once I open virt-manager, if my cleanup routine hanged in someway, I still see those machines.
If I list the domains (or snapshots, or pools) through virsh I don't see anything available.
Please note that I don't posses neither the disk image nor the (external disks) snapshots.
So here's the problem:
If I try to delete the machine on virt-manager I get the following error:
---------------------------
Error deleting virtual machine '191da985-cc43-44b9-85be-95dde6229791': Requested operation is not valid: cannot delete inactive domain with 3 snapshots
Traceback (most recent call last):

if ret == -1: raise libvirtError ('virDomainUndefine() failed', dom=self)
libvirtError: Requested operation is not valid: cannot delete inactive domain with 3 snapshots
---------------------------
The error if fixable changing in file
/usr/share/virt-manager/virtManager/domain.py
The line # 1127
self._backend.undefine()
with
self._backend.undefineFlags(
libvirt.VIR_DOMAIN_UNDEFINE_SNAPSHOTS_METADATA)
Standing to libvirt documentation is not possible to undefine a domain if it has snapshots; a forced undefine is available through the undefineFlags() function with the proper flag set.
I dind't provide a patch as this can be an unwanted change.
You may want to reimplement the deletion including a warning for the user or something else.
Anyway I can't figure out where those information are stored, virsh doesn't see anything about, on my HD no information are stored. If I restart QEMU, libvirt-bin or even my machine the VM still are there...
Thanks for the great tools provided anyway!
