Andreas,
actually, I think Shankhadeep is right. Does the VM go back to running
after a few minutes in shutdown? If the VM doesn't have the acpid package
installed, it won't shutdown on the shutdown event, thus never going into
the epilog state.
Can you make sure that you have acpid installed? (does it log you off when
you onevm shutdown the vm?)
You could also try with onevm cancel. That will destroy the vm
instantaneously and call the epilog...
Cheers,
Jaime
