xl destroy vm-name/ID-number fails

[axtpq4+b7c...@guerrillamail.com]

Hi,
there are some issues regarding the war the qubes-manager and the xl command line handles execution of arguments.

xl destroy ID fails and leaves the terminated machine hanging in an intermediate state that prevents restart of the vm (with or without sudo).
Qubes needs to be re-booted in order to restart the vm

@dom0 ~]$ xl destroy 5
libxl: cannot execute /etc/xen/scripts/block-snapshot: Permission denied

1. You should use virsh destroy instead.
2. Even if you must use xl for some reason, this tool needs to be called
as root.
