Put your domains in /etc/xen and remove the path attribute.  'virsh'
does not have a way to specify alternative search paths, consequently,
using 'path' requires use of 'xm'.

Federico's 'xmlfile' patch allows vm.sh to take a name + a full path to
a libvirt .xml file for using virsh, but it's not in RHEL.
