Using 'virsh create guest.xml' cmds can simply activate the guest, which 
only exist active domain instead of define domain,
and the guest will disappear if it isn't in define domain and you carry 
out some operations, e.g. 'destroy' or 'shutdown' or
'save' etc. so you should correctly use virsh cmds:
FYI,
virsh -c xen:/// define libvirt-ttylinux.xml
virsh start guestname
