through it.  You can then configure the vm's xml file to use it and/or 
put the change into the template file for libvirt.   There are 
side-effects.  Root access is needed to bring up the tap access for the 

There were assumptions made in that document that I'm still not sure I 
get.  NetworkManager fights against that process pretty hard, so you'll 
need to disable it (my update to the wiki).  Also, I'd suggest doing 
this configuration change locally or via a IP-based KVM switch since 
you're so far away.  My server got knocked off the net doing this the 
first time.  (FWIW, I work for a company that makes IP based KVM 
switches, and lemme tell you, it's nice, especially with virtual media).
