[Xen-users] UUID info and VIF info

[Erin Hughes <eredicatorx@xxxxxxxxxxxxxxx>]

A mistake in sys admining on my part has caused a major malfunction.

I created a domain called max01 and some where along the line I noticed 
that I deleted the host configuration file in /etc/xen/
YES a backup of /etc would be nice right now but, I do not have one.

[root@xen02 ~]# ls -l /etc/xen/

-rw-r--r-- 1 root root 5473 2007-11-15 08:35 xmexample.vti

I thought it should be trivial enough just look at a example on another 
machine.

vif = [ "mac=00:16:3e:5d:04:1c,bridge=xenbr0,type=ioemu" ]

It does not seem so difficult but where would I get the UUID info and 
VIF info?
