[TriLUG] Xen: Identifying Host from Guest

[Ken Mink]

I don't think that's going to work. The guest's (DomU's) have eth0
with it's own MAC address. On the Dom0, there are vifX's and vethX's
for each of the DomU's. They use MAC addresses of ff:ff:ff:ff and
00:00:00:00 respectively. There doesn't seem to any way to correlate
them that way.

I appreciate it, though.
