[Xen-users] xenbr0 doesn't have an IP (should it?!)
My domU cannot communicate with anything other than the dom0. The dom0
has no problems with any kind of communications.
I have seen some posts that imply that xenbr0 should have an IP address,
however, I cannot verify that.
What works:
Ping Dom0->DomU
Ping DomU->Dom0
SSH, etc Dom0->DomU
SSH, etc DomU->Dom0
Anything Dom0->(internet, intranet)
What doesn't Work:
Anything DomU->(internet, intranet, including gateway)
Some Information:
Dom0 IP: 10.0.0.12
DomU IP: 10.0.0.13
Gateway IP: 10.0.0.1
Below are some config and status snapshots:

from everything I know, this looks like it should work.
Any ideas?
