Hello.

If I understand right, DomUs can't ping any Dom0 or any DomU that is not on the same physical machine.

I can see you do not specify a MAC address for your DomU's vif. As far as I remember, it makes Xen to generate the MAC on the fly. If DomU uses udev, it might think there is a new network interface on each boot, not eth0, so it fails to configure the network properly.

Please, show this output:
"xm list" from both of your Dom0.
"brctl show" from both of your Dom0.
"ifconfig" (and "ifconfig -a", if different) from your DomU.

Other test would be to try to ping DomUs from each other, as far as they are on the same physical machine, if your setup allows it.


Greetings.
