Hello,

Im trying to add an IP alias to domU.
I have the same netmask and broadcast as eth0. I can ping IP of eth0:1
from domU and dom0. But not outside dom0. Any ideas?

I don't know your exact setup, but I would suggest it is a routing problem.

Outer machines do not know, how to reach the alias IP. Packets to the
alias ip should probably be routed to dom0 from outside.

Both eth0 and eth0:1 has IPs which are on the same subnet, same netmask and broadcast. It could not be a routing issue. :(
