Re: [Xen-users] Guest Network Some can Ping, Some can't Ping

Sorry for the last empty post....

Actually I only have 1 guest on Xen Server.
oh, by the way, I assign two ip for the guest1.  Like:
eth0 and eth0:0
one is for internal ip , the other is for external ip,
they are using same mac address, is that alright?
