Re: [Xen-users] "received packet with own address as source address"

Hi Tiago,

well ... as I said before .. I wouldn't set your eth0 mac address (on
dom0 ) to the broadcast one ... 

Before setting the one on peth0, write it down and set eth0 (of your
Dom0, not the DomU's) to it.

That can be done easily on the init scripts (sorry, I use debian, so the
network scripts are completely different) :)

But the peth0 and xenbr0 mac addresses should be fe:ff:ff:ff:ff:ff  =)
