The MAC address should be FE:FF:FF:FF:FF:FF. The one above is the 
broadcast address. Not sure if it actually matters, but worth fixing 
anyway as it might confuse the bridge.
I had problems with ARP when I first started testing veth0. It turned 
out that domain0 was not applying the information in ARP packets to the 
ARP cache. Since the ARP cache wasn't kept up to date, I saw very weird 
IP behaviour.
I fixed that particular bug, but maybe there's another one. It is 
perhaps worth looking at /proc/net/arp and seeing how it compares with 
other machines on your network.
