[Xen-users] Arp not sent after live migrations on xen-unstable

[Nathan March <nathan@xxxxxxxxxxxxxxxxxxxx>]

 Hi All,

Having an issue with xen-4.0-unstable where after completing a live 
migration, an arp is never sent out to update the switch with the new 
location of the mac address.
Network is configured as per libvirt's instructions with the xen 
network-script disabled and the bridge (xenbr0) always up.

Things work fine 10s after doing the migration once the switch has 
picked up the move, checking the mac address tables confirms it's still 
going to the old host. I've also confirmed that it's not going out at 
all via a span port on the switch.
Saw a bunch of postings a while ago regarding it, but nothing recent. 
Anyone have any insight on what might be wrong?
- Nathan
