Hello,

I have tested Xen live migration with HVM guests on xen 3.4.3 and
4.1.2.  In both cases, the guest migrated successfully but ping from
outside failed due to layer2 address-table not being updated on
switch.  Once the guests initiates network traffic, then pings from
outside work.

I've searched Xen mailing lists and wiki and haven't found any
definitive information about gratuitous ARP for HVM/qemu guests.

If someone could point me in the right direction - source code,
documentation, or otherwise, it would be much appreciated.


Thanks,

Mark
