[Xen-users] migration and loss of networking

[Michael Shuey <shuey@xxxxxxxxxxx>]

I'm using Xen 3.0.2 (the packages from Debian/etch, actually) built around 
2.6.16.9 for all dom0s and domUs.  I recently finished building a 
multipathed SAN between a couple dom0 boxes, so I tried live migration.  
Suprisingly, my domU made it through and the block devices worked, but eth0 
stopped functioning.

I do see a vif0 in the new domU, and it is connected to the right bridge, 
but it doesn't work - packets sent in don't come out.  If I shut down the 
domU, and start it up again on the destination dom0, networking works fine.  
Of course, if I migrate it back to the first dom0, networking breaks 
again...

Any ideas why my ethernet devices aren't working after migration?
