[Xen-users] Debian/squeeze: domU live migraton hangs

[Jean-Francois Malouin <Jean-Francois.Malouin@xxxxxxxxxxxxxxxxx>]

Hi,

In view of the problems I was having with DomU network timeout after a
live migration (I posted that problems here a while ago but never got
anything except from private emails) I finally updated my
Debian/Squeeze Dom0s last night to a new kernel, from 2.6.32-23 to
2.6.32-26. 

Now live migration just hangs...Any ideas?

which is from linbit):
