[BUG 2.6.32.y] Broken PV migration between hosts with different uptime, non-monotonic time?
Hello,
I encountered the following bug when migrating a Linux-2.6.32.54 PV domain on
Xen-3.4.3 between different hosts, whose uptime differs by several minutes (3
hosts, each ~5 minutes apart): When migrating from a host with lower uptime
to a host with higher uptime, the VM looses it''s network connection for some
time and then continues after some minutes (roughly equivalent to the
