There where some issues with the previous branch (pvhvm_v14), I've
pushed a new one (pvhvm_v16) that fixes the following bugs:
* Make sure there are no IPIs in flight while the VM is migrated,
having in-flight IPIs is a problem because on resume the event channels
are re-initialized, so all pending events are lost, including IPIs.
* Reset the clock after migration, this prevent clock drifts when the
VM is migrated.
* blkfront was not correctly freeing the old event channel port.
The following two commits are needed for Xen:

wallclock time for PVHVM on migration

With this branch I've been able to successfully local migrate a busy VM
400 times consecutively.
As usual, the branch can be found here:
