Hi,
when I was testing live storage migration with libvirt
Can you give this patch a try? Should read the guest TSC values after
stopping the VM.
Yes, this patch fixes that.
Thanks,

Hi,
when I was testing live storage migration with libvirt I found out that
this patch can cause virtual machine to hang when completing mirror job.
This is (probably) b

When we migrate we ask the kernel about its current belief on what the guest
time would be. However, I've seen cases where the kvmclock guest structure
indicates a time more recent than the kvm returned time.
To make sure we never go backwards, calculate what the guest would have seen
as time at t
