Hi,

I'm facing stalled x86-64 guests after live migration when using kvm
(share disk images). This does not happen with x86-32 guests or when
disabling kvm. Both qemu and qemu-kvm git heads are affected (recent
vmstate fixes applied). Running I/O load during the migration (e.g. a
simple "ls -R /") seems to trigger it reliably.

Can anyone confirm / comment on this? Do we fail to restore some magic
state that only long mode cares about?

Jan
