Description

Verified with kernel-2.6.32-71.34.1.el6.
There is no call trace message in guest (i386 and x86_64 RHEL6.0 PV DomUs) kernel log after save/restore with the fix applied.
Also tried with {i386|x86_64} x {PV|HVM} DomUs (2 vcpus) , save/restore works well with the fix applied.
The tests were ran against Intel platform as microcode module can't be loaded successfully on AMD platform (RHEL 6.0 GA kernel).
