Recently, I found a problem with windows guest(both winxp and win7) that window
guest time passed very quickly, when restore vm that saved 1 hours ago.

Kvm server OS: Red Hat Enterprise Linux Server release 6.4

Reproduce Steps:
1. install a new windows xp vm named winxp.
2. power on the vm.
3. save the vm by command "virsh save winxp /tmp/winxp.save"
4. wait 10 minutes.
5. restore the vm by command "virsh restore /tmp/winxp.save"
6. Note the clock on the task bar, time passed as 10 time quickly as real time
speed.

--- Comment #1 from Gleb <gleb@redhat.com> ---
This is how it suppose to work. If you do not want this behaviour change
time catchup policy in libvirt.

BTW this bugzilla is for upstream issues, not vendor kernels.
