Description yongdu 2013-09-02 09:15:40 UTC 
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.

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.
