Summary: sles10sp2 guest timer run too fast
Initial Comment:
With kvm.git Commit:7ff90748cebbfbafc8cfa6bdd633113cd9537789
qemu-kvm Commit:a1cd3c985c848dae73966f9601f15fbcade72f1, we found that sles10sp2 will run much faster than real, about 27s faster each after 60s real time.
Reproduce steps:
----------------
(1)qemu-system-x86_64 -m 1024 -net nic,macaddr=00:16:3e:6f:f3:d1,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -hda /share/xvs/var/sles10sp2.img
(2)Run ntpdate in guest: ntpdate sync_machine_ip && sleep 60 && ntpdate sync_machine_ip
Current result:
----------------
sles10sp2rc1-guest:~ # ntpdate sync_machine_ip && sleep 60 && ntpdate sync_machine_ip
31 May 23:16:59 ntpdate[3303]: step time server 192.168.198.248 offset
-61.27418
31 May 23:17:32 ntpdate[3305]: step time server 192.168.198.248 offset
-27.626469 sec
