Re-test this case with win2k8-64 guest. This issue also exists. And, if install the win2k8-64 guest with ide block, then boot it with ide block too, it takes a few seconds to hibernate. BUT, if install the win2k8-64 guest with virtio block,then boot it with ide block. it will take 10 minutes to hibernate. (In reply to comment #4) > Re-test this case with win2k8-64 guest.

Looks like Windows issue to me. Can you retest this one more time? Also can you check that if you instal win2k3 with ide it hibernates fast with ide?

I re-test win2k3-64 and win2k8-64 in the same large host, on the latest kvm version(the version in bug description is too old). kvm: kvm-83-181.el5 kernel:2.6.18-194.el5 But , can not reproduce it any more. I installed win2k3 and win2k8-84 guest with virtio block, and then did the following hibernate test: if=ide if=virtio win2k3-64: OK OK win2k8-64 OK OK So this issue does not exsit in the latest rhle5.6 kvm version but don't know why. Closing for now then. |
Description of problem: Win2k3 guest last long time during hibernating with ide block in large host(96 cpu and 1000G mem). ide block virtio block win2k3-32 15 minutes 1 minutes win2k3-64 25 minutes 2 minutes I test it in small host(4 vpu and 4G mem), it works well. Guest can hibernate and resume quickly. The command line I used: /usr/libexec/qemu-kvm -no-hpet -usbdevice tablet -rtc-td-hack -m 2G -smp 2 -drive file=/opt/win2k3-32-virtio-virtio.raw,media=disk,if=ide,index=0 -net nic,vlan=0,macaddr=10:1a:4a:10:20:5f,model=rtl8139 -net tap,vlan=0,script=/etc/qemu-ifup -uuid `uuidgen` -cpu qemu64,+sse2 -notify all -vnc :2 -monitor stdio -boot c Version-Release number of selected component (if applicable): kvm-83-150.el5 kernel: 2.6.18-185.el5 How reproducible: Always Steps to Reproduce: 1.boot a win2k3 guest using ide block with the above command line. 2.enable hibernate inside guest by: input #powercfg -h on in command prompt. 3.hibernate the guest by: click "start" menu -> shutdown -> hibernate Actual results: It takes about 25 min for win2k3-64 guest and 15 min for win2k3-32 guest during hibernate with ide block. I test with the same guest image and command line using virtio block, it takes only 1 or 2 min to hibernate. Expected results: Guest can hibernate and resume within a short time.
