Description zhonglinzhang 2013-09-24 05:38:36 EDT
Description of problem:
Boot win8 with "-vga cirrus -vnc :3" in qemu-kvm command line, then can not support s4 in guest. But use this order "-vnc :3 -vga cirrus" to boot guest, then s4 is successful.

Version-Release number of selected component (if applicable):
host kernel: 2.6.32-419.el6.x86_64
qemu-kvm: qemu-kvm-

How reproducible:

Steps to Reproduce:
1. Boot win8 guest with the following command line:
/usr/libexec/qemu-kvm -M pc -enable-kvm -m 4G -smp 4,sockets=1,cores=4,threads=1 -name test -rtc base=localtime,clock=host,driftfix=slew  -k en-us  -boot menu=on  -vga cirrus  -vnc :3   -usb -device usb-tablet -global PIIX4_PM.disable_s3=0 -global PIIX3_PM.disable_s4=0  -monitor stdio       -drive file=/home/win8-32.raw,if=none,id=drive-system-disk,media=disk,format=raw,aio=native,werror=stop,rerror=stop -device virtio-blk-pci,drive=drive-system-disk,id=system-disk,addr=0x9     -netdev tap,id=hostnet0,vhost=on,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,id=virtio-net-pci0,mac=00:22:15:27:54:8d,bus=pci.0,addr=0x8

2. In win8 guest:
powercfg -a


Actual results:
With "-vga cirrus  -vnc :3" order, can not support s4

Expected results:
It should be support s4

Additional info:
With "-vnc :3 -vga cirrus" order:
It can support s4.

How about RHEL7 host?

> How about RHEL7 host?

Test this issue with RHEL7 host:
kernel: 3.10.0-22.el7.x86_64
qemu-kvm: qemu-kvm-rhev-1.5.3-3.el7.x86_64

Actual Results:
Boot win8 with "-vga cirrus -vnc :3" in qemu-kvm command line, then can not support s4 in guest. But use this order "-vnc :3 -vga cirrus" to boot guest, then s4 is successful.

S3/S4 support is tech-preview in RHEL6 and it'll be promoted to fully supported
at some point, but only in RHEL7.

Therefore we're closing all S3/S4 related bugs in RHEL6. New bugs will be
considered only if they're regressions or break some important use-case or

RHEL7 is being more extensively tested and effort from QE is underway in
certifying that this particular bug is not present there.

Please reopen with a justification if you believe this bug should not be
closed. We'll consider them on a case-by-case basis following a best effort

Thank you.
