Description zhonglinzhang 2013-09-25 08:35:47 UTC 
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: 3.10.0-22.el7.x86_64
qemu-kvm: qemu-kvm-rhev-1.5.3-3.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Boot win8 guest with the following command line:
/usr/libexec/qemu-kvm -M pc -cpu SandyBridge -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

3.

Actual results:

Expected results:
It should be support s4

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

The only way to support Win8/2012 S3/S4 is with Vadim's new QXL drivers. The Cirrus drivers do not support it properly.
Please consult with Mike Cao

Ronen ,I think we always support s4 with VNC +QXL ,at least in RHEL6.x

zhonglinzhang ,Can you retest it with the latest qemu w/ -global PIIX4_PM.disable_s4=0 ?
Comment 4 zhonglinzhang 2013-12-27 10:36:39 UTC 
Retest this with 3.10.0-64.el7.x86_64 kernel and qemu-kvm-1.5.3-30.el7.x86_64
win2012R2 guest

With "-vga cirrus -vnc :3"  or "-vnc :3 -vga cirrus" can do s4 successfully.

-global PIIX4_PM.disable_s4=0... Maybe I made a mistake, always with PIIX3_PM.disable_s4=0
