RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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

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
