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 xiywang 2016-03-02 03:00:54 UTC 
Description of problem:
When recovering from s4 or s3 test, cannot boot graphic interface both on spice or vnc while only serial can work.
After waitting a few minutes in serial, call trace appread.

Version-Release number of selected component (if applicable):
host and guest kernel:
3.10.0-351.el7.x86_64
host qemu-kvm:
qemu-kvm-rhev-2.3.0-31.el7_2.8.x86_64

How reproducible:
100%

Steps to Reproduce:
1. boot a guest
/usr/libexec/qemu-kvm -name RHEL7.3-Guest -cpu SandyBridge -m 4G -smp 2 \

-drive id=drive_image1,if=none,cache=none,snapshot=off,format=qcow2,file=/home/virtkvmqe-x86-cpu-hotplug.qcow2 -device virtio-blk-pci,id=image1,drive=drive_image1 \

-netdev tap,id=hostnet0,vhost=on,script=/etc/ovs-ifup,downscript=/etc/ovs-ifdown -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:55:01:77:89:40 \

 -device qxl-vga,id=video0 -spice port=5900,disable-ticketing \

-monitor stdio -qmp tcp:0:4444,server,nowait -serial unix:/tmp/console,server,nowait \

-global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -vnc :1

2. do s4 or s3 in guest
echo disk > /sys/power/state
or
echo mem > /sys/power/state

3. resume

Actual results:
only serial can work
guest GUI doesn't work
guest show call trace

Expected results:
both vnc, spice and serial should work fine

Additional info:

1.RHEL7.2 release version qemu-kvm-rhev-2.3.0-31.el7 hit the same issue

2.get call trace in guest:

Comment 2 Ademar Reis 2016-03-08 18:57:48 UTC 
We do not support S3/S4, so I'm closing it as wontfix.
