Description Sibiao Luo 2014-12-03 10:14:17 UTC 
Description of problem:
Found this bug when replied bug 949900.
According to Bug 1111107 that Q35 is no longer "tech preview" in RHEL7.x and is simply now unsupported (it will only be in qemu-kvm-rhev). And checked with Amit in IRC that both (q35 and s3/s4) are techpreview.

Version-Release number of selected component (if applicable):
# uname -r && rpm -q qemu-kvm-rhev
3.10.0-211.el7.x86_64
qemu-kvm-rhev-2.1.2-14.el7.x86_64
guest info:
3.10.0-211.el7.x86_64

How reproducible:
3/3

Steps to Reproduce:
1.boot up a rhel guest with "spcie+ qxl" under Q35 chipset without "-global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0" specified in command line.
2.do S3 and resume it, check the VM status and guest kernel log.
3.do second S3.

Actual results:
after step 2, do s3 and resume it successfully.
after step 3, it fail to s3 again and the vm status still running.

Expected results:
it can repeat do s3 and resume it successfully.

Hit another problem:
Host kernel:
kernel-3.10.0-220.el7.x86_64
qemu-kvm-rhev-2.1.2-17.el7.x86_64

1.Boot a guest with -M q35
2.Do S3 and wakeup
3.Do S4 

Result：
after step2 ,do s3 and resume it successfully. 
after step3 ,it fail to s4 and the vm status still running.
