Description mazhang 2013-03-29 03:42:11 UTC 
Description of problem:
Do s3 test with q35, the first time enter/resume normal, but the second time guest will wake up automatically.

Version-Release number of selected component (if applicable):
host:RHEL 7.0 Alpha3
kernel:3.9.0-0.rc3.44.el7.x86_64
qemu-kvm:qemu-kvm-1.4.0-1.el7.x86_64

guest:RHEL 7.0 Alpha3
kernel:3.9.0-0.rc3.44.el7.x86_64

client: RHEL 7.0 Alpha3
virt-viewer: virt-viewer-0.5.4-2.el7.x86_64


How reproducible:
100%

Steps to Reproduce:
1.Boot a guest
/usr/libexec/qemu-kvm \
-M q35 \
-cpu Opteron_G4 \
-m 4G  \
-smp 2,sockets=1,cores=2,threads=1 \
-name rhel7 \
-uuid 990ea161-6b67-47b2-b803-19fb01d30d12 \
-smbios type=1,manufacturer='Red Hat',product='RHEV Hypervisor',version=el6,serial=koTUXQrb,uuid=feebc8fd-f8b0-4e75-abc3-e63fcdb67170 \
-k en-us \
-rtc base=localtime,clock=host,driftfix=slew \
-enable-kvm \
-monitor stdio \
-qmp tcp:0:6666,server,nowait \
-boot menu=on \
-drive file=/root/images/rhel7-new.qcow2,if=none,id=drive-scsi-disk,format=qcow2,cache=none,werror=stop,rerror=stop \
-device virtio-scsi-pci,id=scsi0,addr=0x5 \
-device scsi-disk,drive=drive-scsi-disk,bus=scsi0.0,scsi-id=0,lun=0,id=scsi-disk,bootindex=1 \
-vga qxl \
-nodefaults \
-netdev tap,id=hostnet0,downscript=no,vhost=on \
-device e1000,netdev=hostnet0,id=net0,mac=00:1a:4a:2e:28:1c,bus=pcie.0,addr=0x4,bootindex=3 \
-chardev socket,path=/tmp/qga.sock,server,nowait,id=qga0 \
-device isa-serial,chardev=qga0,id=serial0 \
-spice port=5900,disable-ticketing \
-global PIIX4_PM.disable_s3=0 \
-global PIIX4_PM.disable_s4=0

2.Try enter s3 state
(in guest)#echo mem >/sys/power/state

3.Press keyboard wake up guest.
  
Actual results:
The first time guest can enter s3 state and wake up with press keyboard, but the second time guest will wake up in a second after enter s3.

Expected results:
guest s3 state can work well always.

Additional info:
also do s3 with pc-i440fx-1.4, this problem didn't happened.

I test the following version:
Host:
kernel-3.10.0-123.4.2.el7.x86_64
qemu-kvm-1.5.3-66.el7.x86_64
Guest:

Steps to Test:
1. boot a guest
# /usr/libexec/qemu-kvm \
-M q35 \
-cpu Opteron_G2 \
-m 4G  \
-smp 2,sockets=1,cores=2,threads=1 \
-name rhel7 \
-uuid 990ea161-6b67-47b2-b803-19fb01d30d12 \
-smbios type=1,manufacturer='Red Hat',product='RHEV Hypervisor',version=el6,serial=koTUXQrb,uuid=feebc8fd-f8b0-4e75-abc3-e63fcdb67170 \
-k en-us \
-rtc base=localtime,clock=host,driftfix=slew \
-enable-kvm \
-monitor stdio \
-qmp tcp:0:6666,server,nowait \
-boot menu=on \
-drive file=/mnt/rhel7-64-ga.qcow2,if=none,id=drive-scsi-disk,format=qcow2,cache=none,werror=stop,rerror=stop \
-device virtio-scsi-pci,id=scsi0,addr=0x5 \
-device scsi-disk,drive=drive-scsi-disk,bus=scsi0.0,scsi-id=0,lun=0,id=scsi-disk,bootindex=1 \
-vga qxl \
-nodefaults \
-netdev tap,id=hostnet0,downscript=no,vhost=on \
-device e1000,netdev=hostnet0,id=net0,mac=00:1a:4a:2e:28:1c,bus=pcie.0,addr=0x4,bootindex=3 \
-chardev socket,path=/tmp/qga.sock,server,nowait,id=qga0 \
-device isa-serial,chardev=qga0,id=serial0 \
-spice port=5900,disable-ticketing \
-global PIIX4_PM.disable_s3=0 \
-global PIIX4_PM.disable_s4=0 \
-serial unix:/tmp/tty0,server,nowait

2. do S3 inside guest
# pm-suspend

3. Press keyboard wake up guest

4. do S3 inside guest again
# pm-supspend

5. Press keyboard wake up guest

Actual results:
after step3, the guest can be resumed normally.
after step5, the guest cannot be resumed and the screen is always dark. Cannot use serial to connect the guest.

after step5, run "system-reset" on qemu-kvm side, qemu-kvm core dump as following:

Comment 7 huiqingding 2014-07-15 06:05:59 UTC 
I also use the same version and steps of comment 5 to test "-M pc", do pm-suspend for three times inside guest, the guest can be resumed normally each time.
Comment 8 Marcel Apfelbaum 2014-10-21 14:57:35 UTC 
S3 not yet supported for Q35. Deferred to 7.2 for qemu-kvm-rhev.
