Description Qunfang Zhang 2012-03-16 10:32:30 UTC
Description of problem:
Suspend guest to mem with virtio scsi disk, guest reboot instead of suspend. 
I disabled "-kvmclock" to avoid bug 803132. And I only hit this problem once after more than 20 times attempts.

I got the guest serial output when hitting the problem. Please check the attachment.

Version-Release number of selected component (if applicable):
Host:
kernel-2.6.32-251.el6.x86_64
qemu-kvm-0.12.1.2-2.246.el6.x86_64
Guest:
kernel-2.6.32-251.el6.x86_64

How reproducible:
1/20 

Steps to Reproduce:
1. Boot guest with virtio scsi disk and disable kvmclock to avoid bug 803132.
 /usr/libexec/qemu-kvm -M rhel6.3.0 -cpu Conroe,-kvmclock -enable-kvm -m 4G -smp 2,sockets=1,cores=2,threads=1 -name rhel6.3 -uuid 4c84db67-faf8-4498-9829-19a3d6431d9d -rtc base=localtime,driftfix=slew -drive file=/home/rhel6.3-64.raw,if=none,format=raw,id=scsi0 -device virtio-scsi-pci,id=scsi0 -device scsi-hd,drive=scsi0 -netdev tap,id=hostnet0,script=/etc/qemu-ifup -device e1000,netdev=hostnet0,id=net0,mac=00:1a:2a:42:10:66,bus=pci.0 -usb -device usb-tablet,id=input0 -boot c -monitor stdio -qmp tcp:0:4444,server,nowait -chardev socket,id=charserial0,path=/tmp/qzhang-isa,server,nowait -device isa-serial,chardev=charserial0,id=serial0 -drive file=/home/boot.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -spice port=5930,disable-ticketing -vga qxl -global qxl-vga.vram_size=33554432

2.Inside guest :#pm-suspend or #echo mem > /sys/power/state

3.Resume guest and repeat step 2.
  
Actual results:
Guest reboot.

Expected results:
Guest should suspend and resume successfully.

Likely a dup of bug 802127.

Could someone from QA please confirm if this is still reproduced with latest RHEL6.3 (Bug 802127 has been verified)? Thanks.

Test this issue with the same steps in comment 0 and the following configuration:

# uname -r;rpm -q qemu-kvm
2.6.32-279.el6.x86_64
qemu-kvm-0.12.1.2-2.295.el6.x86_64


1. Boot guest with virtio scsi disk and disable kvmclock to avoid bug 803132.
/usr/libexec/qemu-kvm -M rhel6.3.0 -cpu Conroe,-kvmclock -enable-kvm -m 4G -smp 2,sockets=1,cores=2,threads=1 -name rhel6.3 -uuid 4c84db67-faf8-4498-9829-19a3d6431d9d -rtc base=localtime,driftfix=slew -drive file=/home/rhel6.3-64.raw,if=none,format=raw,id=scsi0 -device virtio-scsi-pci,id=scsi0 -device scsi-hd,drive=scsi0 -netdev tap,id=hostnet0,script=/etc/qemu-ifup -device e1000,netdev=hostnet0,id=net0,mac=00:1a:2a:42:10:66,bus=pci.0 -usb -device usb-tablet,id=input0 -boot c -monitor stdio -qmp tcp:0:4444,server,nowait -chardev socket,id=charserial0,path=/tmp/qzhang-isa,server,nowait -device isa-serial,chardev=charserial0,id=serial0 -drive file=/home/boot.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -spice port=5930,disable-ticketing -vga qxl -global qxl-vga.vram_size=33554432 -bios /usr/share/seabios/bios-pm.bin

2.Inside guest :#pm-suspend or #echo mem > /sys/power/state
  wakeup guest by command system_wakeup or press any key.

3.Repeat step 2 more than 100 times

After step 3, guest can suspend and resume successfully.
