Description Qunfang Zhang 2011-03-16 02:09:58 UTC 
Description of problem:
Running virtio serial "Common Scenario Stress With IO", the win2k8-32 image corrupted after 3 times attempt. Other guests are ok.
Every times I start to run, I copy a fresh backup win2k8-32-sp2 image with MS system update. But all failed. I can not get any log except the screenshot. Guest can not boot up again even though I boot it without the serial device.
Anyway, I will re-install a win2k8-32 guest and have a try.

Version-Release number of selected component (if applicable):
virtio-win-prewhql-0.1-6
kernel-2.6.32-120.el6.x86_64
qemu-kvm-0.12.1.2-2.148.el6.x86_64

How reproducible:
3/3

Steps to Reproduce:
1.Prepare whql test environment.
2.Run win2k8-32 serial whql testing "Common Scenario Stress With IO" job.
Cli:
/usr/libexec/qemu-kvm -m 6G -smp 4 -cpu cpu64-rhel6,+x2apic -usbdevice tablet -drive file=win2k8-32-serial.raw,format=raw,if=none,id=drive-ide0-0-0,werror=stop,rerror=stop,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -netdev tap,id=hostnet0,script=/etc/qemu-ifup1 -device e1000,netdev=hostnet0,mac=00:10:20:3d:39:1c,bus=pci.0,addr=0x4,id=net0 -boot c -uuid 631bf1d8-2f02-4bb6-9f38-8076adc28620 -rtc-td-hack -no-kvm-pit-reinjection -monitor stdio -name win2k8-32-serial -vnc :10 -device virtio-serial-pci,id=virtio-serial0,max_ports=16,vectors=4,bus=pci.0 -chardev pty,id=channel0 -device virtserialport,chardev=channel0,name=org.linux-kvm.port.0,bus=virtio-serial0.0

Hi, Qunfang

Could you please try reproducing this problem with the same
image and vioserial driver from virtio-win-1-1-16 package?

Thank you,
Vadim.

Ok, I will try.

Also please test w/o not virtio-serial, just run the test on another driver like virtio-balloon or usb

Hi, Dor and Vadim
I re-install a new win2k8-32-sp2 guest and do system update. Then re-test the whql virtio serial "Common Scenario Stress With IO". It passed.
So, maybe the old backup image is copied for many times and has some problem? Not sure, I will change this bug's priority to medium and follow it.
If we never hit this issue in the following test, I will close it as NOTABUG.

Thanks
Qunfang

ok, let's wait a week and close it if it won't happens again

Re-test with virtio-win-prewhql-0.1-7 for 2 times. This issue does not exist. So I will close it as NOTABUG. Thanks.
