Description Mike Cao 2010-05-12 08:04:07 UTC
Description of problem:
 BSOD occurred after live migration without shared storage 

Version-Release number of selected component (if applicable):
Host:
# uname -r
2.6.32-23.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.48.el6.x86_64
Guest:
Windows 2008 r2

How reproducible:
test 2 times,100% reproduced.

Steps to Reproduce:
1.start a vm with in source host with:
/usr/libexec/qemu-kvm -rtc-td-hack -no-hpet -usbdevice tablet -drive file=/home/win2k8_r2,if=virtio,format=raw,boot=on -net nic,macaddr=20:10:43:23:23:12,model=virtio,vlan=0 -net tap,script=/etc/qemu-ifup,vlan=0 -uuid `uuidgen` -vnc :7 -boot dc -cpu qemu64,+sse2 -smp 2 -balloon none -startdate now -monitor stdio
2.start another with in dest host with:
/usr/libexec/qemu-kvm -rtc-td-hack -no-hpet -usbdevice tablet -drive file=/home/test2.raw,if=virtio,format=raw,boot=on -net nic,macaddr=20:10:43:23:23:12,model=virtio,vlan=0 -net tap,script=/etc/qemu-ifup,vlan=0 -uuid `uuidgen` -vnc :8 -boot dc -cpu qemu64,+sse2 -smp 2 -balloon none -startdate now -monitor stdio -incoming tcp:0:5888
Noticed that the image is not the same image in step1.
3.in the source host qemu monior type:(qemu) migrate -b tcp:<ip>:5888
  
Actual results:
after step 3 ,the guest is BOSD.

Expected results:
after migration ,the guest can be used normally.

Additional info:
When BOSD ,reboot it ,the guest can be used normally.

It's expected for the migration to work for the storage images be the same. Can't really say this is a bug.
