after the crash, libvirtd is still running 

# service libvirtd status
libvirtd (pid  3380) is running...

Tried virtio-win-1.1.16-4.el6 . Also met this crash .

Tried ide raw image as well . Didn't encounter the crash
Comment 4 Vivian Bian 2011-04-14 08:29:51 UTC 
seting blocker ? is because from libvirt functional testing, we did hotplug virtio disk -> partition the disk -> hot unplug virtio disk . Then if we got guest crash after partitioning , we can't do the hot unplug operation .
Comment 5 Vivian Bian 2011-04-14 09:13:29 UTC 
Repeat the operation for about 10 times , on 
http://download.englab.nay.redhat.com/pub/rhel/rel-eng/RHEL6.1-20110406.0/6.1/Server/x86_64/os/ 

virtio-win-prewhql-0.1.zip
libvirt-0.8.7-16.el6.x86_64
qemu-kvm-0.12.1.2-2.153.el6.x86_64
kernel-2.6.32-130.el6.x86_64

And now , the reproducible percentage should be 20% .

Does it work w/o hot plug?
I cleared the blocker flag since we cannot hold the release just for this.
Comment 7 Vadim Rozenfeld 2011-04-14 09:56:23 UTC 
Hot plug/hot unplug should work fine for non-system virtio drive.

Do you have a crash dump file?

It's not BSOD in WindowsXP guest, but have the qemu-kvm process killed . So we didn't get the crash dump file from the XP guest .

  without partition , hotplug/ hot unplug work fine .

Tried more than 50 times with the same kernel/qemu-kvm/libvirt/virtio-win
version and steps, tested both qcow2 and raw image, can not reproduce it.
So I will close it as WORKSFORME. Please reopen if it can reproduce again.

Thanks.
