Another way to reproduce it :

1.Start winxp Guest in RHEVM
2.install virtio-win-prewhql-59 in the guest 
3.stop RHEV-Agent Service in the guset 
4.ransferring data from guest to host 
cat 1.bat
:start
copy 1.txt \\.\Global\.\com.redhat.rhevm.vdsm
5. After 10 mins ,stop vdsmd service on the host
Comment 8 Mike Cao 2013-06-06 23:12:18 EDT 
Re-Test this issue on virito-win-prwehql-62 & virtio-win-prewhql-59

Steps same as comment #0

Actual Results:
Guest could shutdown sccessfully ,Can not reproduce the original issue both on build 59 & build 62

Move this bug to VERIFIED as the original issue has gone ,reopen it if QE hit this issue again
