After the BSOD, the windows guest can't be login. so can't get crash dump file.
Comment 2 Paolo Bonzini 2011-02-23 16:08:29 UTC 
I don't know if it is a regression, but you're right it should be a blocker.

Hi Paolo,
I think it is not a regression bug, because when I test with xenpv-win-1.3.1-1.el5, it also BSOD after uninstall xenpv-win driver.
Comment 6 Paolo Bonzini 2011-02-28 18:05:59 UTC 
I'll build 1.3.4-3 with a working fix.
Comment 7 cshao 2011-03-04 03:16:11 UTC 
Test Version:
xenpv-win-1.3.4-5.el5
xen-3.0.3-123.el5
kernel-xen-2.6.18-245.el5

Test platform:
win2k3-32bit
win2k8-32bit
win2k8-64bit
win2k8R2

Test result:
Windows guest can reboot successful after uninstall xenpv-win driver, no BSOD.

So change the bug status to verified.
