Xen users - Sep 2009 - uninstalling GplPv 0.9.12-pre4 ends in bluescreen

Hello,

I need some advice how to completely remove the gplpv drivers from my windows 
2003 server. I just tried the uninstaller provided by James Harper from his 
post http://lists.xensource.com/archives/html/xen-users/2009-05/msg00555.html 
but I end up in a bluescreen after reboot and stuck at this point. 
As I used a lvm snapshot to test this uninstall process before, my system 
isn''t broken in real. I can just create a new snapshot and try it again
until
it works. But I really need to remove these drivers so that I can boot again 
with the ioemu mode.

Any help would be appreciated!

Thanks,
Martin

What BSoD are you getting? Is it 0x7B?

Can you re-run the 0.9.x uninstaller and then open regedit and search
for any reference to xenhide (just in HKLM/System/CurrentControlSet) and
tell me what keys you find it in?

Sure:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E97D-E325-11CE-
BFC1-08002BE10318}
-> UpperFilters = XenHide
.. and serveral other key/values

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ACPI_HAL\PNP0C08\0\Control
-> ActiveService = XenHide
.. and serveral other key/values

Thats all

Delete the Upperfilters value. Let me know if it exists in any othe
''UpperFilters'' too and I''ll add them to the uninstall
script.

If it works let me know and I''ll upload the updated uninstall script.

Thanks

Okay, but do I need to delete the whole key and its subkeys (there a serveral 
subkeys named 0000 to 0023) or only the "UpperFilters" REG_MULTI_SZ
Key/Value?

Okay, after deleting just the ''UpperFilters'' value and
rebooting afterwards
all is working fine.
I was able to start Windows again without the gplpv driver.

Thanks a lot for your help!

I confirm that I have experienced the exact same issue and that  
removing manually the key you indicate

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E97D- 
E325-11CE-BFC1-08002BE10318}\UpperFilters

have solved it
