[Xen-users] Upgrading from GPLPV drivers from 0.9.11/0.9.12 to 0.10.0.86

[Matthieu Patou <mat+Informatique.xen@xxxxxxxxx>]

Hello,

I finally manage to upgrade windows 2008 server from 0.9.1[12] to 
0.10.0.86 drivers.
For all my tests I started by doing a snapshot of my windows 2008 system 
disk and working with the snapshot instead of the live image ... it 
allow to be sure to be able to restart with a sane situation ....
I first tried the uninstall (with the .bat provided by james on his 
website) and then installing new drivers while after rebooting without 
/GPLPV.
At next reboots booting either with no flag or with  /NOGPLPV or /GPLPV 
always lead to blue screen with 0x07 error.
I noticed that when I rebooted with drivers 0.9.1x installed but without 
the GPLPV flags all xen devices but the xen pci where with a yellow 
question mark (which is logical).
So I in the device manager I suppressed the all that xen devices 
including the xen pci and always asked Windows to remove the driver as well.
Once it's finished I restarted the computer, run this part of the script
REM stop and remove shutdownmon service
net stop shutdownmon
"%ProgramFiles%\Xen PV Drivers\ShutdownMon.exe" -u

REM remove XEN from Program Files
rmdir /q /s "%ProgramFiles%\Xen PV Drivers"


and this one:
REG DELETE 
HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318} 
/v UpperFilters /f
REG DELETE 
HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318} 
/v UpperFilters /f
REG DELETE 
HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E97B-E325-11CE-BFC1-08002BE10318} 
/v UpperFilters /f
Then I installed the new drivers restarted 2 time in /NOGPLPV just in case.

Now I am enjoying windows 2008 server with up to date GPLPV drivers.
It seems that this version of drivers are quite good because I am able 
to get most of the native speed from the hard drives (which I wasn't 
able with 0.9.1x), the  only drawback is that cdrom isn't showing at all 
(like I reported already in XP).
HTH
Matthieu.
