Trying to use Xen PV drivers for Windows (Release 0.5.0)

[Igor Chubin <igor@chub.in>]

Hello James,


Thank you for you work, 
it'r really interesting and really useful.

No about my experiments and problems.


I have tried to install your drivers into Windows XP.
I have downloaded the drivers from [1], 
unzipped it and installed it as describe in 
the INSTALL.txt.

The installation process was exactly as you have described
in the INSTALL.txt file. No any errors.

After that I have modified boot.ini (added new boot variant
with the /gplpv key) and rebooted the system.

I have tried to boot using the second boot option in the boot menu
(/gplpv) and have got blue screen of death
(it appeared just after a second as a I have pressed enter in
the boot menu).

I have tried to boot using the first boot option in the boot menu
(without /gplpv). The system have booted without any problem.
After that I have tried to make hot block-attach to
the domain.

sudo lvcreate -n winpv -L 2G /dev/MAIN
sudo xm block-attach 13 phy:/dev/MAIN/winpv /dev/hdd w

(where 13 is the id of the windows domain)


Just after I issue the command Windows goes into blue screen of
death. There are the message on th screen:

DRIVER_IRQL_NOT_LESS_OR_EQUAL
....
Technical information:
*** STOP: .....

***    xenvbd.sys  - Address FC769C787 base at ....


You can take a look at the shot of the screen with the error here [2].


I have tried to change the domain configuration.
I played with acpi, apic and pae parameters.
Domain didn't want to boot in any combination except 

apic=1
acpi=1
pae=1

This one was used before I've started to change apic/acpi/pae
parameters. At least I've reverted back to it.

Also I have tried to disable CDROM in the pv domain.
Without success.



Thank you for your any ideas.
And once again thank you for you work
