Xen users - Jan 2013 - Xen 4.2.1. BSOD in Windows guests with VGA passthrough

Hello,

I configured xen with enabled passthrough primary VGA card (Intel Integrated 
grafphic controller HD 3000) and audio controller (Intel HD audio) to hvm 
guest.
I also installed GPLPV drivers to improve performance.
And it works for Windows XP (x86) and Windows 7 (x86_64).

But I get a BSOD, when I try to load a disk or network subsystem or start 
Windows 7 performance test.
Steps to reproduce
1) enable PCI passthrough and pass primary VGA card
2) Try to copy a large file (3G for example) over the network into guest. ( or 
try to install large application)
Symptoms:
1) A graphical artifacts appears
2) Then comes the BSOD and each time with different messages.

If VGA passthrough is off, there is no such problems.

Any ideas?

My xl info in xl_info.txt in attachment.

My xl dmesg in xl_dmesg.txt in attachment.

Domain 0 kernel configuraton in dom0.config.

Guest cfg is xl_hvm.cfg in attachment.
By the way /dev/mapper/oxen0 is opened LUKS partition

Thank you.

If this error only occurs during large network transfers have you tried
without GPLPV Drivers, or more specifically a non-PVHVM network adapter?

Probably unrelated, but why did you force HPET off?

Per Man Pages "Enables or disables HPET (High Precision Event Timer). This
option is enabled by default and you should usually omit it. It may be
necessary to disable the HPET in order to improve compatibility with guest
Operating Systems (X86 only)".

Can you supply your error logs (/var/logs/xen/), they might be helpful in
determining the cause of the crash.

Hello? thank you for answer.

It seems that this problem depends only on gfx_passthru=1 and VGA passthrough.
Everything works without problem if I remove VGA device from pci passthrough 
and set gfx_passthru=0.
>Probably unrelated, but why did you force HPET off?
If disabled HPET according to "...It may be necessary to disable the HPET
in
order to improve compatibility with guest Operating Systems (X86 only)".

It seems that it does not matter.

Log in attachment.
1) I downloaded JRE 6 for Windows without problem.
2) BSOD with MEMORY_MANAGMENT appeared during jre instalation.

I currentrly use GPLPV 356 version.

Thank you for advice.
I changed guest memory to 3G and got more stability, But BSOD comes again :-)
I changed guest memory to 2G and everthing become OK, even windows perfomance 
test.
It seems the less memory I provide to guest, the more stability I obtain.

It is painful for me to have 16G RAM and use only 2G. Do you know any solution 
to fix this issue?
