Dear Weidong and Pasi,

Please re-visit the Xen 4 Intel integrated graphics (IGD) VGA passthrough case of Tang-Hsun Tu (涂堂訓) on 22nd July 2010 at the following link.

http://www.mailinglistarchive.com/html/xen-devel@xxxxxxxxxxxxxxxxxxx/2010-07/msg01147.html

Apparently, the problems both of us have encountered in Xen 4 VGA passthrough are very similar.

Please watch my Youtube video on Intel IGD VGA Passthrough with Xen 4.0.1-RELEASE, pv-ops dom0 kernel 2.6.32.21, and Windows XP HVM again. The link is provided below.

Could we work together to resolve the stability issues in Xen 4.0.1 Intel integrated graphics (IGD) VGA passthrough to Windows operating system HVM virtual machine?

Thank you very much.

I have also tried booting Xen 4.0.1 hypervisor and pv-ops dom0 kernel 2.6.32.21 and then launch Windows XP HVM domU with-OUT VGA passthrough from within X Windowing Server (GNOME Desktop Environment). The guest operating system (WinXP HVM) in this case is perfectly stable and doesn't crash.

There could be stability issues with the Intel integrated graphics (IGD) VGA passthrough code in Xen 4.0.1. I have noticed that the screen/monitor tends to garbage out within 2 minutes after Windows XP HVM domU has booted up (with VGA passthrough enabled).

Thank you.
