Re: [Xen-users] Re: [Xen-devel] Requesting Assistance from Intel Engineers on Intel Integrated Graphics (IGD) VGA Passthrough for Xen 4.0.1-RELEASE and pv-ops dom0 kernel 2.6.32.x

["Mr. Teo En Ming (Zhang Enming) 张恩鸣 of Singapore" <space.time.universe@xxxxxxxxx>]

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.
