Dear Weidong, Pasi, and Xen developers, The report from Andrew confirms my reports that Intel integrated graphics (IGD) VGA passthrough with Xen 4.0.1 and pv-ops dom0 kernel 2.6.32.21 is unstable. Please check the previous emails that I have sent to all of you. -- Yours sincerely, Mr. Teo En Ming (Zhang Enming) 张恩鸣 Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Citizenship: Singapore Citizen/Singaporean Alma Maters: [1] Singapore Polytechnic (Graduated 1998) [2] National University of Singapore (Graduated 2006) Facebook account: Teo En Ming (Zhang Enming) Facebook link: http://www.facebook.com/profile.php?id=100000750083982 Facebook photos: http://www.facebook.com/profile.php?id=100000750083982#!/profile.php?id=100000750083982&v=photos Facebook videos: http://www.facebook.com/profile.php?id=100000750083982&v=app_2392950137 Mobile Phone (Starhub pre-paid): +65-8369-2618 Windows Live Messenger: teoenming-at-hotmail.com Location: Bedok Reservoir Road, Singapore ZIP: 470103 My Open Letter (Plea for Medical Help/Assistance) to World Leaders (Updated 28 August 2010):- http://lists.mcs.anl.gov/pipermail/mpich-discuss/2010-August/007811.html http://mythtv.org/pipermail/mythtv-users/2010-August/295952.html http://archives.gentoo.org/gentoo-user/msg_f6a341d9623fda17880159b137c07335.xml Photo of Mr. Teo En Ming (Zhang Enming) 张恩鸣 of Singapore: http://i53.tinypic.com/207tamp.jpg On 09/20/2010 04:58 PM, Andrew Warkentin wrote: > I tried passing the integrated graphics adapter to the Windows domU, > and the monitor goes into standby when the domU is started.
