Re: [Xen-devel] Re: [Xen-users] VGA passthrough problems with GeForce GTS 250 and P7Q57-M DO (also: LGA1156 boards with working VT-d)

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

Dear Pasi,

Were instability issues with Intel integrated graphics (IGD) VGA 
passthrough in Xen 4.0.1 fixed with Xen 4.0.2-rc-pre?
Thank you very much.

Yes. Only Windows XP HVM domU is crashing.

No. I was still able to access dom0 through Xen serial console after 
Windows XP HVM domU has crashed. I was able to execute the reboot 
command in dom0.

No. I have to do a hard reboot of dom0.
