Hi,

I am trying to VGA passthrough Intel HD Graphics 4600 IGD with 
Xen-unstable 4.4 changeset 27214 and Linux kernel 3.10.0 but was not 
successful.

Details are as follows:

teo-en-ming@intel-core-i5-4430-desktop:~$ sudo xl info

====================================================================================

Linux intel-core-i5-4430-desktop 3.10.0-xen-teo.en.ming-sgp #1 SMP Sat

=====================================================================================================================

teo-en-ming@intel-core-i5-4430-desktop:/var/log/xen$ cat 
qemu-dm-Windows8.log
qemu-system-i386: -gfx_passthru: invalid option

=====================================================================================================================

It seems that "gfx_passthru" is no longer a valid option. May I know the 
new name it's being called now? Or does it mean that Xen-unstable 4.4 
changeset 27214 does not support vga passthrough any more?
