[Xen-devel] [Xen VGA Passthrough] Cannot Complete All 3dmark Tests in Windows 8 HVM domU

[Teo En Ming <singapore.mr.teo.en.ming@xxxxxxxxx>]

Hi,

I have got VGA Passthrough working with AMD Radeon HD 6450.

I am able to complete all 3dmark basic edition v1.3.708 tests in Windows 
7 HVM domU but I cannot complete all 3dmark tests in Windows 8 HVM domU. 
In Windows 8 HVM domU, the monitor would turn blank at Sky Diver demo in 
the 3dmark test.
In *bare-metal* Windows 8.1, I am able to complete all 3dmark tests. 
Should I upgrade Windows 8 HVM domU to Windows 8.1? Do you think I can 
complete all 3dmark tests after upgrading Windows 8 HVM domU to Windows 8.1?
Finally, I cannot start Unigine Heaven Benchmark 4.0 in Windows 8 HVM 
domU but I can run Unigine Heaven Benchmark 4.0 in Windows 7 HVM domU. 
Is Unigine Heaven Benchmark 4.0 incompatible with Windows 8?
Please advise.

Yours sincerely,
