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

["Zytaruk, Kelly" <Kelly.Zytaruk@xxxxxxx>]

Hi Teo,

Unfortunately it is very difficult to analyze what went wrong with a computer 
"freeze" without a debugger attached to the session.  Do you have any 
experience with Windbg and passing a 1394 connection into the VM?

With the Win8 page fault in atikmdag.sys there would have been a .dmp file 
created and we could have looked at that to see where it faulted.

My first recommendation would be to try not passing the graphics adapter in as 
passthru and see if you can get the VM up and running without the adapter.  
This would help to narrow down whether the issue could possibly be related to 
the Radeon driver or not.  Also please ensure that you are using the latest 
release version of our driver as it would be up to date with any bug fixes.

I myself am still using Win7  in the DomU and have not yet experimented with 
Win8.1.  I find Win7 very stable and it has not given me any problems as a 
guest OS.

Thanks,
Kelly
