When I tried to access the Mint desktop from a teamviewer client. Did 'lspci' and found that the VGA adapter was 'Cirrus Logic GD 5446'. I've googled it and Debian/Ubuntu seems to have very slow VESA drivers in the latest releases. I then opened the terminal and did 'lspci' and found that the VGA adapter was 'Cirrus Logic GD 5446'. I then shut down the KVM and went to the Proxmox Virtual Machine configuration under Options and changed the 'Video Graphic Adapter' from 'Default' to 'Standard VGA'. Hello nbhs and all, I have tried serval days to pass-through my Nvidia GT640 and AMD HD7750 GPU to Windows7 KVM guest but with no succeed. I followed all steps in the first post and now I could pass-through GPU device to Windows 7 VM but still has the follow issues. 1.VM with AMD HD7750 GPU, win7 start up BSOD with 0x00000116 on atikmpag.sys same as ilya80 post at the solution of change 'clear_emulator_capabilities = 0' on qemu.conf take no effect. 2.VM with Nvidia GT640 GPU, both vm and host hangup when vm OS booting to the twinkling mircorsoft windows logo. 3.there is no display on Qemu's Window,need to connect pass-throughed GPU's DVI port to display VM desktop. For issue 1 and 2,enter VM on 'Safe Mode' will be OK, but without graphics driver thus no hardware acceleration. Cirrus Logic AustinCould you please help me to check my issue.

I would recommend (1) don't pass the audio part 1:00.1, (2) in safe mode uninstall the AMD drivers; then after that presumably you can boot windows with the generic VGA driver (and you won't have the atimpag.sys error because there won't be an ati driver). (3) then reinstall only the graphics driver, not the CCC. When you install the drivers, there is an option to do that. You will still have accelerated graphics, just not the tuning available with the CCC. Anyway, that worked for me with my HD7970. Hi, nbhs and all! I would like to share my configuration of my sort of wannabe 'All-in-One' KVM VFIO on Arch Linux. Using all nbhs' ingredients (kernel 3.14), I have successfully passed through my GeForce GTX 770 and IBM M1015 to my KVM guests. Using this configuration I can also natively boot to both Linux Mint Debian Edition (for whole disk backup of Arch Linux disk) and to Windows 7 when I need the true bare metal performance (Metro: Last Light +/-4 FPS increase on Windows 7 native). 3DMark Results Bare Metal: KVM Guest: Any idea on how to make my CPU recognized by 3DMark when on KVM Guest?

Cirrus Logic 5446 Driver Linux Mint SystemThanks for pointing that, I was having difficulties on applying the new QEMU network parameters thus ended up using the ones that I have mentioned in my post. Will definitely try that. In my case, my bridge device is called br0, so I assume your brlan is my br0? I also found this slide, probably will try to enable/disable the kvm_intel module parameters and see if it would increase my benchmarks: vpid, flexpriority, and ept.
