Here is some more data for vfio-vga.
I have tried NVIDIA (MSI) GT610 and ATI (MSI) 7850 cards separately in
primary and secondary (to Cirrus) modes. The ATI can boot as primary in VGA
mode, but installing Catalyst causes the VM to reboot repeatedly on bootup.
The NVIDIA doesn't get past POST as pr

Hi all,
Perfect timing from my perspective, thanks Alex!
I spent the better part of the weekend testing your branches on a new system
I just put together for this purpose, results below..

A few notes for anyone trying this...
* I recommend the q35 machine type and using the default config
file found in the docs directory. This means your command line
should include:
-M q35 -nodefconfig -readconfig /path/to/qemu.git/docs/q35-chipset.cfg

Hi folks,
A number of people have been trying VFIO's VGA support, a few have even
been successful. Resetting devices has been a problem and makes it
very, very difficult to really use VGA assignment effectively. The code
in the branches below attempts to address this. Discrete graphics
