Nice day.

Throughout the year, does not go correctly configure VGA passthrough
Here, we show how to do it even on the one video card.

I have:
Ubuntu 10.10 Server
Kernel Jeremy
Xen 4.1.2 (4.2 untable freeze vm)

Windows7 (32 & 64 in testsigning mode)
Pv driver (debug version 357)

If I add in the config gfx_passthru = 1 and boot from any HD device - after pciback disable the device - graphics card is completely disconnected to reboot

If it is secondary - there is no loading system - qemu shows its proprietary information.

If I shipped with the PCI card (no PCI-E) and it is the primary - I see right on the screen qemu boot screen and try to boot from a block device. Then the video card crashes.

How to make sure that each of the ATI HD cards showed qemu boot screen and start DomU after xm create?
