Hello, This is to announce that, we have been able to pass-through a ATI Radeon RV370 FireGL V3100 to Ubuntu VM. This card was attached to a separate monitor, after passing-through the Keyboard and Mouse everything worked as normal. The changes we made are very less, mostly disabling default QEMU VGA. But there are few problems that we are still working on 1. The display on the monitor, probably only appears after the KMS is enabled. It does not display the grub menu and booting log. 2. If we intermix the QEMU default devices like Network or another VGA. The VM does not work properly. We could see IO_PAGE_FAULT events being logged in the system messages. I guess this is happening because of some memory region conflicts. But if we pass-through a Network device and a GPU card to VM it works perfectly. Till now we only observed problem when QEMU default devices were intermixed with the pass-through ATI card. 3. Windows does not work at all. No display, lots of IO_PAGE_FAULT events. 4. The card that we used is somewhat old one. "André Weidemann" <Andre.Weidemann@xxxxxx> is trying to pass-through a relatively new ATI card. We will have results very soon. 5. Nvidia or Intel IGD cards have not been tested. Currently I am focusing on solving problem 2 and 1. I am very new to KVM and QEMU, I will appreciate if someone can help me or point me to a correct direction. Once these problems are solved I will send the patches for comments on this mailing list.
