On my own system (Z10PE-D8) I have passed three GPUs but was using the internal video for the host.

If so...<br>
Setting BusID parameter in xorg.conf should help starting any non primary GPU.<br>
Whatever the host bios outputs via GTX980 shouldn't worry you much.</p>

<br><div dir="ltr">So I am testing a Supermircro X10DRi board with a Strix GTX980 GPUs. The CPUs are dual Intel Xeon E5-2630v3. The CPU's do not have built in graphics but there is a video source on the mainboard. A ASPEED AST2400 BMC. It is the crappy AST2400 that I am using for the host video. <br><br>When I leave this facility the owners of this machine plan on later dropping in a 2ed identical GTX980 GPU for passthough. Hopefully Alex's vfio-pci-override-vga.sh can deal with that.<br><br>The host machine is using BIOS not UEFI to boot. The guest is using libvirt, EDK2, qemu2.5, virt-manager and Linux 4.1.6 on Debian testing. The single Windows10 guest and GPU works flawless. <br><br>The problem<br><br>The AST2400 video chip sucks. I would like to drop in a cheapo Nvidia GF210 to deal with the host graphics. This is not a EFI GPU but the host is using BIOS so I would think this is not an issue. I instruct BIOS to use external video. The GTX980 is being bound to vfio-pci at init-top or as early as possible. <br><br>Unfortunately I am not able to get any video out. It is as if both GPU's want to be boot-vga. I was informed in IRC that you must use a GeForce GTX980 as the boot GPU. Is that true?<br></div>
