Does H110 motherboard and i3 -6100 support VT-d/iommu mode?
I am trying to build a PC with H110 mobo and i3 - 6100. I want to run Ubuntu as host and Windows as a VM with Integrated Graphics pass through. While the Intel site mentions for VT-d support, I'm not sure whether my mobo will support it?

Virtual machine does not seem to detect my GPU as 'primary'
If I enable a cirrus gpu this way : '-vga cirrus' while passing through my GPU, the cirrus display will be stuck at starting windows and the GPU will display windows properly. And if I put not vga display at all, '-vga none', then the GPU display will be stuck at starting windows. Also, with both ac...
If I enable a cirrus gpu this way : '-vga cirrus' while passing through my GPU, the cirrus display will be stuck at starting windows and the GPU will display windows properly. And if I put not vga display at all, '-vga none', then the GPU display will be stuck at starting windows. Also, with both activated, vnc only display the cirrus display and by no mean wants to display the GPU display. Sorry if it's confusing, I'm doing my best. So I'm thinking that my dedicated GPU is not set as primary by the bios or windows 7 itself, and I wonder how I could get through that ? On Windows 10, there was no such issue and everything worked perfectly, just that the OS sucks. Also, the host is running Gentoo GNU/Linux. Here is my QEMU script : #!/bin/bash export QEMU_AUDIO_DRV=sdl export QEMU_SDL_SAMPLES=2048 # Windows 7 Virtual Machine - Aimed at playing video games, using GPU Passthrough sudo vfio-bind 0000:01:00.0 0000:01:00.1 sudo qemu-system-x86_64 -enable-kvm -m 8192 \ -bios /usr/share/edk2-ovmf/OVMF.fd \ -cpu host,kvm=off \ -smp 8,sockets=1,cores=4,threads=2 \ -net nic,model=virtio \ -net user \ -rtc base=utc \ -vga none \ -device vfio-pci,host=01:00.0 \ -device vfio-pci,host=01:00.1 \ \ -drive file=/storage/sshd/vm/windows.img,index=0,media=disk,format=raw,cache=none \ -cdrom /storage/sshd/download/virtio.iso \

QEMU 2.8.0-r1 with vfio VGA passthrough on Gentoo 4.8.17-hardened-r2 hangs on Radeon RX 480 reset
I have Gentoo 4.8.17-hardened-r2 compiled for AMD64 running on an AMD FX 8350 CPU with an Asus M5A99X EVO R2.0 motherboard, and I have a QEMU 2.8.0-r1 VM with vfio PCI passthrough to an Asus AMD Radeon RX 480 DUAL video card, using Windows 10 Anniversary Edition as guest OS. Whenever my guest OS tri...
I have Gentoo 4.8.17-hardened-r2 compiled for AMD64 running on an AMD FX 8350 CPU with an Asus M5A99X EVO R2.0 motherboard, and I have a QEMU 2.8.0-r1 VM with vfio PCI passthrough to an Asus AMD Radeon RX 480 DUAL video card, using Windows 10 Anniversary Edition as guest OS. Whenever my guest OS tries to do what I believe is a GPU disconnection, my entire VM hangs and keeps eating all the CPU cores I have assigned to it. This means I have to do many convoluted workarounds to install my display drivers, which happens rather often because Windows 10's rolling release model also happens to include the latest Radeon drivers. Recently I attempted to change my simulated motherboard from default to Q35 hoping to take advantage of the better PCIE support, and this resulted in a situation where I cannot work around this issue anymore and ended up forcefully having to at least find out why QEMU hangs when Windows 10 disconnects from my GPU.
