Windows drivers works only if KVM will bypass to Windows both AMD devices.Р”Р„MD Vega 56/64 is unable to initialize itself after Guest host shutdown/reboot, because drivers left card in 'garbage' state. Click Apply.Р”Р„MD cards have 2 devices on PCIe bus -> one video output and another is HDMI output. Edit virtual image, click Add Hardware, select AMD Ati Vega 64 and AMD Ati device. Unfortunately the implementation of ACS varies greatly between different CPU or chip-set models.Р”Р‡ILE /etc/modprobe.d/nf options vfio-pci ids=1002:687f,1002:aaf8 Libvirt WindowsР”В¬reate Windows 10 as usual via libvirt manager. ACS features are implemented within the CPU and the chipset. ACS is able to tell whether or not these peer-to-peer transactions are possible between any two or more devices, and can disable them. That is where PCI Access Control Services (ACS) are called to the rescue. Moreover, the PCI-Express (PCIe) specifications allow PCIe devices to communicate with each other directly, called peer-to-peer transactions, thereby escaping the IOMMU. But in practice this is often not the case. In an ideal world, every device has its own IOVA address space and no two devices share the same IOVA. In other words, it translates the IOVA into a real physical address. The IOMMU maps a device-visible virtual address ( I/O virtual address or IOVA) to a physical memory address. IOMMU РІР‚вЂњ or inputРІР‚вЂњoutput memory management unit РІР‚вЂњ is a memory management unit (MMU) that connects a direct-memory-accessРІР‚вЂњcapable (DMA-capable) I/O bus to the main memory. Some EFI doesn't have IOMMU configuration settings IOMMU Go into BIOS (EFI) settings and turn on VT-d and IOMMU support. Optional but recommended: Additional monitor, keyboard and mouse.

(You can in theory run your computer headless through SSH or a serial console, but it might not work and you risk locking yourself away from your computer if you do so). At least two GPUs: one for your physical OS, another for your VM.Chances are that your motherboard will support it if it's from 2013 or newer, but make sure to check since this is a niche technology and some manufacturers may save costs by axing it from their motherboards or delivering a defective implementation (such as Gigabyte's 2015-2016 series) simply because NORPs never use it.

To find this out, check in your motherboard's BIOS configuration for an option to enable IOMMU or something similar.
