Virtualization

Virtualization scripts and config for Arch Linux hosts and Win 10 guests using KVM, QEMU, VFIO and OVMF.

Hardware

  • OS: Arch Linux running linux-vfio kernel.
  • CPU: Intel i5 6600K.
  • GPU: Gigabyte Radeon RX 460.
  • Mobo: Asus Z170i.
  • Storage: Samsung 850 EVO 500GB.
  • Memory: 16GB Corsair DDR4.
  • Monitor: LG 23EA63.

Software

  • linux-vfio
  • qemu or qemu-git (recommended)
  • virtio-win
  • ovmf

Notes

  • You can easy simlink the config files using stow -t / boot mkinitcpio and then mkinitcpio -p linux-vfio.
  • -smp cores=4 - guest might utilize only one core otherwise.
  • -soundhw ac97 - I’m passing mobo audio thus ac97. Download, unzip and install the Realtek AC97 drivers within a guest.
  • Use virtio drivers for both block devices and network. For example, the ping went down from 250 to 50.
  • Mouse and keyboard passthrough solved the terrible lag problem which was present in emulation mode.
  • Make sure virtualization is supported and enabled in your firmware (UEFI). The option was hidden in a submenu in my case.
  • As trivial as it sounds, check your cables.
  • Be patient - it took more than 10 minutes for the guest to recognize the GPU.
