Comprehensive guide to performance optimizations for gaming on virtual machines with KVM/QEMU and PCI passthrough
Article is under construction! Gaming on virtual machines – Preamble This guide describes performance optimizations for virtual machines (VM) with GPU passthrough which have gaming as their main use case scenario (don’t bother, straight to the config). In the beginning, when I started focusing on virtualized gaming, especially demanding online multiplayer games, I thought only […]
Fighting error 43 – Nvidia GPU in a virtual machine
The infamous error 43 is triggered by the Nvidia Windows driver, in case it recognizes the GPU is used inside a virtual machine with GPU passthrough. This means the driver won’t load correctly during the system startup leaving you with cumbersome 800 by 600 display resolution. An examination of the Windows Device Manager will unveil […]

Configuring Hugepages to use in a virtual machine
Hugepages are an optional step during the VM configuration; it increases the RAM performance of the virtual machine. The downside is that the RAM allocated to the hugepages can not be used in the horst system, even if the guest isn’t running. The minimum size should be not smaller then 4GB. Check if hugepages are […]
Different ethernet setups for virtual machines
Still in draft: – using bridge device * -> easiest, fastest and most convenient way, but requires wired connection. – using network tap – using host mode libvirt’s default setup where the VM host more or less acts like a NAT router for all the virtual machines running on it. This works out of the […]
