Scripts and configs for my vfio setup
Current host-hardware configuration
- core i7 6500
- intel igp for the host
- 16 gb ddr4 (potentially upgrading to 32gb in the future)
- ssd with lvm for storage
- nvidia gtx970 for passthrough
- archlinux
- synergy for shared mouse/keyboard
Setup at the moment
- two monitors used for host when vm is not running, both connected to IGP
- one monitor of the two monitors is also connected to the gtx970
- when the guest starts, the left monitor on the host is disabled, switching to the gtx970
- the host desktop is moved to the right screen
- cpugovernor is set to performance
- synergy starts in client mode on the host, if the host is the server most games that capture the mouse wont work properly
- on shutdown the original host setup is restored
- the cpugovernor gets reset to powersave
- synergy is shutdown
The VM uses virtio for the network card, and virtio-scsi for storage
Memory for the guest is allocated with hugepages
Pitfalls
- Sound was not working due to a permission issue. Setting the user in
/etc/libvirt/qemu.confto my user fixed that - Creating a bridge with networkmanager was harder to figure out than plain netctl/bridgeutils/etc
- Error 43 on nvidia driver install, easy fix with hv_vendorid and kvm hiddin domain xml
