libvirtd running inside docker

About

Running libvirtd inside of a docker is a bit of a challenge and i didn't find any existing images. It requires a system with kvm and tun support, but this should be avalible on most of linux distro. If running inside virtualization, you must make sure nested virtualization is enabled. This image starts libvirtd listening on unix socket, as well as listening locally. To access you will need to share volume with sock, or much better soltuion is to connect over tcp.

This image is based on this gist: https://gist.github.com/kosyfrances/f8ffd9b76ff6285d60d1b1671c2aa8f6

Running

docker run \
  -v /sys/fs/cgroup:/sys/fs/cgroup:rw --privileged ghcr.io/xtruder/libvirtd:latest
