assigning a single IP to the guest with "typical" hosting provider
I have a server with a hosting company, Hetzner. The servers at this hosting company have a public IP, let's say, A.B.C.D/255.255.255.x. Additionally, one can order extra IPs like below: 1) additional subnet (let's say X.Y.Z.0 / 28) 2) single IP (let's say, E.F.G.H) With additional subnet, assigning the IP to libvirt guest is simple: - assign X.Y.Z.1 on the host - assign X.Y.Z.2

I saw that the others are experimenting in this topic, so I would like to present the results of my work and tests, perhaps it will be helpful to others. As the prototype I used a manual written by Daniel: https://www.berrange.com/posts/2013/08/12/running-a-full-fedora-os-inside-a-libvirt-lxc-guest/ After many
