Hi, Is it possible to setup layer2 tunnels between guests across hosts? Using vrbr? -- i.e the Guest is unaware.

On Host 1: guest (a) --- vrbr0 ------- | | On Host 2: | guest(b) -- vrbr0 ------

Has there been any work done around it?

There's no direct support for that in libvirt's network definitions, but it would be a nice addition. Patches are always welcome (in this case you would probably want to send a proposal for the XML changes for the network definition to libvir-list first before spending any time writing code).
