[libvirt] networking with VMs on two nodes

[Andreas Rittershofer]

I have two nodes and on each several virtual machines  running under  
KVM/qemu. I've set up the default-network on each node and so I can:

1.) ping from host do guest
2.) ping from guest to host
3.) ping from guest tu guest


But all this is only possibe on each node by itself.

What I need now is network connection between a VM on node 1 to  
another VM on node 2. How to setup this?

When both nodes are fine every node runs a few guests. But when one  
node goes down, all guests have to be run on the remaining node.
