[one-users] QEMU-KVM problem: Error deploying VM on a Public Network

My pleasure.
I think the problem is that you have to setup brdiged network on the
host properlly.
Instead of using eth0 as the network device in the VM, you should use br0.
You can google how to setup bridged network for virtualization for
your Linux distribution.
Hope this helps.
