following ubuntu guide on kvm, I've a test server up and running at this ip address 192.168.0.210 (netmask 255.255.255.0). The virtual machine (same as host ubuntu 11 server) use dhcp but has a specific ip 192.168.122.99. The host (already in bridge with guest) can access guest but for other nodes it's impossible! I've created a new virtual ip on the host 192.168.0.11 and trying to route all requests made to 192.168.122.99 (guest) to this ip, but it fails. I've followed this guide: https://help.ubuntu.com/community/KVM/Networking (paragraph IP Aliases).
Anyone can help?
