I use 4 different networks (1 for server-host) and one for each of the 3 vms. Those 4 networks are completely shielded from each other and MUST NOT have access to one another.
What im trying to accomplish is on the host system, just to give the host itself access to the first nic, the other 3 must not be visible (or active) so the host can remain within its network and is completely firewalled.
the 3 vms use 3 independent DMZ networks and must not access the main network at all costs. the same goes for the host, it may not be accessed in any way from one of the dmz's.
How do i need to setup my network in ubuntu server with kvm?
