KVM: How to set up a private network between guests and the host
I'm running KVM on my Ubuntu box, and would like the host and guests to share a private network that is not attached to Internet (i.e. not the default NAT setup that comes out-of-the box with libvirt).
The default NAT'ed setup works, except that it connects the guests to the internet, and I guess I could simply block internet related traffic in the firewall, but I'm sure there are smarter ways of doing this. Anyone got tips on how to accomplish this?
