What's the difference between NAT and host-only? I assume that in this context NAT means Network Address Translation, i.e. the host acts as a firewall and does NATting. The software I'm using is libvirt 0.7.0. I also see that from a VM I can ping the host's virtual interface, i.e. the IF on the virtual network. I can also ping its physical IF, which is on a separate network. > > Richard > > On Thursday, June 17, 2010 18:32:17 Charles Curley > <charlescur...@charlescurley.com> wrote: > > I have several VMs on a Ubuntu 9.10 host, and they have networking > > set up.
