Re: [libvirt] some questions about libvirt features and limitations

>I'm not sure - it depends what you're doing with the TAP device on the >host side of things ? The project I'm working on is an information system simulator. So I need virtual machines and virtual networks. I plan to use libvirt to provide the virtual machines, but even though I know libvirt provides virtual network facilities, the ones we developed are more adequate to what we need. So I need a way to "bridge" the network frames coming from the virtual machines into our "virtual networks". The way we do that using our current setup is by "sniffing" all traffic from TAP interface (that each corresponds to an "ethX" interface inside a guest) and injecting those frames inside our "virtual networks" to have those frames routed where necessary. So what I need is a TAP for each ethernet interface in each guest, and that's it. No bridge, no NAT. Just a one-to-one correspondence of guest "ethX" interfaces to host TAP interfaces. It seems to be what libvirt provides, but it always comes with a bridge. Is there a way to get the TAP without the bridge ?
