If you don't use virt-manager/virt-install, then basically it's all libvirt does: create virtbr0. If you're familiar enough with manual bridge and NAT setup, you could just create it manually, which would involve: - create a bridge with is not connected to any physical host - create NAT MASQUARADE rule for any traffic coming from that bridge - (optional) run dnsmasq to provide DHCP and DNS With that kind of setup (either manual or created by libvirt) you can simply use bridge networking in Xen as usual, and it doesn't matter whether your uplink is already bridged or not. And the same bridge+NAT setup can be used for other virtualization setup as well (For example, I'm using libvirt to create a bridge on my Virtualbox setup, which Virtulbox uses later as bridged networking) -- Fajar _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
