Do I need to make provisions for it (and if so, where) 4) If the TAP is needed, do I have to make , or does the guest make the TAP and set it up? > auto lo > iface lo inet loopback > > # The primary network interface > auto eth0 > > #make sure we don't get addresses on our raw device > iface eth0 inet manual > iface eth0 inet6 manual > > #set up bridge and give it a static ip > auto br0 > iface br0 inet static > address 192.168.1.2 > netmask 255.255.255.0 > network 192.168.1.0 > broadcast 192.168.1.255 > gateway 192.168.1.1 > bridge_ports eth0 > bridge_stp off > bridge_fd 0 > bridge_maxwait 0 > dns-nameservers 8.8.8.8 > > #allow autoconf for ipv6 > iface br0 inet6 auto > accept_ra 1Once that is correctly configured, you should be > able to use the bridge on new VM deployments with: > > virt-install --network bridge=br0 [...] That last line looks like you're not using TAP at all. Is that true? What goes between the square brackets?
