Re: [libvirt-users] Using libvirt with a preexisting network infrastructure

I have a server running Ubuntu natty (libvirt 0.8.8) with separate ethernet interfaces. I have created an unnumbered bridge for each interface, these are connected to an already established network infrastructure, with preexisting DHCP and DNS services. I would like to handle *establishment* of these bridges outside libvirt (via /etc/network/interfaces), but still have them defined as networks within libvirt. So, libvirt shall not *configure* the bridges, just be aware of their existence and connect each VM to its configured bridge. This way I can use virt-manager/libvirt to connect my virtual hosts to the correct network. The libvirt commands net-start, net-destroy would become no-ops. It seems that libvirt is geared towards handling all network configuration itself, but I do not need help from libvirt for establishing the bridges, DHCP and DNS.
