Hi, I've got a computer that I'm running debian 10 on with KVM. The machine is connected to a OpenWRT router which provides DHCP and DNS to the network, via a wifi link used for the host and an ethernet connection on eth1 used for a bridge
I've set this file up for the bridge in /etc/network/interfaces.d/br0 auto eth1 auto br0 iface br0 inet dhcp bridge_ports eth1 bridge_fd 0 bridge_stp off ifup br0 brought it up nicely and it got an IP address in the range I'd expect. So far so good. The only problem is now, I can't get any of the VM's I create to use this network. When creating a VM using Virtual Machine Manager, it gives me the option to specify shared device name for the network source. One of these is for a network I already created in virsh; <network> <name>host-bridge</name> <forward mode="bridge"/> <bridge name="br0"/> </network> However, if I set the network to either 'host-bridge' or br0 directly, the route is never set and I can never get a dhcp setting. I've checked ip_forward is set to 1. I'd just like to set it up this way, as it seems really inefficient to have a dhcp and then use difficult to remember static IP's everywhere. Thanks James
