Hi all, I've been playing with the recently added support for adding ips and routes to a type"ethernet" kind of device. My goal is to get rid of bridging and use host routes (/32) combined with Bird for a pure layer3 setup. Something similar to what https://www.projectcalico.org/ is doing Instead of p2p addresses with peers they use device routes (ip route add 192.168.0.1/32 dev vnet0) combined with static arp entries. I am a bit stuck though. I've created the vm with a tap device: <interface type='ethernet'> <mac address='00:1a:4a:1b:d9:cc'/> <model type='virtio'/> <rom bar="off"/> <source> <ip address='192.168.42.41' family='ipv4' peer='192.168.42.42' prefix='32'/> <route family='ipv4' address='192.168.100.0' prefix='24' gateway='192.168.42.42'/> </source> </interface> After starting, the link stays down and no ips or routes are being created: root@test1: ~# ip link show dev vnet0 15: vnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether fe:1a:4a:1b:d9:cc brd ff:ff:ff:ff:ff:ff root@test1: ~# ip route show default via 10.10.5.1 dev br1010 10.10.5.0/24 dev br1010 proto kernel scope link src 10.10.5.2 I feel like I'm missing a step. Who is responsible for setting the link up, it this libvirtd, qemu, or do I need to write a qemu-ifup script? Any help is greatly appreciated. Kind regards, Ruben Kerkhof
