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:
No surprise to me: this feature has been implemented for the lxc driver and
the qemu driver doesn't care about these config bits.
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

link up, it this libvirtd, qemu, or do I need to write a qemu-ifup
script?
Qemu has the possibility to set up the ip address directly only with -net nic.
For a tap device, this has to be handled by qemu-ifup / qemu-ifdown.
