Switching between drivers unreliable #854
Description
I've been testing #835 and that means switching between qemu and libvirt here.
I've now run into:
cze 24 13:45:22 michal-laptop dnsmasq[29705]: unknown interface mpqemubr0
cze 24 13:45:22 michal-laptop dnsmasq[29705]: FAILED to start up

dnsmasq: unknown interface mpqemubr0
# however
$ ip addr show dev mpqemubr0
27: mpqemubr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000

valid_lft forever preferred_lft forever
inet6 fe80::5054:ff:fe7b:9d53/64 scope link
valid_lft forever preferred_lft forever
I have a leftover libvirt interface, too, which is likely to blame:
$ ip addr show dev mpvirtbr0
20: mpvirtbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether 52:54:00:61:b7:7c brd ff:ff:ff:ff:ff:ff
