[libvirt] Re: SOLVED kvm networking on debian unstable
The solution is, to delete
/etc/udev/rules.d/70-persistent-net.rules
in the guest and reboot. This is an autogenerated file, which stores the
mapping of MAC adresses to interface names. Since my MAC address changed, the
interface wasn't automatically added anymore.
