The execution of scripts does not currently work, since we started using libcap-ng
to drop all capabilities on QEMU. It will be denied any access to create TAP devices
even when running as rot. You need to switch to bridge/network type interfaces which
makes libvirt configure the TAP device on QEMU's behalf.
