Not at this time. The QEMU monitor interface doesn't provide sufficient functionality to be able todo this, because there's no way to pass have libvirt create & setup the TAP device, and then pass it to QEMU. The QEMU monitor needs to gain the ability to do SCM_RIGHTS to accept an open file handle before we can hotplug NICs in any useful manner.
