Yes. If your machine type supports PCI hotplug then you can use the
netdev_add and device_add commands. This is equivalent to hotplugging a
NIC into a running machine.
I don't have exact syntax because I haven't tested it, but it should be
similar to using the -netdev tap,id=netdev0 -device e1000,netdev=netdev0
command-line option syntax.
