Yes & no. Yes, libvirt will support hotplug, but that's only actually
going to work for devices which are PCI based. eg virtio-serial and
virtio-console. You can't hotplug <serial> or <paralle> devices which
use the ISA bus, which is what Chris was trying todo here.

But that's just a QEMU limitation. If QEMU learns to hotplug a device
onto ISA bus, libvirt will allow it.
