If you're referring to QEMU then yes, you can dynamically create all of
character devices (to connect to the vhost-user server), network devices
(to create a vhost-user client) and NICs (that peer with the vhost-user
server).

If you're using libvirt to run QEMU, you can in fact invoke a single
"virsh attach-device" command to handle all three steps.

Thanks,
