When using 'virsh attach-device' to hotplug an unsupported console type
into a qemu guest, the attachment will erroneously allows the

types are used for a running guest. NB, Although a guest can be defined
with an improper target, startup will cause failure.

This should be a goto cleanup;
I can clean this up; however, will it be necessary given patch 2/2?
