They have to be marked as 'live-migration-capable' in the mapping
config, and the driver and qemu must support it.
For the gui checks, we now return the whole object of the mapped
resources, which includes info like the name and if it's marked as
live-migration capable. (while deprecating the old 'mapped-resource'
return value, since that returns strictly less information)
