Yes it is rational, and you're not the first to request it.
Unfortunately, we haven't yet taught 'virsh migrate' to support offline
migration, even though (or because?) it is dead simple to cobble
together yourself:

source$ virsh dumpxml $dom > file.xml
dest$ virsh define file.xml

optionally followed by
source$ virsh undefine $dom

Patches are welcome to make 'virsh migrate' automatically handle an
offline migration.
