Yes, so don't do that. As I understand it:
(1) if you don't run QEMU with the exact same command line
and config at both ends then migration won't work
(2) we don't guarantee to detect and cleanly fail if you
don't do (1)
It would probably be nice if we did detect config mismatches,
but that seems to me like a problem we should be addressing
more globally than just for one particular config item for
one particular target...
