Just to make sure, this only affects the source side, and does not have
to be set on the destination (that is, the destination will
automatically handle incoming dirty bitmaps correctly without having to
tweak the knob first)?  Of course, libvirt will check that the
destination advertises the feature before enabling the knob on the
source (to avoid the case of the source sending something the
destination won't understand).
