On second review, this does not look correct. The VM continues to run

this is the whole point of 'live' migration.

The reason for the 'cont' command is that the migrate operation always stops the VM at the end of the migration. So the cont command is always necessary.

The semantics of virDomainDumpCore (as defined by the current&  only
impl in the Xen driver), as that the core dump operation should be
non-live.

Actually that was done on purpose. Should I prepare a v3 doing a stop before the migration, and then work out how to implement the flag?
