[ClusterLabs] Gracefully Failing Live Migrations

Sometimes I've tried to move a resource from one node to another, and it
migrates live without a problem.  Other times I get

> Failed Resource Actions:
> * vm_myvm_migrate_to_0 on node1 'unknown error' (1): call=102,
> status=complete, exitreason='myvm: live migration to node2 failed: 1',
>     last-rc-change='Sat Jan 13 09:13:31 2024', queued=1ms, exec=35874ms

And I find out the live part of the migration failed, when the vm reboots
and an (albeit minor) outage occurs.

Is there a way to configure pacemaker, so that if it is unable to migrate
live it simply does not migrate at all?
