I just think of common scenarios like 'maintanace mode', where all VM should migrate to another host. A endless migrate task can make that fail.
For me, it is totally unclear what value I should set for 'max_downtime' to avoid that behavior?
We used to have a heuristic that said 'if an iteration transfers more
pages than the previous iteration, we've stopped converging'. Why
wouldn't that work?
Because it seems people agreed that mgmt tools would be the place for those heuristics.
Heuristics like number of pages, maybe. But since we don't export
iteration information, we can't expect management tools to stop the
guest if migration doesn't converge.
I suppose it could issue a 'stop' after some amount of time (constant *
memory size / bandwidth).
