I would like to use the virDomainMigrateSetMaxDowntime but I'm a
bit
confused about how to use it.
If I try to set the downtime before I call domain.migrate(), I get the
error "domain is not being migrated". But I cannot call it afterwards
because domain.migrate() does not return until the migration has
completed.
the API is intended to prevent the migration from lasting forever if
the memory of source domain is dirtying so quickly that QEMU does
not have time todo the final completion switchover, but not to
guarantee the migration will be finished more quickly.
so yes, domain.migration will not return till it's finished.
