Review comment:
@nvazquez, I think if we put this condition in line 1300 itself, then it
would maintain the old flow. Something like this in line 1300: if
(vos.isEmpty() && vosMigrating.isEmpty() && failedMigratedVms.isEmpty()) {...}.
And we can put this message(debug purpose) for all kind of failures, where
resource state would transit to UnableToMigrate.
