I am not sure if this is a hack. drbdmanage does not know when a VM is
migrated, but this information can be used to make it more safe by
only temporarily enable two primaries.

AFAIK sheepdog has a similar feature, called vdi locking, so maybe it makes
sense to extend our storage API with additional hooks for this.

Anyways, I will wait for the next release to see what is better.
