What do you mean by "connecting at the same time"? The semantics of a block service is that a volume is mounted by a single user at a time.
When you want something more complex you should build that with a proxy on top of the base service. What you are talking about is a very
Specialized need with your own logic on how to reconcile conflicting writes from your two mounts.

As far as I know, the current volume service doesn't support connecting the same volume to multiple instances at the same time, so neither of these can work directly through nova apis.
