DSM is not a part of TVM. So it really depends on what kind of work did the admin virtqueue do. For commands that can't be self-contained like provisioning, it is fine, since it is done before the TDI assignment. But it not necessarily for your migration proposal. It seems you've found another case that self-containing is important: allowing the owner to access the member after TDI is attached to TVM is a side channel attack.
