Not really.  The guest and host admins are usually different people, who

LOL, let me be the malicious host admin, then you can be the guest,
there is no way you can protect yourself. If you don't trust the host,
don't use it.

All your IO flows through the host, all your sekrit keys are in memory,
there is no security.

That's true. But guest admins are going to be unhappy about a file server serving their data to the host all the same.
