It's actually

app -> vm kernel -> vm X server -> shared memory

					     shared memory -> xapp ->
kernel -> host X server ->gpu

The first chain runs independantly of the second. The frame rates I
mentioned are only refering to the second chain. Of there are multiple
instances of the first chain running, each at a different security

Nope, that would violate security requirements for separation.
