    How does virtio conflict with this goal? Barring bugs in virtio (because there can be bugs in any driver, virtio drivers are even less likely to have bugs due to virtio being drastically simpler than any emulated hardware)?

    Assuming there really are people who encrypt everything, including memory, and use hardware features like secure enclaves to store encryption keys... If you don't trust your host and want to have nothing to do with it, then you really have no point in using virtio-fs in the first place, don't you?

    That's virtio. It's explicitly designed this way.

    Also, what's wrong with sharing memory between the host and the client?

    Sure it's faster. Since it's directly sharing memory between the host and the client. So much for isolation...
