N-Convex Algorithm
The guest runs in a separate virtual address space enforced by the CPU hardware. A bug in the guest kernel cannot access host memory because the hardware prevents it. The host kernel only sees the user-space process. The attack surface is the hypervisor and the Virtual Machine Monitor, both of which are orders of magnitude smaller than the full kernel surface that containers share.
