No, as the author of TinyKVM, the overheads of entering and leaving KVM is not the same order of magnitude as SFI. TinyKVM requires 2-3 microseconds to enter and leave, which is the lowest I ever managed to get while it still being robust and dependable sandbox. For some, that might seem really low, but keep in mind that libriscv which is the backbone of RVScript has 3 nanoseconds overhead.
