It is worth mentioning here that setting any of the flag bits in
kvm->arch.secure_guest will cause the assembly code that enters the
guest to call the UV_RETURN ucall instead of trying to enter the guest
directly.  That's not necessarily obvious to the reader as this patch
doesn't touch that assembly code.

Apart from that this patch looks fine.
