Sean Christopherson [off-list ref] writes:

Initialize vm->memslots[] with an invalid memslots value during very
initial VM creation so that failure to configure the core memory regions
generates an immediate assert instead of potential weirdness, e.g. if slot0
is coincidentally valid.  This will also allow hardening the region APIs to
guard overriding a region's memslot multiple times.

Sure. Looks good overall. Please feel free to add:
