Isn't the entire VM classed as 'unpriviledged code' by whatever
container it's running in (e.g. the host kernel in the case of UML, or
domain 0 in the case of Xen)?

At least, I'd say that's the case if the VM system is emulating a
complete virtual machine.. with UML, I'd say the virtualisation boundary
lies at the syscall level within the UML instance.
