Help text

Checks that KVM's page table management code will not incorrectly let guests receive a virtualization exception. Virtualization exceptions will be trapped by the hypervisor rather than injected in the guest.

Note: some CPUs appear to generate spurious EPT Violations #VEs that trigger KVM's WARN, in particular with eptad=0 and/or nested virtualization.

If unsure, say N.
