Dtdx.rst200 implemented using a Virtualization Exception (#VE) that is handled by the
201 guest kernel. A #VE is handled entirely inside the guest kernel, but some
212 #VE or #GP exceptions.
217 Instruction-based #VE
245 - #VE generated
252 The #VE MSRs are typically able to be handled by the hypervisor. Guests
253 can make a hypercall to the hypervisor to handle the #VE.
276 A #VE is generated for CPUID leaves and sub-leaves that the TDX module does
280 #VE on Memory Accesses
