Re: [Xen-devel] [PATCH 1/4] x86/vvmx: Unconditionally initialise vmxon_region_pa during vcpu construction

> Update nvmx_handle_vmx_insn() to include the in-vmx mode check (for all
> instructions other than VMXON) to complete the set of #UD checks.
> In addition, sanity check that the nested vmexit handler has worked
