[PATCH v3 0/4] nested vmx: enable VMCS shadowing feature

can dom0 modify Shadow PT of HVM domU?
Hi all,
Can Xen hypervisor modify HVM domU's Shadow page table, under the dom0's context, like trapped from dom0's hypercall?
I think it have to call 2 functions at least: guest_walk_tables() and flush_tlb_all(). Can these 2 functions called in dom0's context?
