[Xen-devel] [PATCH v3 1/8] x86/nestedhvm: init nv_vvmcxaddr in hvm_vcpu_initialise()

[Sergey Dyasli <sergey.dyasli@xxxxxxxxxx>]

This allows to safely use nestedhvm functions that rely on the values
inside struct nestedvcpu independently of the nested virtualisation
(HVM_PARAM_NESTEDHVM) status of a domain.
