When vmcs12 uses VPID, all TLB entries populated by L2 are tagged with vmx->nested.vpid02. Currently, INVVPID executed by L1 is emulated by L0 by using INVVPID single/global-context to flush all TLB entries tagged with vmx->nested.vpid02 regardless of INVVPID type executed by L1. However, we can easily optimize the case of L1 INVVPID on an individual-address. Just INVVPID given individual-address tagged with vmx->nested.vpid02.
