vmcs12 represents the per-CPU cache of L1 active vmcs12. This cache can be loaded by one of the following: 1) Guest making a vmcs12 active by exeucting VMPTRLD 2) Guest specifying eVMCS in VP assist page and executing VMLAUNCH/VMRESUME. Either way, vmcs12 should have revision_id of VMCS12_REVISION. Which is not equal to eVMCS revision_id which specifies used VersionNumber of eVMCS struct (e.g. KVM_EVMCS_VERSION). Specifically, this causes an issue in restoring a nested VM state because vmx_set_nested_state() verifies that vmcs12->revision_id is equal to VMCS12_REVISION which was not true in case vmcs12 was populated from an eVMCS by vmx_get_nested_state() which calls copy_enlightened_to_vmcs12().
