Nested VMX: Clear bit 31 of IA32_VMX_BASIC MSR
|
|
|
|
The bit 31 of revision_id will set to 1 if vmcs shadowing enabled. And
|
|
according intel SDM, the bit 31 of IA32_VMX_BASIC MSR is always 0. So we
|
|
cannot set low 32 bit of IA32_VMX_BASIC to revision_id directly. Must clear
|
|
the bit 31 to 0.
