+#### Control Registers
+
+* The CR0 field must not set any bit to a value not supported in VMX operation (see Section 23.8). The following
+are exceptions:
+
+    - Bit 0 (corresponding to CR0.PE) and bit 31 (PG) are not checked if the “unrestricted guest” VM-execution
+control is 1.
+
+    - Bit 29 (corresponding to CR0.NW) and bit 30 (CD) are never checked because the values of these bits are
+not changed by VM entry; see Section 26.3.2.1.
