# VMCS - Guest Fields

|
#### 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.
|
|
|
|
|
|
|
|
|
|
|
|
* The following checks are performed on processors that support Intel 64 architecture:
|
|
|
|
|
|
|
|
|
|
|
|
- If the “IA-32e mode guest” VM-entry control is 1, bit 31 in the CR0 field (corresponding to CR0.PG) and
|
|
|
|
|
|
bit 5 in the CR4 field (corresponding to CR4.PAE) must each be 1. :white_check_mark:
|
|
|
|
|
|
|
|
|
|
|
|
- If the “IA-32e mode guest” VM-entry control is 0, bit 17 in the CR4 field (corresponding to CR4.PCIDE)
|
|
|
|
|
|
must be 0.
|
|
|
|
|
|
|
|
|
|
|
|
- The CR3 field must be such that bits 63:52 and bits in the range 51:32 beyond the processor’s physicaladdress
|
|
|
|
|
|
width are 0.
