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. ✅

    • 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. ✅
