There are a series of MSRs that tell you if a given CPU supports the '1' setting of unrestricted guest and a number of other virtualization features. The specific MSR is IA32_VMX_PROCBASED_CTLS2 and I believe unrestricted guest is bit 7 in the secondary proc controls VMC...
19、al processor is in VMX non-root operation. This fact may allow a VMM to prevent guest software from determining that it is running in a virtual machine.Because VMX operation places restrictions even on software running with current privilege level (CPL) 0, guest software can run at the ...

Since Workstation 14, another requirement is that it has to have VMX unrestricted guest support. See also: https://planetvm.net/blog/?p=3253 Unfortunately Intel does not list that capability at their website, which is why VMware added that specific test to their installer. You can add a...
Later processors support a VM-execution control called "unrestricted guest" (see Section 24.6.2). If this control is 1, CR0.PE and CR0.PG may be 0 in VMX non-root operation (even if the capability MSR IA32_VMX_CR0_FIXED0 reports otherwise).1 Such processors all...
