Centuar and Zhaoxin CPUs also support VMX.
commit 8f63aaf5c493c6502a058585cdfa3c71cdf8c44a Author: Sean Christopherson <seanjc@google.com> Date: Fri Dec 20 20:45:13 2019 -0800
KVM: VMX: Allow KVM_INTEL when building for Centaur and/or Zhaoxin CPUs
Change the dependency for KVM_INTEL, i.e. KVM w/ VMX, from Intel CPUs to any CPU that supports the IA32_FEAT_CTL MSR and thus VMX functionality. This effectively allows building KVM_INTEL for Centaur and Zhaoxin CPUs.
