KVM uses Intel's virtualization extensions (VT-x) for CPUID exits, and not the masking/faulting MSRs. CPUID support is controlled by userspace (i.e. outside KVM), using the KVM_GET_SUPPORTED_CPUID and KVM_SET_CPUID2 ioctl. The ioctls are documented in Documentation/virtual/kvm/api.txt. The KVM_SET_CPUID2 ioctl is not documented but it is the same as KVM_SET_CPUID, except that is uses "struct kvm_cpuid2" instead of "struct kvm_cpuid".
