2024-06-08target/i386: enumerate VMX nested-exception supportXin Li1-0/+1
Allow VMX nested-exception support to be exposed in KVM guests, thus nested KVM guests can enumerate it. Tested-by: Shan Kang <shan.kang@intel.com> Signed-off-by: Xin Li <xin3.li@intel.com> Message-ID: <20231109072012.8078-6-xin3.li@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
