+          qemu: Detect host CPU model by asking QEMU on x86_64
+        </summary>
+        <description>
+          Previously, libvirt detected the host CPU model using CPUID
+          instruction, which cased libvirt to detect a lot of CPU features
+          that are not supported by QEMU/KVM. Asking QEMU makes sure we
+          don't start it with unsupported features.
