I just stumbled upon the function snd_intel8x0_inside_vm(), and quite
frankly the code seems bizarre:

        /* detect KVM and Parallels virtual environments */
        result = kvm_para_available();
        result = result || boot_cpu_has(X86_FEATURE_HYPERVISOR);
        if (!result)
                goto fini;

Why don't we simply rely on the PCI SSIDs?
