Historically, the way to set PC speaker for a guest was to pass: -soundhw pcspk but as of QEMU commit v5.1.0-rc0~28^2~3 this is deprecated and we should use: -machine pcspk-audiodev=$id instead. The old way was then removed in commit v7.1.0-rc0~99^2~3. Now, ideally we would have a capability selecting whether we talk to a QEMU that understands the new way or not. But it's not that simple - the machine attribute is just an alias to the .audiodev= attribute of 'isa-pcspk' object and both are created in pc_machine_initfn() function, i.e. not then the PC_MACHINE() class is initialized, but when it's instantiated. IOW, it's not possible for us to query whether we're dealing with older or newer QEMU. But given that the newer version is supported since v5.1.0 and the minimal version we require is v4.2.0 (i.e. there are two releases which don't understand the newer cmd line) and how frequently this feature is (un-)used (the issue was reported after ~1 year since it stopped working), I believe we can live without any capability and just use the newer cmd line unconditionally.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
