The machine types historically have a default USB controller populated via '-usb' which libvirt assumed implicitly. Qemu will use 'pci-ohci' for both if '-usb' is used. Unfortunately an USB controller instantiated via '-usb' is unusable as the bus name libvirt generates doesn't reflect the real name qemu uses, and thus no libvirt-defined USB devices can be put on the controller. This patch will populate the default USB controller into the XML and select it's model to 'pci-ohci' unconditionally as the machine would fail to start with '-usb' if that controller model is not available. This patch doesn't try to make any other assumptions about auto-populated model of USB controllers, which means that for an explicit USB controller without model a different model will be picked. Note that this will likely cause ABI differences and break migration for the two machine types, in the corner case when the default USB controller would be populated, but given that both are obsolete board types and USB was unusable it doesn't make sense to keep supporting this specific case when '-usb' was formatted.

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.
