Probing for the NCR53C90 controller is a little unusual. The qom-list-types QMP command returns a list of all types known to the QEMU binary. It does not distinguish devices which are user creatable from those which are built-in. Any QEMU target that supports PCI will have the DC390 / AM53C974 devices because they are PCI based. Due to code dependencies in QEMU though, existence of these two devices will also pull in the NCR53C90 device (called just 'esp' in QEMU). The NCR53C90 is not user-creatable and can only be used when built-in to the machine type. This is only the case on sparc machines, and certain mips64 and m68k machines. IOW, we don't rely on qom-list-types as a guide for existence of NCR53C90, as it shouldn't really exist in most QEMU binaries. Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
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.
