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.

Peter Krempa bc130288a3 qemu: command: Introduce JSON equivalent of qemuBuildDeviceAddressStr
Upcoming patches will start converting the formatting of arguments for
-device from a string to JSON so that we can keep proper types around
when using it via QMP.

This means we will need an equivalet for the device address builder
function. 'qemuBuildDeviceAddressProps' provides equal functionality,
but the output differs for fields where a number is expected, where
we've previously formatted a hex value but now end up with a decimal
value per JSON standard.

For given address types I've selected an example device and used
'-device $DEV,help' to obtain the current types recognized by qemu:

Note that 'bus' is not shown below, but it's already a string so we can
keep using it as a string.

VIR_DOMAIN_DEVICE_ADDRESS_TYPE_PCI (virtio-balloon-pci)
  acpi-index=<uint32>    -  (default: 0)
  addr=<int32>           - Slot and optional function number, example: 06.0 or 06 (default: -1)
  multifunction=<bool>   - on/off (default: false)

Note that 'addr' is here defined as 'int32' but in fact internally in
qemu is an alternate type between a number and a string so we can keep
using strings here.

VIR_DOMAIN_DEVICE_ADDRESS_TYPE_USB (usb-tablet)
  port=<str>

VIR_DOMAIN_DEVICE_ADDRESS_TYPE_SPAPRVIO (spapr-vty)
  reg=<uint32>           -  (default: 4294967295)

VIR_DOMAIN_DEVICE_ADDRESS_TYPE_CCW (virtio-blk-cww)
  devno=<str>            - Identifier of an I/O device in the channel subsystem, example: fe.1.23ab

VIR_DOMAIN_DEVICE_ADDRESS_TYPE_ISA (isa-serial)
  iobase=<uint32>        -  (default: 4294967295)
  irq=<uint32>           -  (default: 4294967295)

VIR_DOMAIN_DEVICE_ADDRESS_TYPE_DIMM (pc-dimm)
  slot=<int32>           -  (default: -1)
  addr=<uint64>          -  (default: 0)

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.
