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) Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Ján Tomko <jtomko@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.
