This change adds qemu backend command line support for enabling or disabling hotplug on the pci-root controller using the 'target' sub-element of the pci-root controller as shown below: <controller type='pci' model='pci-root'> <target hotplug='off'/> </controller> '<target hotplug='off/on'/>' is only valid for pc (i440fx-based x86) machinetypes and turns on the following command line option that is passed to qemu for x86 guests: -global PIIX4_PM.acpi-root-pci-hotplug=<off/on> Before introduction of this attribute, hotplug was always enabled for pci-root of an i440fx-based machinetype, and since its introduction the default setting has always been "on" for those machinetypes. This change also adds the required qemuxml2argv unit tests in order to test correct qemu arguments. Unit tests have also been added to test qemu capability validation checks.

==============================
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.
