Previous refactoring of the guest PCI address reservation/allocation code allowed for slot types other than basic PCI (e.g. PCI express, non-hotpluggable slots, etc) but would not auto-allocate a slot for a device that required any type other than a basic hot-pluggable PCI slot. This patch refactors the code to be aware of different slot types during auto-allocation of addresses as well - as long as there is an empty slot of the required type, it will be found and used. The piece that *wasn't* added is that we don't auto-create a new PCI bus when needed for anything except basic PCI devices. This is because there are multiple different types of controllers that can provide, for example, a PCI express slot (in addition to the pcie-root controller, these can also be found on a "root-port" or on a "downstream-switch-port"). Since we currently don't support any PCIe devices (except pending support for dmi-to-pci-bridge), we can defer any decision on what to do about this.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
