Libvirt native C API and daemons
01b8812765
We had been setting the device alias in the devinceinfo for pci controllers to "pci%u", but then hardcoding "pci.%u" when creating the device address for other devices using that pci bus. This all worked just fine until we encountered the built-in "pcie.0" bus (the PCIe root complex) in Q35 machines. In order to create the correct commandline for this one case, this patch: 1) sets the alias for PCI controllers correctly, to "pci.%u" (or "pcie.%u" for the pcie-root controller) 2) eliminates the hardcoded "pci.%u" for pci controllers when generatuing device address strings, and instead uses the controller's alias. 3) plumbs a pointer to the virDomainDef all the way down to qemuBuildDeviceAddressStr. This was necessary in order to make the aliase of the controller *used by a device* available (previously qemuBuildDeviceAddressStr only had the deviceinfo of the device itself, *not* of the controller it was connecting to). This made for a larger than desired diff, but at least in the future we won't have to do it again, since all the information we could possibly ever need for future enhancements is in the virDomainDef. (right?) This should be done for *all* controllers, but for now we just do it in the case of PCI controllers, to reduce the likelyhood of regression. |

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.
