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.

Set pciConnectFlags in each device's DeviceInfo and then use those flags later when validating existing addresses in qemuDomainCollectPCIAddress() and when assigning new addresses with qemuDomainPCIAddressReserveNextAddr() (rather than scattering the logic about which devices need which type of slot all over the place). Note that the exact flags set by qemuDomainDeviceCalculatePCIConnectFlags() are different from the flags previously set manually in qemuDomainCollectPCIAddress(), but this doesn't matter because all validation of addresses in that case ignores the setting of the HOTPLUGGABLE flag, and treats PCIE_DEVICE and PCI_DEVICE the same (this lax checking was done on purpose, because there are some things that we want to allow the user to specify manually, e.g. assigning a PCIe device to a PCI slot, that we *don't* ever want libvirt to do automatically. The flag settings that we *really* want to match are 1) the old flag settings in qemuDomainAssignDevicePCISlots() (which is HOTPLUGGABLE | PCI_DEVICE for everything except PCI controllers) and 2) the new flag settings done by qemuDomainDeviceCalculatePCIConnectFlags() (which are currently exactly that - HOTPLUGGABLE | PCI_DEVICE for everything except PCI controllers). |

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.
