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.

libvirt may automatically add a pci-root or pcie-root controller to a domain, depending on the arch/machinetype, and it hopefully always makes the right decision about which to add (since in all cases these controllers are an implicit part of the virtual machine). But it's always possible that someone will create a config that explicitly supplies the wrong type of PCI controller for the selected machinetype. In the past that would lead to an error later when libvirt was trying to assign addresses to other devices, for example: XML error: PCI bus is not compatible with the device at 0000:00:02.0. Device requires a PCI Express slot, which is not provided by bus 0000:00 (that's the error message that appears if you replace the pcie-root controller in a Q35 domain with a pci-root controller). This patch adds a check at the same place that the implicit controllers are added (to ensure that the same logic is used to check which type of pci root is correct). If a pci controller with index='0' is already present, we verify that it is of the model that we would have otherwise added automatically; if not, an error is logged: The PCI controller with index='0' must be " model='pcie-root' for this machine type, " but model='pci-root' was found instead.

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.
