This controller provides a single PCIe port on a new root. It is similar to pci-expander-bus, intended to provide a bus that can be associated with a guest-identifiable NUMA node, but is for machinetypes with PCIe rather than PCI (e.g. q35-based machinetypes). Aside from PCIe vs. PCI, the other main difference is that a pci-expander-bus has a companion pci-bridge that is automatically attached along with it, but pcie-expander-bus has only a single port, and that port will only connect to a pcie-root-port, or to a pcie-switch-upstream-port. In order for the bus to be of any use in the guest, it must have either a pcie-root-port or a pcie-switch-upstream-port attached (and one or more pcie-switch-downstream-ports attached to the pcie-switch-upstream-port).
