PCI Express to PCI bridge
Summary: Code an emulated PCIe to PCI bridge for QEMU PCI Express machines
Modern Virtual Machines and their devices are PCI Express, however a means of supporting existing PCI and PCI-X deployment is required. Some use cases may need a means of using legacy PCI devices that plug into platforms that exclusively support PCI and PCI-X system slots.
QEMU already has such a device, i82801b11 DMI-to-PCI Bridge Emulation. However, the device has some short-comes
