pc q35 based chipset emulator to support pci express natively. Based on Anthony Liguori's suggestion, the machine name is 'q35-next', with an alias of 'q35'. At this point, there are no compatibility guarantees. When the chipset stabilizes more, we will begin to version the machine names. Major features which still need to be added: -Migration support (mostly around ahci) -ACPI hotplug support (pcie hotplug support is working) -Passthrough support Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Jason Baron <jbaron@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
