# Due to the nature of q35 model, there are no hotplugging slots available. See
# https://libvirt.org/pci-hotplug.html for more info. We need to hack the
# libvirt config (raw data) to have:
#
# pcie-root - normally autocreated but needs to be defined here
# pcie-to-pci-bridge - for legacy devices to hotplug to like virtio networking
# pcie-root-port - A large number of ports defined. The normal devices (disks
# etc) will take these first so we need a number of additional free ones.
