For non pci express passthrough additional addresses are reserved. For pcie passthrough pcie root ports are needed (unless guest is like windows 7). The first 4 pcie root ports are defined by default in the pve-q35*.cfg files. If more than 4 pcie devices are passed through the needed root ports are created on demand. This helps to keep live migration possible without adding a new pve-q35*.cfg file. For the windows 7 like guests additional addresses are reserved as well.
