On x86-64/q35 and aarch64/virt instances libvirt adds as many pcie-root-port entries (aka virtual pcie slots) as it needs and adds one free. If we want to hotplug network interfaces or storage devices then we quickly run out of available pcie slots. This patch allows to configure amount of PCIe slots in instance. Method was discussed with upstream libvirt developers. To have requested amount of pcie-root-port entries we have to create whole PCIe structure starting with pcie-root/0 and then add as many pcie-root-port/0 entries as we want slots. Too low value may get bumped by libvirt to same as amount of inserted cards. Systems not using new option will work same way as they did.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
