On newer libvirt/qemu it seems PCI hot-plugging could be an issue as seen in: https://www.suse.com/support/kb/doc/?id=000019383 https://bugs.launchpad.net/nova/+bug/1836065 This was found to be true on ARM64/aarch64 platform (tested on RaspberryPi4). As per the default machine doc, it advises to pre-allocate PCI controllers on the machine and pcie-to-pci-bridge based controller for legacy PCI models: https://libvirt.org/pci-hotplug.html#x86_64-q35 This patch introduces the concept as a workaround until a proper fix is done (ideally in the upstream libvirt/qemu projects). Until then client code can add 32 PCI controllers and a pcie-to-pci-bridge controller for aarch64 platforms. Signed-off-by: Rohit Yadav <rohit.yadav@shapeblue.com> |
