with qemu 4.0 we can make use of the new pcie-root-ports with settings for the width/speed which can resolve issues with some hardware combinations when negioating link speed so we add a new q35 cfg that we include with machine types >= 4.0 to preserve live migration of machines without passthrough but q35 for details about the link speeds see: pcie: Enhanced link speed and width support https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg02827.html Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
