I used the Web UI for this testing but made a quick test with pvesh on the API (/cluster/mapping/pci). PCI: * Passed through single PCI devices and groups (Pass through all functions as one device). works fine USB/PCI: * made a mapping for 2 nodes and started a vm using that mapping on each node. works fine provoke errors: * "PCI device map for 'mapping1' not found" is displayed when starting a VM if a map was added that has no configuration for this node. Also displays a warning when adding a map that has no configuration. * could only migrate if PCI/USB Mapping is preset on the target node * logically could not live migrate with PCI/USB Devices assigned. Error handling also works fine There is only one thing I noticed: * When assigning multiple devices to a node, not all of them are passed through, just one. There is a hint field (multiple_warning) which is not visible right now.
