OK, I can confirm that my VM configs start OK using xl. Unfortunately, xl in 4.2 doesn't support usb-add, so I cannot pass the required USB devices through, over and above the one I can pass in the config file. Will usb-add also be available in 4.3, in addition to the multi-device syntax in the config file? Any chance of the multi-device syntax also being patched into xm for 4.3? Gordan
