This happens when a USB device is previously set to passthrough for one VM and then when the VM stops is disconnected. This error will not allow any physical soundcard or graphics card to passthrough to VM, and VNC will be the only working option.
This error is caused as even the unplugged usb disappears from the form view, the line that passes through said USB device is not removed in the XML file of the VM, causing this error.
