Description of problem: Since usb-ccid controllers are formatted before usb-hubs on the QEMU command line, so guest will fail to start if plug a ccid controller on hub. Version-Release number of selected component (if applicable): libvirt-2.0.0-8.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. define and edit a guest like following : #virsh dumpxml vm2 ...... <controller type='ccid' index='0'> <address type='usb' bus='0' port='6.1'/> </controller> <smartcard mode='passthrough' type='spicevmc'> <address type='ccid' controller='0' slot='0'/> </smartcard> ...... 2. start guest # virsh start vm2 error: Failed to start domain vm2 error: internal error: qemu unexpectedly closed the monitor: 2016-09-12T09:47:46.638568Z qemu-kvm: -device usb-ccid,id=ccid0,bus=usb.0,port=6.1: usb port 6.1 (bus usb.0) not found (in use?) Actual results: As step 2, guest with usb-ccid on hub fail to start. Expected results: Guest can start successfully or give some error like we cannot use it in this way. Additional info:
