[libvirt] [PATCH 1/1] vz: unlock dom until resize operation

[libvirt] [PATCH V2] libxl: add default controllers for USB devices
by Jim Fehlig 23 May '17

23 May '17

Attempting to start a domain with USB hostdevs but no USB controllers fails with the rather cryptic error libxl: error: libxl_qmp.c:287:qmp_handle_error_response: received an error message from QMP server: Bus 'xenusb-0.0' not found This can be fixed by creating default USB controllers. When no USB controllers are defined, create the number of 8 port controllers necessary to accommodate the number of defined USB devices. Note that USB controllers are already created as needed in the domainAttachDevice code path. E.g. a USB controller will be created, if necessary, when attaching a USB device with 'virsh attach-device dom usbdev.xml'.
