Change in ovirt-engine[ovirt-engine-4.1]: core: make the unmanaged usb controller to be managed

Piotr Kliczewski has submitted this change and it was merged. Change subject: core: make the unmanaged usb controller to be managed ...................................................................... core: make the unmanaged usb controller to be managed The issue: - a VM is started on an older (pre 4.0) engine - in this engine, if the USB is configured as disabled, no USB device is sent to VDSM - libvirt reacts by creating a new unmanaged USB controller - this controller appears in engine as an unmanaged device - after updating the engine, update of all VMs is called to modify the devices according to the need of the new engine - this code adds a managed USB controller - in this stage, this VM has 2 USB controllers, one managed and one unmanaged - from this point, anytime the USB devices are about to be touched (e.g. creating a new template from this VM or from a snapshot of the VM) a sanity check checking that there is only 1 USB controller fails throwing an exception The fix is to detect that the unmanaged device is the one created by libvirt and adopt it as ours. Another issue: If there are two usb controller for the VM: * managed, unplugged * unmanaged, plugged and a snapshot is made and then previewed, the VM has two managed usb controllers. It is caused by the fact that OVF doesn't store 'managed' flag. To mitigate this, every time normal usb controllers are updated and there are more then one managed controller, all controllers are removed and the proper one is recreated.
