Hello,
I run oVirt 4.2.1, in 4.1 I added a USB device to a VM and now I wanted to
change this device to a different VM.
But I found out, that I'm not able to remove this device nor I'm able to
add any device to any VM. The device list is empty.
I found a bug report, what describe this error:
https://bugzilla.redhat.com/show_bug.cgi?id=1531847
Is there a solution for that?
The USB device is a hardware dongle and it is very impotent for us to
change this.
Any workaround is welcome!
Regards
Jonathan

A little update:
I found out that I have to activate *Hostdev Passthrough* (is this really
necessary for USB devices?). Now I see all the devices and I can add also
an USB device.
But I'm still not able to disconnect the USB from the old VM.

Theoretically, no, it is not needed.
Practically, it is needed in previous versions of 4.2 due to a bug that
would be solved in the upcoming version of 4.2 [1].
But I'm still not able to disconnect the USB from the old VM.
Yep, that's another bug that would be solved in the upcoming version of 4.2
[2].

If you can't wait for the upcoming version of 4.2 you can try removing it
manually by manipulating the database (assuming there is only one host
device attached to the VM):
(1) delete from vm_device where vm_id in (select vm_guid from vm_static
where vm_name='<vm name>') and type='hostdev';
(2) update host_device set vm_id = NULL where vm_id in (select vm_guid from
vm_static where vm_name='<vm name>');
