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].

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='') and type='hostdev';
(2) update host_device set vm_id = NULL where vm_id in (select vm_guid from
vm_static where vm_name='');

[ovirt-users] Fwd: Can't add/remove usb device to VM

2018-02-12 Thread Jon bae
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.

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
