Hi,
I've tried to use hook hostusb, I've installed vdsm-hook-hostusb.noarch 0:4.16.10-0.el6, and 
followed the documentation on http://www.ovirt.org/Vdsm_Hooks, but the new hook doesn't appear on 
the UI using "Edit VM" and "custom properties".
Is there any other way to install hooks, the documentation is not so clear, and 
I'm not very fine with python.
Thanks


you don't need to know python.

did you run the engine side commands (engine-config -sUserDefinedVMProperties... and restarted the engine)?

Hi,
Thank you for your answer, I've tried to insert my USB modem, but it doesn't up 
in the Windows VM.
I've tried to insert via virt-manager without success, I can't apply the 
modification, however I see the modem using lsusb :

lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device

Corp. Virtual Keyboard/Mouse Bus 002 Device 010: ID 0572:1321 Conexant Systems 
(Rockwell), Inc.

I've unload the "cdc_acm" kernel module via rmmod without success.
I've also tried to edit the xml appending the ID and VENDDOR tags :

    <hostdev mode='subsystem' type='usb'>
         <source>
           <vendor id='0x0572'/>
           <product id='0x1321'/>
         </source>
       </hostdev>

Ut at the first load the config disappears...
Do I need to restart the host or restart libvirtd services ?

Thanks for your help
Alain

Subject: [ovirt-users]  USB Modem in a VM

Hi,

Can you tell me if I can use an USB modem through one of the
hypervisor hosts to a Windows VM ?

I’d like to install a Windows Fax Server.

Thank you for your answers.



should be possible using qemu args: -usbdevice
host:vendor_id:product_id

in libvirt replace @VENDOR@ and @DEVICE@ to device specific properties:

<domain type='kvm'>
     <name>...</name>
     …
     <devices>
       …
       <hostdev mode='subsystem' type='usb'>
         <source>
           <vendor id='0x@VENDOR@'/>
           <product id='0x@DEVICE@'/>
         </source>
       </hostdev>
     </devices>
</domain>

if this option is not exposed in ui you can use vdsm-hooks[1] to modify the 
libvirt configuration and inject such device.

Regards,
Alon
