        I use my own usbfilter.txt to replace the 
/etc/ovirt-engine/usbfilter.txt in the rhevm host.
        Then the vm can detect my usb device in the host ~

the usbfilter is only relevant for spice based connections (which allowremoting usb devices) as far i remember, not to hostusb which mounts ausb device at host side, not via spice.

Please cc the mailing list and share if hook is installed on the host and 
custom properties defined properly, also, lsusb from before you start the VM. 
Thanks.

Hello
        I read all your letter about USB Modem. But I'm confused that "USB Modem" means 
"USB Storage" or something else? I try to redirect the usb device in the host to vm 
(win7), but in vm there isn't any usb device.

It's working, in fact after the update from oVirt 3.4 to 3.5 my Cluster 
compatibility version was still in 3.4, I've changed it to 3.5 and the hostusb 
appeared...
Now the modem is well detected in my Windows 2008 VM.
Thank you very much everybody for your help Alain

Yes I made this :
engine-config -s "UserDefinedVMProperties=hostusb=0x0572:0x1321"
and nothing appear on the Edit VM, only :
- sndbuf
- vhost
- sap_agent
- viodiskattach

Is there any possibility to verify ?
The first command I put engine-config -s 
"UserDefinedVMProperties=hostusb=true;another_property=regexp" following the 
doc, maybe this option is blocking the hook ?

Hi,
I've tried to use hook hostusb, I've installed vdsm-hook-hostusb.noarch 0:4.16.10-0.el6, and

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 -s 
UserDefinedVMProperties... and restarted the engine)?

check http://blog.conoracallahan.com/blog/2014/07/19/ovirt-usb-passthrough/

Hi,

I've tried to insert via virt-manager without success, I can't apply the

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
