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

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

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
