Re: [fedora-virt] Some USB devices are blocked by host policy

I'm using Spice and want to share a USB device on workstation

the device I want to redirect. However, all the USB devices are greyed out
and Alert text says, "Some USB devices are blocked by host policy". My
understanding, from the doc
<https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/...;,
is that the following XML needs to be configured on the "host physical
machine's domain XML" which I am interpreting as the workstation, although it
could be the hypervisor host, to unblock the USB device:
<redirfilter>
<usbdev class='0x08' vendor='0x0951' product='0x1625'
version='2.0' allow='yes'/>
<usbdev allow='no'/>
</redirfilter>
Either way, I cannot figure out what the name or location of the file where
this XML would go, let alone find a complete schema or example of what the
file would look like. Has anyone else done this? Please... <gasp> Help!
I've never seen that message before. Can you provide the guest XML you are
using? And maybe upload a screenshot somewhere of what you are seeing in
virt-viewer.
What type of device are you trying to passthrough?
