I'm using Spice and want to share a USB device on workstation with a
VM running on another physical host. The filters are all set up for
the VM in its domain XML. The Spice "Select USB devices for
redirection" dialog shows 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, 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!
