The options are:
- Figure out what the other device is and assign them both to the guest
- Tell Xen that you don't mind the sharing.
You should only do #2 if you're not using Xen for isolation -- i.e., if you trust the software in that VM not to attack dom0.
I *think* you should be able to do #2 by adding 'rdm_policy=relaxed' to your pci stanza; i.e., it should look like this:
pci=['00:1a.0,rdm_policy=relaxed']
Dear George That worked, do I still need to add this to the cfg file?
usb=1 usbdevice=['host:0529:0514']
or how do I assign the device without the 'rdm_policy=relaxed' option as per option 1?
Thanks so much for your speedy advice. Francis
