[fedora-virt] How To Get Fedora 10 Guest To See USB Device?

[Robert L Cochran]

Here is the xml I have for my Fedora 10 guest machine running in my
Fedora 10 host machine.

Question: if I plug a USB flash drive into the host, how do I make that
accessible (as in readable and writable) to the guest machine? Look at
the <hostdev... > ebtry I have coded below. I must be doing something
wrong because when I:

*plug the flash drive in to the host
*verify the drive is mounted on the host
*start the guest

the guest cannot see that flash drive. Is the xml formatted incorrectly?
Or do I have to do something in the guest? Or do I need to plug the
flash drive in after starting the guest?
