Hello, What is the best option for USB support in ovirt Windows guests now? I see there are quite a lot of recent patches in this area. Regards, Nerijus

That depends mostly on which OS you're running on the client, if you're running Linux clients I would use the new opensource USB redirection support in Spice. This is not yet supported in ovirt, but if you use Fedora-16/17 or RHEL-6.3 beta on the hosts, then you can just inject the necessary xml bits into the libvirt xml file vdsm generates using a vdsm hook, the necessary bits are given here: http://hansdegoede.livejournal.com/11084.html This requires using Spice as display protocol and remote-viewer as the client, and is currently only supported with Linux clients, we're working on also adding support for USB-redirection to the windows builds of spice-gtk & remote-viewer. You may want to first play a bit with this using Fedora-16 host + client to see how all the bits fit together, a quick start for Fedora-16 is here: http://hansdegoede.livejournal.com/11084.html Regards, Hans

It seems to work with F16 host (spicy -h localhost -p 5902 shows relevant menus), thanks! But I could not test with a real USB device, because there are no USB devices plugged in a remote server. Is it possible to connect to a remote host, not localhost, with spicy? 5902 port is only opened on 127.0.0.1 by qemu-kvm. Regards, Nerijus

Sure, Just tell qemu/libvirt where spice server should be binded, for example: Add element <listen type='address' address='0.0.0.0'/> as child element of <graphics> element and spice server will listen on all interfaces (or choose only exact IP address where you want it to be binded). or Add option addr=0.0.0.0 into spice qemu command line options directly provided you run qemu-kvm manually. (Hope I understood the question).

Yes, it helped, thanks! Is it possible to achieve something like that with ovirt? I tried using spicy instead of spicec with spice-xpi plugin, but it didn't work. Regards, Nerijus

ovirt support for usb redirection is brewing. You could probably write a vdsm custom hook for usb & redir dev creation in the meanwhile. David

or test the patches in ovirt for doing that which are in review already for engine support of enabling this flag, then the user portal support will be added (should be a matter of weeks)
