[virt-tools-list] virt-manager and USB host device passthrough

[Daniel Berteaud]

Hi everyone.
I'm having a little problem with virt-manager 0.8 (from
http://markmc.fedorapeople.org/virt-preview/f11/) and USB host device
passthrough.

If I use a local connection to libvirt, I can see USB devices, and
assign it to my guests without problem. But when I connect to a remote
libvirt (qemu+ssh://virt/system), I cannot. The dropdown list for USB
Device only contains "000:000 USB Raw Device Access" lines. (See the
attached screenshot)

Remote libvirt is 0.7.0 running on CentOS 5.3

Using virsh, I can see the devices I want to attach:

virsh -c qemu+ssh://virt/system nodedev-list --cap usb
Connecting to uri: qemu+ssh://virt/system

usb_device_46b_ff10_serial
usb_device_46b_ff10_serial_if0
usb_device_46b_ff10_serial_if1

(the device I want to attach is usb_device_13fe_1d23_07780BA646FD, it's
a kingston USB Key).

On the physical host, lsusb gives:

Bus 005 Device 001: ID 0000:0000  
Bus 005 Device 002: ID 046b:ff10 American Megatrends, Inc. 
Bus 004 Device 001: ID 0000:0000  
Bus 007 Device 001: ID 0000:0000  
Bus 006 Device 001: ID 0000:0000  
Bus 008 Device 001: ID 0000:0000  
Bus 002 Device 006: ID 13fe:1d23 Kingston Technology Company Inc. 
Bus 002 Device 001: ID 0000:0000  
Bus 001 Device 001: ID 0000:0000  
Bus 003 Device 001: ID 0000:0000  
Bus 003 Device 002: ID 413c:2003 Dell Computer Corp. Keyboard

If I manually create an XML file for this device, I can attach it to my
guest using virsh, but, it'd be much simpler with virt-manager ;)

PCI devices listing seems to work in virt-manager (I didn't try to pass
PCI devices, but at least I can see them in the drop down list of
virt-manger).

Is this a known problem (remote USB device listing not working) or is
this a bug ?

Regard, Daniel
