Created attachment 363350 [details] Screeshot of the dropdown list of USB Devices Description of problem: 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_0_0_0000_00_1a_0 usb_device_0_0_0000_00_1a_0_if0 usb_device_0_0_0000_00_1a_1 usb_device_0_0_0000_00_1a_1_if0 usb_device_0_0_0000_00_1a_2 usb_device_0_0_0000_00_1a_2_if0 usb_device_0_0_0000_00_1a_7 usb_device_0_0_0000_00_1a_7_if0 usb_device_0_0_0000_00_1d_0 usb_device_0_0_0000_00_1d_0_if0 usb_device_0_0_0000_00_1d_1 usb_device_0_0_0000_00_1d_1_if0 usb_device_0_0_0000_00_1d_2 usb_device_0_0_0000_00_1d_2_if0 usb_device_0_0_0000_00_1d_7 usb_device_0_0_0000_00_1d_7_if0 usb_device_13fe_1d23_07780BA646FD usb_device_13fe_1d23_07780BA646FD_if0 usb_device_413c_2003_noserial usb_device_413c_2003_noserial_if0 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).

Keyboard Version-Release number of selected component (if applicable): virt-manager 0.8.0 libvirt 0.7.0 (on CentOS) qemu-kvm 0.10.6 (from lfarkas repo, on CentOS) How reproducible: Always Steps to Reproduce: 1. Add hardware to a guest 2. Select Physical Host Device 3. Select USB Actual results: USB Devices not listed Expected results: USB Devices listed Additional info: 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).

Created attachment 363352 [details] virt-maanger.log Looks like there's nothing interesting here, but I attach it as asked on the mailing-list
Okay, I think this is pretty clearly a bug on the remote side: <device> <name>usb_device_46b_ff10_serial_usbraw</name> <parent>usb_device_46b_ff10_serial</parent> <capability type='usb_device'> <bus>0</bus> <device>0</device> <product id='0x0000'>USB Raw Device Access</product> <vendor id='0x0000' /> </capability> </device> Perhaps selinux is enabled and the CentOS 5.3 policy doesn't allow libvirt read from sysfs? Whatever the issue is, I'm pretty certain it's not a Fedora 12 issue, so I'm closing as NOTABUG. If the problem persists, it might be worth asking on libvir-list for help
Thanks. Selinux is in permissive mode on this host. So it looks like a bug on libvirt's side (or CentOS ?). I'll ask advices on libvirt-list Regards
