Hi there. I have a problem with USB host device enumeration with libvirt. I'm running libvirt 0.7.0 on a fully updated CentOS 5.3 (libvirt was rebuilt unmodified from http://libvirt.org/sources/libvirt-0.7.0-1.fc11.src.rpm) I want to pas an USB key to one of my guest. lsusb see it just fine: (I want to pass the device 13fe:1d23) 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 create a XML file for this device, I can attach it to my guest with virsh attach-device, no problem here. The problem is that libvirt cannot access the devices informations like pretty name, vendorID and productID, so for example, virt-manager only see devices with name "USB Raw Device Access" with 0000 as vendorID and productID. For example, for this particular USB key: virsh nodedev-dumpxml usb_device_13fe_1d23_07780BA646FD_0_usbraw <device> <name>usb_device_13fe_1d23_07780BA646FD_0_usbraw</name> <parent>usb_device_13fe_1d23_07780BA646FD_0</parent> <capability type='usb_device'> <bus>0</bus> <device>0</device> <product id='0x0000'>USB Raw Device Access</product> <vendor id='0x0000' /> </capability> </device> SELinux is in permissive mode. Anybody have an idea ? Where does libvirt get the info about host device ? (/sys ?) Regards, Daniel -- Daniel Berteaud FIREWALL-SERVICES SARL.
