I'm trying to attach a USB device which is attached to my host to a guest instance. The device definition in the XML looks like:

<hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x046d'/> <product id='0xc111'/> </source> </hostdev>

and the device appears in lsusb as USB device 002:018:

Bus 002 Device 018: ID 046d:c111 Logitech, Inc.

but when I try and start the guest libvirt appears to try and use a different device which doesn't exist:

error: unable to set security context '107:107' on '/dev/bus/usb/002/022': No such file or directory

This is using the current libvirt-0.7.6-1.fc12.x86_64 package from the F12 virt-preview repository.

This is a mixup of decimal/octal - I've just posted a patch for it http://www.redhat.com/archives/libvir-list/2010-February/msg00377.html Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
