[libvirt-users] Encrytped USB devices

Hi here! How libvirt virsh solves attachment of hot plug/unplug encrytped USB devices?? We've no problems attaching full encrypted(LUKS) usb disk or memory pen to guest using virsh attach-disk command. But not working using virsh attach-device to use USB pass-through and hot plug/unplug features. USB pass-through works properly without encryption. Any procedure to make it working?, attach-disk expects for a static source (for example /dev/sdX), and we need some dynamical source assigment due USB temporal and different host target, it's why we're trying the attachment via attach-device to take advantage of plug/unplug via USB pass-through, but only works on non-encrypted usb devices. We unknow if exist any alternatively way to make attach-disk more dinamically, maybe by udev script or uuid source identification and some re-attach procedure, any recommendation?? or virsh command direct solution?? Thanks P.D. Please be free to move at libvir-list(a)redhat.com (for development) if it's a new requested feature or fixing.
