[libvirt] [PATCH] Don't use %.3d format for bus/addr of USB devices.

Tuesday, 26 October 2010

When using 0-prefixed numbers, QEmu will interpret them as octal numbers
(as C convention says); this means that if you attach a device that has
addr > 10 (decimal) you're going to attach a different device.
