This fixes: https://bugzilla.redhat.com/show_bug.cgi?id=979290 https://bugzilla.redhat.com/show_bug.cgi?id=979330 The node device driver was written with the assumption that udev would use a "change" event to notify libvirt of any change to device status (including the name of the driver it was bound to). It turns out this is not the case (see Comment 4 of BZ 979290). That means that a dumpxml for a device would always show whatever driver happened to be bound at the time libvirt was started (when the node device cache was built). There was already code in the driver (for the benefit of the HAL backend) that updated the driver name from sysfs each time a device's info was retrieved from the cache. This patch just enables that manual update for the udev backend as well.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
