At vm startup and attach attempt to set the balloon driver statistics collection period based on the value found in the domain xml file. This is not done at reconnect since it's possible that a collection period was set on the live guest and making the set period call would reset to whatever value is stored in the config file. Setting the stats collection period has a side effect of searching through the qom-list output for the virtio balloon driver and making sure that it has the right properties in order to allow setting of a collection period and eventually fetching of statistics. The walk through the qom-list is expensive and thus the balloonpath will be saved in the monitor private structure as well as a flag indicating that the initialization has already been attempted (in the event that a path is not found, no sense to keep checking). This processing model conforms to the qom object model model which requires setting object properties after device startup. That is, it's not possible to pass the period along via the startup code as it won't be recognized. |

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.
