Fixed In Version: vdsm-4.13.2-0.18.el6ev
Doc Type: Bug Fix
Doc Text:
Previously, balloon stats retrieval was gathered by a costly direct libvirt call in the getStats() body, resulting in a significant slowdown in this frequent API call. Now, the balloon information getter has been reimplemented as a sampling function, and moved into the VmStatsThread to make things more robust.
