Whenever the VMOTION happens the Application Users will loose connectivity at that time. But This does not happen always, but at times it does. We have raised several cases with Microsoft & VMware on this issue & have worked for several weeks, but they could not determine the actual cause. Besides, we also could not recreate the issue by doing vmotion manually.So the only way for Microsoft to investigate further is during a live issue. But in most cases it is not possible because we always had to fix the issue quickly during such instances than spending hours on troubleshooting.If anyone faced similar kind of issue in your environment kindly share me if you have an solution.
