Cross site vMotion is a feature that really shows the power of the VMware platform. When combined with NSX you can move live running virtual machines across long distances. It’s a huge advantage for customers looking to balance workloads or avoid potential disasters. I learned today that this feature does require VMware’s virtual standard switch or distributed switch it will not work on any third party switches today. In addition there are only certain supported migration paths:
VSS = Virtual Standard Switch
VDS = Virtual distributed switch
There are only certain supported migration paths:
VSS -> VSS
VSS -> VDS
Notice that VDS -> VSS is not supported.
