* Customer Concern:
* The concern is that VMs may be forced to repeatedly migrate between nodes during a Nutanix cluster upgrade.
* Nutanix Feature:
* CVM Autopathing: This feature ensures continuous VM operation by dynamically rerouting I/O and network traffic during node maintenance or upgrades.
* Explanation:
* CVM Autopathingallows VMs to remain on their current hosts while the Controller VM (CVM) handles the necessary I/O redirection.
* This minimizes the need for VM migrations, thereby reducing the operational impact during upgrades.
* Outcome:
* VMs can remain on their original hosts throughout the AOS upgrade process, ensuring minimal disruption and maintaining performance stability.
