Recently i have upgraded some Firmware for one of the cluster. Firmware upgrade has migrated all VMs to other host and put the host into maintenance mode. i was cross checking the behavior on vcenter and found in tune as per process but after migrating all VMs to other host it reset the uptime for all migrated VMs in vcenter logs/view. but when checked guest os uptime then it was older than vcenter info. (VMs were not rebooted).
i am unable to understand that, is it a bug or do i have an issue with Nutanix cluster.
