A DisableDRSvMotion policy applied to a VM prevents DRS from migrating the VM to a different host unless the current host fails or is put into maintenance mode.
This type of policy can be useful for a VM running an application that creates resources on the local host and expects those resources to remain local. If DRS moves the VM to another host for load-balancing or to meet reservation requirements, resources created by the application are left behind and performance can be degraded when locality of reference is compromised.
A Disable DRS vMotion policy takes effect after a tagged VM is powered on, and is intended to keep the VM on its current host as long as the host remains available. The policy does not affect the choice of the host where a VM is powered on.
