For ESXi, NSX-T does not support the Host Profiles and Auto Deploy features.

Caution:

On RHEL, the yum update command might update the kernel version and break the compatibility with NSX-T. Be sure to disable the automatic kernel update when you run yum update. Also, after running yum install, verify that NSX-T supports the kernel version.
