Fix Recommendation

1. Nutanix AOS, Prism Central, and Files OS VMs have the OpenSSH-Server package preinstalled as part of its base package set. If the package is not installed, some corruption has taken place and the CVM must be rebuilt.

2. For Nutanix AHV, if the system's BIOS setup configuration permits toggling the No Execution bit, then set "/proc/cpuinfo" to "enable".
