Comprehensive and Detailed Explanation From Exact Extract of Nutanix End User Computing documents:

According to Nutanix AHV Best Practices for Virtual Desktop Infrastructure (VDI):

Power Management: The most critical "optimal" configuration for latency-sensitive EUC workloads is to ensure the host power management policy is set to High Performance. This prevents the CPU from entering power-saving states (C-states/P-states) which can introduce latency during user interaction.

Memory Configuration: While Nutanix AHV typically disables memory overcommit by default (or does not use it in the same way as other hypervisors for VDI), the active configuration step required by an administrator to guarantee optimal performance is the Power Management setting. Memory reservation should generally be 100% (not 50%) to avoid swapping, and CPU/Memory shares are usually left at default unless there is specific contention, but Power Management is the baseline requirement for EUC optimization.

Why not D? While memory overcommit should be disabled for VDI, in many AHV versions this is the default behavior or inherent architecture. "High performance power management" represents the specific tuning parameter that administrators must validate or configure (often in the BIOS or via AHV command) to ensure the environment is "optimized" for desktop workloads.
