VM performance degraded after enabling Fault Tolerance (FT).

• Scenario / Problem Statement: Application inside VM slows down after FT enabled.

• Diagnosis:

  1. Check CPU reservations and FT logging network latency.

  2. Monitor network traffic on FT logging NIC.

  3. Verify compatibility of CPU for FT.

• Likely Cause: Insufficient bandwidth or CPU overhead due to FT.

• Resolution: Use a dedicated 10GbE NIC for FT logging, reserve CPU/memory, or upgrade host resources.
