Issue/Introduction
Symptoms:
The vCenter server reports an error message similar to:
The host's CPU hardware does not support the cluster's current Enhanced vMotion Compatibility mode. The host CPU lacks features required by that mode.

Host is of type: vendor intel family 0x6 model 0x9e
The target host does not support the virtual machine's current hardware requirements.
Adding a host with Coffee Lake/Kaby Lake/Skylake client CPU (refer "Affected CPUs table") to the cluster with Intel "Skylake" Generation EVC mode enabled.
Affected CPUs:
| CPU Codename | Family/Model/Stepping |
|---|---|
| Skylake U/Y | 0x406e3 (6/4e/3) |
| Skylake H/S | 0x506e3 (6/5e/3) |
| Kaby Lake U/Y | 0x806e9 (6/8e/9) |
| Kaby Lake H/S/X | 0x906e9 (6/9e/9) |
| Coffee Lake U | 0x806ea (6/8e/a) |
| Coffee Lake S | 0x906eb (6/9e/b) |
| Coffee Lake H/S | 0x906ea (6/9e/a) |

Host is of type: vendor intel family 0x6 model 0x9e
The target host does not support the virtual machine's current hardware requirements.
Cause
The Skylake EVC mode is based on the feature set of Skylake server CPUs (specifically Skylake-SP). Kaby Lake and Coffee Lake only exist as client parts, and are missing several features that are present in Skylake-SP.
Resolution
To work around this issue, use Intel "Broadwell" Generation EVC mode.
