VMware vSphere 6.5 introduces Broadwell EVC Mode

To simplify vMotion across CPU generations VMware has introduced Enhanced vMotion Compatibility (EVC). EVC automatically configures server CPUs with Intel FlexMigration or AMD-V Extended Migration technologies to be compatible with older servers. In vSphere 6.5 a now EVC mode has been introduced.

Intel Broadwell Generation
Compared to Intel "Haswell" EVC mode, the 5th Gen Broadwell EVC mode exposes additional CPU features:

  • Transactional Synchronization Extensions
  • Supervisor Mode Access Prevention
  • Multi-Precision Add-Carry Instruction Extensions
