  • 1.  Enabling EVC on a VCF 5.2 Management Workload Domain Cluster

    Posted 25 days ago
    Dear all, good morning. I'm contacting you to ask if anyone has enabled EVC on a vSAN cluster in VCF with vCenter within the cluster.
    I hope you can help me. I'm getting the following error when trying to enable EVC: The host cannot be admitted to the cluster's current Enhanced vMotion Compatibility mode. Powered-on or suspended virtual machines on the host may be using CPU features hidden by that mode.
     
    I look forward to your comments.
    Thank you very much.
    Best regards.

    @Guillermo Argañaras,
    Hey, this error typically means that powered-on or suspended VMs are using CPU features that would be masked by the EVC mode you're trying to enable. And yes-this includes the vCenter VM itself, which complicates things since it's managing the cluster you're trying to modify.

    Well, VMware does not recommend enabling EVC post-deployment in VCF-managed vSAN clusters.

    Thank you!

    Although VCF 5.2 itself does not provide direct settings for EVC via the SDDC Manager, it is important to note that:

    • EVC is not managed by VCF, but by vSphere at the cluster level.
    • When setting up workload domains in VCF 5.2, you can configure EVC via the vSphere UI or API, provided you plan this in advance.
    • The official VCF 5.2 release notes and upgrade documentation do not explicitly mention EVC, which confirms that it falls outside the direct scope of VCF.

    At cluster creation evc can be set.

    https://developer.broadcom.com/xapis/vmware-cloud-foundation-api/5.2.1/data-structures/ClusterCreationSpec/
    "evcMode": "One among: INTEL_MEROM, INTEL_PENRYN, INTEL_NEALEM, INTEL_WESTMERE, INTEL_SANDYBRIDGE, INTEL_IVYBRIDGE, INTEL_HASWELL, INTEL_BROADWELL, INTEL_SKYLAKE, INTEL_CASCADELAKE, INTEL_ICELAKE, INTEL_SAPPHIRERAPIDS, AMD_REV_E, AMD_REV_F, AMD_GREYHOUND_NO3DNOW, AMD_GREYHOUND, AMD_BULLDOZER, AMD_PILEDRIVER, AMD_STREAMROLLER, AMD_ZEN, AMD_ZEN2, AMD_ZEN3, AMD_ZEN4",


    But update cluster does not have evc.
