Module FeatureCompatLate Power on Failed

Asked By 0 points N/A Posted on -

I can't seem to make the masking tests work to be able to check on the CPU checking code so not to use the whole test equipment when needed. I tried masking vendor but when I tried to run on the Workstation 9 and Fushion 5, an error always appear and I'm not sure how to fix it. The error is enclosed below. I tried masking from Intel to AMD.

Cpuid – VMware Workstation

Feature 'cpuid.AMD' was absent, but must be present.

Module FeatureCompatLate power on failed.

Failed to start the virtual machine.

Module FeatureCompatLate Power on Failed


When you receive an error similar to “Module FeatureCompatLate power on failed”, this normally happens when the host was removed while it was previously in an EVC cluster. The common symptoms that you may experience include: unable to power on a virtual machine, when powering a virtual machine on a standalone host it fails, and others.

This problem can be fixed by disabling the CPU masks from the host. To do this, logon to the vSphere Client using administrator privileges and then pick the host in the inventory. Go to Configuration tab then click Advanced Settings under Software. Expand Config, Defaults then click “cpuidMask”. Set all values to “disable” all the way through “Config.Defaults.cpuidMask.mode.8000000A.edx”.

After that click OK and power on the virtual machine.
