Need to implement CPU masking according to KB 1993 to overcome Intel ecx error on vMotion.
I added
<guestOSDescriptor>
<esx-3-x-x>
<all-versions>
<all-guests>
<cpuFeatureMask>
<default-vendor>
<level-1>
<ecx>--:::-x:--:x-:---x:-x-x</ecx>
<edx>--:::x-:--:::--</edx>
</level-1>
</default-vendor>
<amd>
<level-1>
<ecx>--:::::::-x</ecx>
</level-1>
</amd>
</cpuFeatureMask>
</all-guests>
</all-versions>
</esx-3-x-x>
</guestOSDescriptor>
to my vpxd.cfg and restarted, but still get the error on vMotion attempt
