Hi I have faced below error as unsupported Hardware detected. For this issue it cleared shown as “your hardware not supported” for RHEL 6.x series. So you have to collect below information. Share to you vendor check the compatibility.
1.Verify Linux OS version
2.Check VMware compatibility and enable EVC https://www.vmware.com/resources/compatibility/search.php?deviceCategory=cpu
3.Check Physical Server or blade supported processor list
