While installing ESXi operating system on the server, I was receiving below warnings errors regarding CPU hardware Virtualization.
Check out: VMware ESXi 8.0 step by step Installation guide with Screenshots
Error(s)/Warning(s) Found During System Scan The system encountered the following warnings(s) Warning(s) <HARDWARE_VIRTUALIZATION WARNING: Hardware Virtualization is not a feature of the CPU, or is not enabled in the BIOS>
For this simple solution is enable Virtualization Technology or Secure Virtual Machine mode in the BIOS of physical server. When enabled a Virtualization Technology, VMM (Virtual Machine monitor) can utilize the additional hardware capabilities provided by Intel or AMD CPU technology. This technology allows a platform to run multiple operating system and applications in independent partitions.
If incase Virtualization technology is already enabled in the system BIOS and you are still getting warning error or you are trying to install nested hypervisor ESXi, (Install ESXi OS as Virtual Machine on ESXi Server), You may encounter HARDWARE_VIRTUALIZATION WARNING on ESXi Virtual Machine. To resolve this issue Log onto ESXi or vCenter server, right click and Edit Settings of Virtual Machine on where you are going to install ESXi operating system.
Under Virtual Hardware expand CPU option, Go to Hardware virtualization and click check box on Expose hardware assisted virtualization to the guest OS. Click OK.
Incase you are trying to install nested ESXi server on VMware Workstation Edit Virtual Machine Settings, Select Processors, In the Virtualization engine, click check box of Virtualize Intel VT-x/EPT or AMD-V/RVI. And you are done.
Once VM is started to install ESXi server OS, The warning error is gone.
