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.
