Enabling hardware virtualization in vSphere involves a few steps:
1. Verify that your processor and BIOS support virtualization technology.
1. Log in to the vSphere Web Client as an administrator and select the ESXi host.
1. Click on the Configure tab and select Hardware.
1. In the Hardware menu, click on the Processor card.
1. Under Processor, select Virtualization Technology.
1. Set Virtualization Technology to Enabled.
1. Click on Save and wait for the changes to take effect.
The technical process of enabling hardware virtualization involves modifying the settings of the ESXi host’s processor. This requires access to the host’s BIOS, which is the firmware that controls the basic input/output operations of the computer. By enabling the Virtualization Technology setting in the processor BIOS, you allow the virtual machine (VM) to access hardware resources more efficiently by allowing the hypervisor to use hardware-assisted virtualization. This enables better CPU and memory management, higher VM density, and better VM performance. Enabling hardware virtualization is essential for running multiple VMs on a single host in a vSphere environment.
