VirtualBox is a powerful virtualisation product for enterprise as well as home use. VirtualBox isn’t only rich in functionalities, but also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL) version 3. In this artilce, we will show you how to install ESXi on a VirtualBox. Please see how to install Oracle VirtualBox on a Mac device, Demystifying Zero Trust with Veeam: Design your Architecture, how to Set Microsoft Defender Antivirus to Passive Mode or Active Mode.
VMware ESXi formerly known as ESX is a bare metal hypervisor that installs easily on to your server. VirtualBox runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems, and can be used to run ESXi.
Note: VirtualBox is not a supported environment! Because, I ordered some hardwares, I wanted to test to see the behaviour on Virtualbox. I proceeded with these steps. If you do not want to experience pains, please download ESXi 6.5.This article is only useful for Lab purposes or PoC. ESXi 8 raised the requirements when it comes to CPU compatibility. You will have a lot of errors in this regard. You will have to manually set the allowLegacyCPU=True in the boot.cfg. I hope this helps.
