You need to make sure your CPU is capable of VT-x (virtualization acceleration), and then that your BIOS has VT-x enabled. I am assuming you are running Ubuntu and have already installed and smoke tested KVM as described in my previous article. ![]() I will then provide instructions for how to create a KVM virtual machine that runs VMware ESXi 6.7, and then smoke test by deploying a guest OS on top of the ESXi hypervisor. In this article, I’ll be using a bare metal server running Ubuntu and KVM as a type 1 hypervisor. Luckily, if you need to test something specific to VMware you can always run ESXi 6.7 nested inside a KVM virtual machine. If you are running KVM on an Ubuntu server, you already have an excellent Type 1 virtualization engine. The resource savings are well worth it for testing purposes.Update Nov 2021: I have written a newer article that deploys ESXi 7.0U1. The only downside is that VMware Tools are not running on these virtual machines, so vSphere will not view the virtual machines as optimal. These virtual machines are small and migrate very quickly with features such as vMotion. For example, many of them are 4 MB of RAM and are PXE boot virtual machines. I create a number of virtual machines that are very, very small. I'm more interested in vCenter features, ESXi configuration, cluster configuration, and other infrastructure features. Here is a tip that I use in my personal lab, for the virtual machines that are running on the virtual ESXi servers I'm not too interested in what is running on those workloads. Be sure to ensure that the LSI Logic Parallel option is selected for the disk controller. If any virtual machines of any significance are to be run on the virtual ESXi server, consider using 4 GB or more for the virtual machine's RAM configuration. ![]() ![]() The new virtual machine wizard will then prompt you to enter the number of virtual CPUs to assign, how much memory to provision, and how many network interfaces to assign to the virtual ESXi server. Configure number of virtual CPUs, memory, network interfaces ![]()
