The ESXi command esxcli has many namespaces and options to choose from. It may sometimes be hard to find what the exact command is to perform a task. You can of course use a search engine to find what you need. But with this practical tip you can also find what you need with the esxcli command itself.
First let's have a look at the command itself. When you execute the command without any parameters it will show the possible options and namespaces.
When a virtual machine is migrated from one ESXi host to another the traffic for that vm has to be delivered to the destination host and no longer to the source host. How is the physical switch informed about the move? ESXi sends out a Reversed Address Resolution packet on the destination host that will trigger the physical switch to update its MAC-address table. In this article I will explain how this process works and why it is important.
When using the vSphere Client it is only possible to export a virtual machine as a template in OVF-format. Exporting in OVA-format is not supported at the moment. This functionality has been removed since vSphere 6.5 (documentation).
It is however possible to export a virtual machine in the OVA-format with the VMware OVFtool via the command line.
In February 2024, shortly after the acquisition for VMware by Broadcom, VMware has removed their free hypervisor ESXi from their website.
