How to control a computer remotely?

Administrators primarily use two remote management approaches for controlling computers by leveraging the IP network. The first approach is hardware based KVM Over IP, which utilizes network-enabled KVM switches to provide fast and reliable BIOS-level access - control your computer without as if you were sitting in front of it. The second approach is through the use of cheaper OS based remote access software which provides basic networked access to a PC but has numerous limitations such as if the computer or software locks up you have no way to fix it, and if you need to reboot your computer you will lose your connection.

Can you chain two KVMs together?

Most IP KVMs offer the ability to expand the amount of connected devices by chaining two or more KVM switches together (known as Cascading or Daisy Chaining). Cascading typically requires KVMs to be from the same product family, or to be the same unit. Some switches allow you to remote into all the chained KVMs from one designated 'master' KVM. Please note, in some cases a device port is used for each cascaded KVM switch that is added.

This at least enables you to test your VM settings locally. But local encryption could also be interesting in some multi-user scenarios.
