In this chapter, we looked at KVM virtual machines and how to create, clone, and migrate when need be. We also looked at some advanced configuration, such as adding a sound device and enabling PCI/GPU passthrough for a KVM VM. By leveraging this cloning technique, we can scale a virtual cluster effortlessly when deploying identical virtual machines. Optional and non-production setup of a nested virtual environment was also explained.
A KVM virtual machine is best practice for all non-Linux operating systems and also when total resource isolation between VMs is mandatory.
In the next chapter, we are going to look at LXC containers in greater detail. We will learn why a Proxmox administrator would choose them over KVM virtual machines.
