In this chapter we looked at KVM Virtual Machines, how to create them, clone them, and migrate them when need. We also looked at some advanced configuration such as adding a sound device and enabling pci/gpu passthrough for KVM VMs. By leveraging cloning techniques 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.
KVM virtual machine are a 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.
