Which hypervisor best suits your needs for virtualising operating systems?
USEFUL FOR Emulation and virtualisation on servers for more dedicated VMs
KVM is the set of virtualisation modules that are built into the Linux kernel – not a keyboard and mouse switch. The benefit of having KVM built into Linux itself is that it makes it easier to turn it into a dedicated hypervisor, maybe the kind you’d use on a server, without requiring extra layers of packages and other software on top of it. It’s quite quick to set up, especially via a graphical method, and has some good basic functionality between host and guest. It can be used on the command line very easily if you plan to have a headless server.
