A futottak még virtualbox, kvm, stb meg type-2. Ez nekem mindent elmond :D
One interesting technology is the KVM hypervisor. This open sourced Linux-based hypervisor is mostly classified as a Type-1 hypervisor, which turns the Linux kernel into a “bare metal” hypervisor. At the same time, the overall system is categorised as a type-2 hypervisor due to the full functional Operating System used. The unique KVM model allows for full virtualization and customized kernels (the core component of computer operating systems), allowing you the opportunity to set limits for the resources used, it also ensures that your virtual machines are more isolated and can host different Operating Systems other than Linux.
