What is a typical use of a Type 2 hypervisor?
There are two types of hypervisors: Type 1 and Type 2. Type 2 hypervisors support guest virtual machines by coordinating calls for CPU, memory, disk, network and other resources through the physical host’s operating system. This makes it easy for an end user to run a virtual machine on a personal computing device.
What file system is the default on Mac OS X computers?

Is KVM a Type 2 hypervisor?
KVM converts Linux into a Type-1 hypervisor. Xen folks attack KVM, saying it’s like VMware Server (the free one that was called “GSX”) or Microsoft Virtual Server because it’s really a Type 2 hypervisor that runs on top of another OS, rather than a “real” Type 1 hypervisor.
Which technology sits on top of a single OS?

Can you also use Docker for running OS?
containers are not for virtualization, and they are using the resources of the host machine. As a result, for now windows container cannot run “as-is” on linux machine. But – you can do it by using VM – as it works on windows. You can install windows VM on your linux host, which will allow to run windows containers.
Can you also use Docker for running OS system containers?
You can run both Linux and Windows programs and excutables in Docker containers. The Docker platform runs natively on Linux (on x86-64, ARM and many other CPU architectures) and on Windows (x86-64). Docker Inc. builds products that let you build and run containers on Linux, Windows and macOS.
Which of these is a containerization technology?
Containers are packages that rely on virtual isolation to deploy and run applications that access a shared operating system (OS) kernel without the need for virtual machines (VMs). Its modern form is expressed in application containerization, such as Docker, and system containerization, such as LXC (Linux Containers).
