is kvm a bare metal hypervisor?

How does KVM work? KVM converts Linux into a type-1 (bare-metal) hypervisor. All hypervisors need some operating system-level components—such as a memory manager, process scheduler, input/output (I/O) stack, device drivers, security manager, a network stack, and more—to run VMs.

Type 1: Native Hypervisors run directly on the host machine, and share out resources (such as memory and devices) between guest machines. Type 2: Hosted Hypervisors run as an application inside an operating system, and support virtual machines running as individual processes.

Windows 10 Home edition doesn't support Hyper-V feature, it can only be enabled on Windows 10 Enterprise, Pro, or Education. If you want to use virtual machine, you need to use third-party VM software, such as VMware and VirtualBox. ... Features required for Hyper-V will not be displayed.

VT-x is Intel's technology for virtualization on the x86 platform. ... Make sure Virtualization is enabled in your BIOS. To check the status of Hyper-v in Windows 10,<right click start> | Run | OptionalFeatures.exe, and look for the "Hyper-V" option.

libvirt is an open-source API, daemon and management tool for managing platform virtualization. It can be used to manage KVM, Xen, VMware ESXi, QEMU and other virtualization technologies. These APIs are widely used in the orchestration layer of hypervisors in the development of a cloud-based solution.

Hyper-V allows administrators to create virtual instances and virtual environments in isolation which facilitates efficient creation and management of more than one virtual server on the same set of machine hardware at the same time. ESXi is a type-1 hypervisor designed by VMware.

VDI hosts desktop environments on a centralized server and deploys them to end-users on request. In VDI, a hypervisor segments servers into virtual machines that in turn host virtual desktops, which users access remotely from their devices. ... VDI can be either persistent or nonpersistent.

KVM and VirtualBox supposedly cannot coexist, or rather, VirtualBox won't run while the KVM modules are loaded in memory. KVM can work fine alongside VirtualBox, so it's a one-way problem, really.

Hyper-V Server is a standalone product which only includes roles related to virtualization. It is free and includes the same hypervisor technology in the Hyper-V role on Windows Server 2019. ... For remote management you can use Free Windows admin center (WAC) which is a separate download.

A Type 2 hypervisor, also called a hosted hypervisor, is a virtual machine manager that is installed as a software application on an existing operating system (OS).

Basically, KVM is a type-2 hypervisor (installed on top of another OS, in this case some flavor of Linux). It runs, however, like a type-1 hypervisor and can provide the power and functionality of even the most complex and powerful type-1 hypervisors, depending on the tools that are used with the KVM package itself.

The Xen Project hypervisor is an open-source type-1 or baremetal hypervisor, which makes it possible to run many instances of an operating system or indeed different operating systems in parallel on a single machine (or host). The Xen Project hypervisor is the only type-1 hypervisor that is available as open source.

The main difference between Type 1 and Type 2 hypervisors is that Type 1 runs on bare metal and Type 2 runs on top of an OS. ... The physical hardware that a hypervisor runs on is typically referred to as a host machine, whereas the VMs the hypervisor creates and supports are collectively called guest machines.

Kvm will be faster. It should operate as a type 1. Virtualbox is a type 2 and will have to emulate instructions on lower protection rings.

So to conclude: QEMU is a type 2 hypervisor that runs within user space and performs virtual hardware emulation, whereas KVM is a type 1 hypervisor that runs in kernel space, that allows a user space program access to the hardware virtualization features of various processors.
