What is Proxmox
Promox VE
Proxmox Virtual Environment is an open source server virtualization management solution based on QEMU/KVM and
LXC. You can manage virtual machines, containers, highly available clusters, storage and networks with an integrated, easy-
to-use web interface or via CLI. Proxmox VE code is licensed under the GNU Affero General Public License, version 3. The
project is developed and maintained by Proxmox Server Solutions GmbH
What is a hypervisor?
A hypervisor is software that pools computing resources—like processing, memory, and storage—and reallocates them
among virtual machines (VMs). This technology makes virtualization possible, meaning you can create and run many
VMs from a single physical machine.
The hypervisor gives each virtual machine the resources that have been allocated and manages the scheduling of VM
resources against the physical resources. The physical hardware still does the execution, so CPU is still executing CPU
instructions as requested by the VMs, for example, while the hypervisor manages the schedule.
Multiple different operating systems can run alongside each other and share the same virtualized hardware resources
with a hypervisor. This is a key benefit of virtualization. Without virtualization, you can only run 1 operating system on the
hardware.
Types of hypervisors
There are 2 different types of hypervisors that can be used for virtualization: type 1 and type 2 hypervisors.
Type 1
A type 1 hypervisor, also referred to as a native or bare metal hypervisor, runs directly on the host’s hardware to manage guest operating systems. It takes the
place of a host operating system and VM resources are scheduled directly to the hardware by the hypervisor.
This type of hypervisor is most common in an enterprise data center or other server-based environments.
KVM, Microsoft Hyper-V, Proxmox, and VMware vSphere are examples of a type 1 hypervisor. KVM was merged into the Linux kernel in 2007, so if you’re using a
modern version of Linux, you already have access to KVM.
Type 2
A type 2 hypervisor is also known as a hosted hypervisor, and is run on a conventional operating system as a software layer or application.
It works by abstracting guest operating systems from the host operating system. VM resources are scheduled against a host operating system, which is then
executed against the hardware.
A type 2 hypervisor is better for individual users who want to run multiple operating systems on a personal computer.
VMware Workstation and Oracle VirtualBox are examples of a type 2 hypervisor.
