Type 1 Open Source Hypervisors and More
A hypervisor (also known as a virtual machine monitor) is
computer software that creates and runs virtual machines. The
hypervisor performs the function of controlling
the host processor and resources, determining their allocation to
the guest operating systems. The hypervisor is a very practical way of
getting things virtualized quickly and efficiently.
There are two types of hypervisor. A Type 1 hypervisor
is known as native or bare-metal. With this type, the hypervisor runs
directly on the host's hardware to control the hardware resources and
to manage guest operating systems. In other words, the software
hypervisor does not require an additional underlying operating system.
The second type of hypervisor runs under a conventional
operating system environment as a second layer, with the guest
operating systems then running at the third level. We covered Type 2
hypervisors in this article.
This article identifies the finest open source Type 1
hypervisors that are available to download without charge. We also look
Linux kernel virtualization hypervisors.
VMware vSphere Hypervisor, a stripped-down free version of
ESXi, warrants an honourable mention, but it is released under a
Now, let's explore the 4 hypervisors at hand. For
each title we have compiled its own portal page, a full description
with an in-depth analysis of its features, together with links to
relevant resources and reviews.
