What Is Xen Hypervisor?
Yes, of course! It's something which is very important that you should know about. Let's talk about Xen, the most popular hypervisor in the virtualization industry. For the benefit of the uninitiated, let's first discuss what a hypervisor is: it's a piece of software that acts as the "boss" of a server, directing the activities of all the "minions" (virtual machines) running on that server. Let's move on to very swiftly to what we have at hand, Xen now. Since it is an open-source type-1 hypervisor that uses the host's hardware directly, it is noticeably faster than type-2 hypervisors (which run on top of a host operating system). One of the cool things about Xen is that it supports live migration of virtual machines, which means that you can copy an active VM from one physical host to another with zero interruption to service. Wow, talk about a seamless change! Para-virtualization is a feature that Xen supports, which is just a fancy name for the fact that the guest OS needs to be tweaked in order to function properly with the hypervisor. However, this tweak improves guest OS performance and interaction with the hypervisor. When it comes to safety, Xen's "Xen security modules" (XSM) provide both the host and the guests with granular permissions. You can think of it as a security guard for your virtual machines. Also, Xen has been around for some time and has been adopted by many companies like Amazon and IBM, making it a #reliable option for business purposes. To recap, Xen is an open-source, type-1 hypervisor that supports live migration of virtual machines, para-virtualization, and advanced security options provided by XSM. A number of large corporations, including Amazon and IBM, have adopted it because of its usefulness in business settings. #xenhypervisor #virtualization #opensource
