In the first of our posts on KVM hypervisor management tools we talked about oVirt and today we borrow again vMiss.net article to talk about Red Hat Enterprise Virtualization (RHEV).
RHEV is another set of tools that may be used to manage KVM. It provides features such as live migration of virtual machines and storage, high availability and support for virtual desktop infrastructure.
KVM is a hypervisor included in the main Linux kernel. It is really good as hypervisor, but like all hypervisors, a set of tools is needed to manage it. In this post we talk about one of them, oVirt, thanks to this article written by vMiss.net
oVirt is a set of Open Source management tools that runs on different Linux distributions. It has interesting enterprise features, such as high availability, load balancing, and support for local and shared storage. In addition, the new oVirt 3.5 features include the merge of multiple snapshots and the introduction of Optaplanner, that allows to check if a virtual machine can be within a cluster when a user attempts to deploy it on a server that does not have enough resources.
The formula to get rid of proprietary systems to deploy a desktop virtualization platform, the new operating systems supported by UDS Enterprise and OpenSUSE 13.2 in KDE or Gnome desktops have been the most interesting topics for our readers during the last two weeks.

How to deploy a fully Open Source virtual platform
There are Linux-based (either Debian, SUSE or, of course, Red Hat) desktop virtualization solutions which are fully Open Source. Any modern version of a Linux distribution incorporates support for KVM, so if your hardware allows it, it turns the operating system into a hypervisor platform. On this basis we install oVirt, which will be responsible for transforming the Linux into a node of our virtualization system.
Finally, we will need a virtual desktop management platform as UDS Enterprise, which has a fully Open Source version and, in the same way as Red Hat, there is the possibility of hiring support, updates, patches and maintenance.
Our team’s tips to make the most of the new version of oVirt and the creation and management of virtual classrooms with KVM have been the most read topics in our blog for the last weeks.

How to make the most of oVirt 3.5
At the end of a class, each student has changed many aspects of virtual machines (VM). In order to prepare them for the next class, it is important to be able to return them to its original state as soon as possible. The Logical Volume Manager snapshots are useful in these cases.
The Logical Volume Manager (LVM) is a method that has been used successfully on Linux for many years and managing storage in a flexible way. Instead of working with fixed storage allocation units, LVM work with versatile volumes that can be extended or reduced very easily. These volumes offer also other benefits, like the snapshots.
