The big new features:
The Administration Portal has been redesigned using Patternfly, a widely adopted standard in web application design that promotes […]
Now oVirt features a simple way to prevent a host from scanning and then activating logical volumes that are not required directly by the host. In particular, the solution addresses logical volumes on shared storage managed by oVirt, and logical volumes created by a guest in oVirt raw volumes. Why is a solution required? Because scanning and activating other logical volumes may cause data corruption, slow boot, and other issues.
The solution is configuring an LVM filter on each host, which allows LVM on a host to scan only the logical volumes required directly by the host. To achieve […]
on November 8, oVirt 4.2 saw the introduction of an important behind-the-scenes enhancement.
The change is associated with the exchange of information between the engine and the VDSM. It addresses the issue of multiple abstraction layers, with each layer needing to convert its input into a suitably readable format in order to report to the next layer.
This change improves data communication between the engine and Libvirt – the tool that manages platform virtualization.
Background
Previously, the configuration file for a newly created virtual machine (VM) originated in the engine as a map or dictionary.
Then, […]

The oVirt project is glad to announce that five talented students will be joining the oVirt community over the summer period, as part of the 2017 Google Summer of Code (GSoC) and Outreachy internship programs.
Both GSoC and Outreachy focus on getting more student developers interested in open source software development, as well as providing opportunities for talented people, underrepresented in the tech world, to gain valuable technology experience. The students will spend their summer break writing code, learning about open source development and documentation, and earning a stipend.
Joining us as part of GSoC are:
