How VM is started

Starting up a virtual machine (VM) is not an easy task, there are a lot of things going on hidden from the plain sight and studying it alone is a challenging task. The goal of this post is to simplify the process of learning how the oVirt hypervisor works. The concept of the oVirt is illustrated in the process of starting up the VM, which covers everything from top to the bottom.

oVirt Now Supports OVS-DPDK

DPDK (Data Plane Development Kit) provides high-performance packet processing libraries and user space drivers. Open vSwitch uses DPDK libraries to perform entirely within the user space. According to Intel ONP performance tests, using OVS with DPDK can provide a huge performance enhancement, increasing network packet throughput and reducing latency.

OVS-DPDK has been added to the oVirt Master branch as an experimental feature. The following post describes the OVS-DPDK installation and configuration procedures.

oVirt Webadmin GWT Debug Quick Refresh

As a developer, one drawback of using Google Web Toolkit (GWT) for the oVirt Administration Portal (aka webadmin) is that the GWT compile process takes an exceptionally long time. If you make a change in some code and rebuild the ovirt-engine project using make install-dev ..., you'll be waiting several minutes to test your change. In practice, such a long delay in the usual code-compile-refresh-test cycle would be unbearable.

Integrating Kibana/Elasticsearch on Top of OpenShift with oVirt Engine SSO

oVirt Engine provides a powerful way to manage users and domains using the oVirt Engine AAA extensions. oVirt Engine supports many different LDAP server types for authentication using the ovirt-engine-extension-aaa-ldap extension and supports managing internal users using the ovirt-engine-extension-aaa-jdbc extension. Clients can use the powerful oVirt Engine user management in their applications by using the OAuth2 or OpenId Connect end points provided by oVirt Engine SSO to authenticate users in their applications.

Below is step-by-step instructions on how to integrate Kibana/Elasticsearch on top of OpenShift with oVirt Engine SSO. The instructions should work for any client application that can be configured to use a OAuth2 or OpenID Connect server to authenticate its users.

A Warm Welcome to the Summer Internship Students

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.
