Bring your virtualization skills up to date with our Classroom and Online Red Hat OpenShift Virtualization (DO316 | EX316) Training at WebAsha Technologies. This programme teaches you how to run and manage virtual machines on Red Hat OpenShift with the OpenShift Virtualization Operator (KubeVirt). The exam it prepares you for is based on Red Hat OpenShift Container Platform 4.18. In hands-on, performance-based labs you practise the skills tested by the EX316 exam for the Red Hat Certified Specialist in OpenShift Virtualization credential.
Red Hat OpenShift Virtualization training overview:
The DO316 EX316 training covers planning, deploying and operating production-grade VMs on OpenShift. Red Hat's catalogue has listed DO316 as the OpenShift Virtualization Administration Rapid Track Course, which combines the content of DO156 and DO256, and our outline follows those chapters. You install the OpenShift Virtualization Operator, provision and access VMs, and configure networking, storage, backups, live migration and VM imports on an OpenShift cluster. Each short concept session is followed by lab practice for the hands-on EX316 exam.
Intended audience:
This course is for site reliability engineers (SREs), cluster and platform engineers, systems administrators, cloud administrators and cloud engineers who want to run virtual machines on OpenShift and earn a Red Hat certification for it. It also fits virtualization professionals moving away from traditional hypervisors (such as VMware vSphere) to a Kubernetes-native platform.
Topics covered:
-
Deploy OpenShift Virtualization: Install the OpenShift Virtualization Operator through Operator Lifecycle Manager (OLM) and configure it with the HyperConverged resource.
-
Create and access virtual machines: Provision VMs from templates and instance types, and reach them through the web console, virtctl, VNC and SSH.
-
Customise VMs with cloud-init: Add access credentials, configure software repositories and run first-boot commands with cloud-init in VM templates.
-
Configure VM networking: Use Kubernetes networking, Services, Multus CNI, NetworkAttachmentDefinitions and node networking to connect VMs to internal and external networks.
-
Manage VM storage: Configure persistent storage, attach and detach disks, and fill volumes with DataVolumes and the Containerized Data Importer (CDI).
-
Snapshots, clones and templates: Create and restore VM snapshots, clone VMs and disks with DataVolumes, and build custom templates so VMs are provisioned the same way each time.
-
Live migration and node maintenance: Live-migrate VMs with node affinity rules, drain nodes and carry out node maintenance while VMs keep running.
-
Backup and restore with OADP: Deploy the OADP Operator, then back up and restore virtual machines.
-
Import and migrate VMs: Import OVA images and migrate virtual machines from VMware vSphere and Red Hat Virtualization with the Migration Toolkit for Virtualization (MTV).
-
High availability and scheduling: Configure eviction strategies, health probes, watchdog devices, node selectors, affinity, tolerations and taints so VMs survive node failures.
Requirements:
You should be comfortable with the Linux command line and with basic OpenShift/Kubernetes concepts. Online participants need a stable internet connection and a laptop or desktop to join live sessions and reach the OpenShift cloud labs, where most of the EX316 practice happens.
Prerequisites:
For the EX316 exam Red Hat recommends RHCSA-level Linux skills (RH200 or equivalent) and the OpenShift Virtualization Administration courses DO156 and DO256, or equivalent experience. For the faster DO316 Rapid Track course it asks for OpenShift administration skills at the level of DO180 (Red Hat OpenShift Administration I). Earlier work with virtualization or containers helps. Our trainers fill any gaps before the advanced topics.
Career benefits:
With the Red Hat Certified Specialist in OpenShift Virtualization (EX316) credential you can apply for roles such as OpenShift Administrator, Virtualization Engineer, Platform Engineer, SRE and Cloud Infrastructure Specialist. Enterprises are putting VMs and containers on Kubernetes and leaving legacy hypervisors, and certified professionals in India typically earn ₹6 LPA to ₹30+ LPA depending on experience and role. The credential also counts towards the RHCA.
