OpenShift Virtualization Use Cases (Demo Series - Part 1)

KubeVirt technology addresses the needs of development teams that have adopted or want to adopt Kubernetes but possess existing Virtual Machine-based workloads that cannot be easily containerized. More specifically, the technology provides a unified development platform where developers can build, modify, and deploy applications residing in both Application Containers as well as Virtual Machines in a common, shared environment.

The benefits are broad and significant. Teams with a reliance on existing virtual machine-based workloads are empowered to rapidly containerize applications. With virtualized workloads placed directly in development workflows, teams can decompose them over time while still leveraging remaining virtualized components as is comfortably desired.

Red Hat OpenShift Virtualization is a virtualization API and runtime for OpenShift, built on KubeVirt, to run and manage virtual machines using a Kubernetes-native way. We will be looking at the features and functionalities of OpenShift Virtualization in this series of demos. The demo was done on OpenShift 4.11 and the first demo video will focus on the following use cases

1. Overview of OpenShift Virtualization
2. Demo Environment Walk Through
Bare Metal Nodes
Multus Networking (multi-NICs)
OpenShift Virtualization and OpenShift Data Foundation (OCS/ODF) Operator
3. OpenShift Virtualization Tab
Overview (includes information on metrics, VM per template etc)
Catalogs (RHEL and Windows Servers)
Virtual Machines
Templates (Golden Images)
4. Windows Server 2019 Creation
Muli-NICs
Multiple Hard Disks
SCSI Disk Hot Plug
CPU and Memory Expansion
5. Windows Remote Desktop Access to existing Windows Server VM running on OpenShift
6. OpenSSH access to existing RHEL 9 VM
7. PVC Expansion of existing RHEL 8 VM root disk
8. Live Migration of RHEL 8 VM from 1 worker node to another with no traffic disruption, i.e. no loss of packets for ping test towards Google DNS)
