Virtual machine workloads are migrating to KubeVirt and OpenShift Virtualization at a rapid pace. Understanding how to securely access datacenter networks directly from pods will be critical to a successful migration. Read on to learn how OVN-Kubernetes, NMstate, and Multus work together to enable traditional architecutres in a cloud-native way.
Storing Virtual Machines as Kubernetes resources in git for automated deployment promotes consistency, resilency, and accountability, but commiting secrets to git is risky and should be avoided. Use the External Secrets Operator to securely store cloud-init and other data, and sleep soundly!
Some workloads require the use of VLAN interfaces in virtual machines. VMware calls this feature “Virtual Guest Tagging” or “VLAN Guest Tagging” while OpenStack calls it “VLAN-aware instances”. See how OpenShift Virtualization can pass 802.1q trunks to VMs using a traditional Linux Bridge interface.
OpenShift Virtualization builds upon KubeVirt to provide a container native home for your virtual machine workloads. While bare metal is the only officially support platform today, this post will walk through enabling OpenShift Virtualization on vSphere in a lab environment. With nested virtualization you’ll be able to spin up containerized VMs bridged to your physical networks.
