OpenShift Virtualization networking combines Kubernetes connectivity, guest interfaces, node configuration, and the physical network. This guide follows the packet path, builds a secondary bridge example, and provides a diagnostic sequence for migrated applications that must retain their existing ne
Migration Toolkit for Virtualization (MTV) coordinates discovery, mapping, disk movement, conversion, and target VM creation. Understanding these responsibilities makes it easier to determine whether a failed migration is a provider-access issue, a transfer issue, a conversion issue, or a target-pla
A successful VMware-to-OpenShift migration moves an application service with its data, connectivity, recovery procedures, and ownership. Copying a virtual disk is only one stage. This strategy provides a phased delivery model with measurable acceptance gates and a practical rollback boundary.
KubeVirt adds virtual-machine resources and controllers to Kubernetes. Its most useful operational distinction is between a VirtualMachine, which expresses persistent management intent, and a VirtualMachineInstance, which represents a particular execution of that guest.
OpenShift Virtualization runs virtual machines as managed workloads within OpenShift. Understanding the boundary between the Kubernetes control plane, virtualization controllers, node execution, guest operating systems, and persistent storage makes design and troubleshooting much more precise.
VMware vSphere and Red Hat OpenShift Virtualization can both run enterprise virtual machines, but their management models, operational dependencies, and migration implications differ. The right decision depends on workload requirements and the team’s ability to operate the entire platform, including
🧭 Goal This script configures static network settings (hostname, IP address, subnet, gateway, DNS) automatically on the first boot of a VMware virtual machine. It pulls values passed via VMware’s guestinfo properties and applies them using Netplan. 🛠️ Prerequisites Requirement Description OS Ubuntu 18.04+ (using Netplan) VMware Tools open-vm-tools or equivalent must be installed VMware GuestInfo Settings Must set guestinfo.labvm.* via vSphere or cloud-init 📦 Input Parameters via guestinfo Set the following advanced options in vSphere or through OVF: Key…

We can configure AD LDAP from UI but in case you are looking to configure Identity Source using the command then following is the procesure. Login to VCSA over SSH Switch to shell Navigate path /opt/vmware/lib64/ In case required, you can take a backup of the existing configuration by copying file “/opt/vmware/lib64/vmware-identity-sso-config.jar” Next, you can run the following command to create an identity source
