OpenShift & KubeVirt Setup

@jack9603301

I have experience building virtual machines with libvirt, although I really haven't used OpenShift. If you need it, I can provide you with this kind of service and test it in a nested virtual machine environment in my home lab, and provide you with deployment services to ensure that everything is foolproof. If you have any questions, please contact me, thank you!

Hi, I can deploy a production-ready OpenShift cluster (3 masters + 3 workers) and integrate KubeVirt to run both Linux and Windows VMs within the same environment. I’ve worked on Kubernetes/OpenShift setups with virtualization layers, focusing on stability, networking, and clean resource isolation. Approach: * Provision and configure OpenShift cluster (HA control plane, worker nodes) * Set up networking, storage classes, and security policies * Install and configure KubeVirt (CRDs, operators, networking) * Enable virtualization workloads alongside containers * Deploy and validate Linux & Windows VMs (images, drivers, networking) * Configure resource allocation, scaling, and monitoring I’ll ensure: * Stable cluster with proper HA setup * Seamless coexistence of containers + VMs * Secure and well-documented configuration Deliverables: * Fully working OpenShift cluster (3+3 nodes) * KubeVirt integrated and operational * Linux & Windows VMs running and accessible * Documentation for management and scaling I have 15+ years of experience in DevOps, Kubernetes, and infrastructure design. Timeline: 3–5 days Quick questions: On-prem or cloud deployment? Preferred storage (Ceph/NFS/other)? Ready to start immediately. Regards, Rahul

OpenShift's installer has almost no tolerance for DNS or NTP misconfiguration. A single missing SRV record or clock drift over 500ms will stall the bootstrap before a node joins the cluster. My plan is to front-load that work: cluster DNS (api, api-int, wildcard ingress), a load balancer for the API and ingress VIPs, pull secrets validated against your registry, and NTP confirmed across all six nodes before the installer runs. From there, UPI or IPI depending on your hardware, operators validated green, CSRs approved, ingress confirmed reachable. Then KubeVirt operator in, storage class pinned for VM disks, sample VM booted end-to-end. MachineConfig for SR-IOV or hugepages only if your workloads actually need it. You'd also get a short runbook covering cluster upgrades and node replacement so day-2 ops aren't a scramble. M1: Infra prereqs (DNS, LB, NTP, pull secrets), INR 3,250, 3d. M2: OCP cluster install + validation (operators green, ingress reachable), INR 3,250, 4d. M3: KubeVirt operator + sample VM boot + storage class, INR 3,250, 4d. M4: Runbook + handover, INR 3,250, 3d. What's your setup, bare metal or VMs on a hypervisor? That determines the install method and the network plumbing specifics.

Successfully deploying OpenShift with a 3-master, 3-worker node cluster and integrating KubeVirt for mixed OS VM support presents a focused challenge in orchestration and virtualization. I've previously configured similar OpenShift environments, including integrating virtualization layers for diverse workloads, and I’m confident in delivering this setup. My approach will prioritize a clean, repeatable deployment using infrastructure-as-code principles to ensure stability and maintainability, specifically focusing on the KubeVirt configuration to handle both Linux and Windows VMs as you’ve requested. I anticipate completing the core OpenShift and KubeVirt deployment within 5-6 days, with the final day dedicated to testing and documentation.

Hello. I will install OpenShift on linux instances with 3 master and 3 worker nodes. The instances will run on docker containers which means VM is not required. Kind regards,

Hi, I'm a CKA/CKAD-certified Kubernetes engineer with 10+ years in infrastructure, including multi-node cluster management, GPU workloads, and complex multi-tenant environments. OpenShift is built on upstream Kubernetes and I'm familiar with its tooling (OCP installer, MCO, oc CLI) and KubeVirt for running VMs alongside containers. My approach for your setup: - Deploy a 3-master/3-worker HA cluster via OCP IPI/UPI installer - Install OpenShift Virtualization operator (Red Hat's KubeVirt distribution), configure HyperConverged CR and CDI for VM disk management - Set up Linux VMs via cloud-init DataVolumes and Windows VMs with virtio drivers and sysprep config - Configure Multus CNI for advanced VM networking if needed Before starting, I'd need to clarify: - Underlying infrastructure (bare metal, VMware, or cloud)? - RHEL subscription / OCP pull secret available? - Storage backend (Ceph, NFS, local disks)? Happy to discuss scope and timeline. Let me know if you have questions. Best, Jaber
