- 5. 5 Red Hat OpenShiftVirtualization Red Hat OpenShift Virtualization Red Hat OpenShift Container Platform Red Hat Enterprise Linux Physical machine VMs Containers ▸ Included capability of the Red Hat OpenShift application platform ▸ Built on KubeVirt Top 10 CNCF active project ▸ Unified application platform Consistent management, tooling, diverse ecosystem ▸ Performance and stability The industry standard Kernel Virtual Machine (KVM) hypervisor ▸ Includes Red Hat Enterprise Linux guest entitlements ▸ Supports Microsoft Windows guests Microsoft Server Virtualization Validation Program (SVVP) Modern virtualization option for general purpose virtualization customers
- 6. Containers are notvirtual machines 6 Infrastructure Operating System App 1 App 3 App 2 Hypervisor Guest OS Guest OS Guest OS Infrastructure Virtualization Containerization App 1 App 3 App 2 ● Containers are process isolation ● Kernel namespaces provide isolation and cgroups provide resource controls ● No hypervisor needed for containers ● Contain only binaries, libraries, and tools which are needed by the application ● Ephemeral
- 7. Virtual machines canbe put into containers 7 ● A KVM virtual machine is a process ● Containers encapsulate processes ● Both have the same underlying resource needs: ○ Compute ○ Network ○ (sometimes) Storage
- 8. OpenShift Virtualization 8 ● Virtualmachines ○ Running in containers, managed as Pods ○ Using the KVM hypervisor ● Scheduled, deployed, and managed by Kubernetes ● Integrated with container orchestrator resources and services ○ Traditional Pod-like SDN connectivity and/or connectivity to external VLAN and other networks via multus ○ Persistent storage paradigm (PVC, PV, StorageClass)
- 9. OpenShift Virtualization usesKVM 9 ● OpenShift Virtualization uses KVM, the Linux kernel hypervisor ● KVM is a core component of the Red Hat Enterprise Linux kernel ○ KVM has 10+ years of production use: Red Hat Virtualization, Red Hat OpenStack Platform, and RHEL all leverage KVM, QEMU, and libvirt ● QEMU uses KVM to execute virtual machines ● libvirt provides a management abstraction layer ● Currently supported on x86 bare metal ● For other platforms contact Product Management for roadmap HARDWARE RHCOS KVM CPU/RAM STORAGE NETWORK DRIVER DRIVER DRIVER OTHER APPS QEMU libvirt
- 10. Containerized virtual machines 10 Kubernetesresources ● Every VM runs in a launcher pod. The launcher process will supervise, using libvirt, and provide pod integration. Red Hat Enterprise Linux ● libvirt and qemu from RHEL are mature, have high performance, provide stable abstractions, and have a minimal overhead. Security - Defense in depth ● RHCOS has controlled configuration by default, SELinux MCS, plus KVM isolation - inherited from the Red Hat portfolio stack Storage Network CPU Memory Device
- 11. Using VMs andcontainers together 11 ● Virtual machines connected to SDN networks are accessible using standard Kubernetes methods: ○ Service, Route, Ingress ○ Service Mesh ○ Pipelines ● Network policies apply to VM pods the same as application pods ● VM-to-Pod, and vice-versa, communication happens over SDN or ingress depending on network connectivity

Accelerating Planning Pain Points How can Red Hat work with you to devise a longer term plan for virtualization? Timelines and Objectives Current plans and discussion What commitments and objectives are we marching toward for migration based on the planned General Availability date?
- 15. Whether for strategy, implementation,migration or operational advice, Red Hat Services meets customers where they are on their infrastructure modernization journey, enabling them to migrate and manage their virtual machines with OpenShift Virtualization. Customers can preserve their existing infrastructure and vm investments while taking advantage of the simplicity and speed of a comprehensive hybrid cloud platform.
