1 Integrating ovirt, Foreman And Katello To Empower Your Data-Center Utilization Yaniv Bronhaim Senior Software Engineer, RHEV Red Hat IL, Raanana August 2015, CloudOpen Europe

2 Agenda Introducing Open-Source solutions ovirt, Foreman and Katello New third-party integration in ovirt 3.6 Using Foreman for Bare-Metal Provisioning Using Katello for displaying Errata (update) content information for hosts, Vms and Engine ovirt 3.6 Upgrade Manager ovirt 4.0 plans

3 Large scale, centralized management for server and desktop virtualization Provide an open source alternative to vcenter/vsphere Focus on KVM for best integration/performance

4 Focus #1 : Performance And Scalability Maintain a large amount of resources Data Centers Linux Hypervisors Network Storage Guests \ VMs

5 Focus #2 : User Intuitive Different type of users and requirements

6 Focus #3 : Secure and Recoverable It hurts to lose your VM in the cloud

7 Data Centers Linux Hypervisors Network Storage Guests \ VMs

10 Host Deploy The Basic Of Utilizing The Hypervisor Engine Client (Web Portal)

11 Deploy Host Flow Engine Client (web portals)

12 New Host Deploy (Configure)

13 Host Deployment The process of preparing an operating system environment suitable to host virtual machines and to be managed by the ovirt back-end VDSM packages are installed. Clock is 'soft' synchronized. Management bridge created. Firewall rules applied. SSH trust obtained. PKI trust obtained. VDSM certificate issued. Services' boot state set. Host tuned for virtualization.

14 ovirt Node Standalone hypervisor Small footprint < 100MB 'Just enough' Fedora to run virtual machines Runs on all RHEL hardware with Intel VT/AMD-V CPUs Easy to install, configure and upgrade Customized 'spin' of Fedora + KVM PXE boot, USB boot, CD or Hard drive Upcoming Using Atomic

18 Prepare Virtual Environment

19 Live Migration Dynamically move virtual machines between hosts No service interruption Applications continue to run Migrate even I/O intensive workloads such as databases Perform hardware maintenance without application downtime Dynamically balance workloads between host systems 21

20 High Availability Build a highly available enterprise infrastructure Continually monitor host systems and virtual machines Automatically restart virtual machines in case of host failure Restart virtual machine on another node in the cluster Use live migration to fail-back a VM to it's original host when the server is restored 22

21 System Scheduler Dynamically balance workloads in the data center. Automatically live migrate virtual machines based on resources Define custom policies for distribution of virtual machines Define policies to optimize workload on a fewer number of servers during off-peak hours 23
