Integrating oVirt, And Katello To Empower Your Data-Center Utilization

Yaniv Bronhaim Senior Software Engineer, Maintainer @ RHEV

Red Hat IL, Raanana August 2015, CloudOpen NA CloudOpen, August 2015 Abstract Agenda: ● Introduction to oVirt, Foreman and Katello ● Integration with oVirt ● Using Foreman in for Bare- Metal provisioning ● Using Katello for displaying Errata (update) information ● Upgrade Manager in oVirt ● Future Plans ● Summary

CloudOpen, August 2015 Large scale, centralized management for and desktop Provide an open source alternative to vCenter/vSphere Focus on KVM for best integration/performance Focus on ease of use/deployment

● VDSM packages are installed. ● Clock is 'soft' synchronized. ● Management bridge created. ● rules applied. ● SSH trust obtained. ● PKI trust obtained. ● VDSM certificate issued. ● Services' boot state set. ● Host tuned for virtualization.

CloudOpen, August 2015 Prepare Virtual Environment

CloudOpen, August 2015 • Dynamically move virtual machines between hosts

● No service interruption

● Applications continue to run • Migrate even I/O intensive workloads such as • Perform hardware maintenance without application downtime • Dynamically balance workloads between host systems

CloudOpen, August 2015 17 • Dynamically balance System Scheduler workloads in the . • 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

CloudOpen, August 2015 18 • Build a highly available enterprise infrastructure • Continually monitor host systems and virtual machines • Automatically restart virtual machines in case of host failure

● Restart on another node in the cluster • Use live migration to “fail-back” a VM to it's original host when the server is restored
