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

CloudOpen 2015

Large scale, centralized management for server and desktop virtualization

Provide an open source alternative to vCenter/vSphere

Focus on KVM for best integration/performance

CloudOpen 2015

Focus #1 : Performance And Scalability

Maintain a large amount of resources

Data Centers

Storage

Linux Hypervisors

Guests \ VMs

Network

CloudOpen 2015

Focus #2 : User Intuitive

Different type of users and requirements

CloudOpen 2015

Focus #3 : Secure and Recoverable

It hurts to lose your VM in the cloud

Host DeploymentThe process of preparing an operating systemenvironment 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.

CloudOpen 2015

oVirt Node● Standalone hypervisor

– Small footprint < 100MB

● Customized 'spin' of Fedora + KVM

● 'Just enough' Fedora to run virtual machines

● Runs on all RHEL hardware with Intel VT/AMD-V CPUs

– Easy to install, configure and upgrade

● PXE boot, USB boot, CD or Hard drive

● Upcoming – Using Atomic

Prepare Virtual Environment

21CloudOpen 2015

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

22CloudOpen 2015

• 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

High Availability

23CloudOpen 2015

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
