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

Large scale, centralized management for server and desktop virtualization

Provide an open source alternative to vCenter/vSphere

Focus on KVM for best integration/performance

Focus on ease of use/deployment

Focus #1 : Performance And Scalability

Maintain a large amount of resources

Data Centers

Storage

Linux Hypervisors

Guests \ VMs

Network

Focus #2 : User Intuitive

Different type of users and requirements

Focus #3 : Secure and Recoverable

It hurts to lose your VM in the cloud

New Host

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.

Prepare Virtual Environment

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

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

• 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

Complete lifecycle management tool for physical and virtual servers.

Provision, Configure and Monitor server.

Something that appears hopelessly complicated, but in actuality is quite simple

Three Steps For Managing Physical Hardware

Provision Initial startup

oVirt Host MgmtProcess

Host Management The process of upgrading content environment for suitable cluster (usually VDSM version upgrade)

● Direct SSH trust obtained.● Allows to retrieve current

installed packages information.● Perform YUM\DNF operations

for specific virst packages.

# Provision New Host

# Gather Errata Information

# Direct Yum Upgrade With oVirt-Host-Mgmt Plugin

Future Plans:

● VM Provisioning● Full Host Configuration Management Through

oVirt● Multiply Selection For Hosts Provisioning ● Upgrade by Katello API● Cluster Upgrades
