To Empower YourData-Center Utilization

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

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

17CloudOpen, August 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


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

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
