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.

  • Virt 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, confjgure and upgrade

  • PXE boot, USB boot, CD or

Hard drive

  • Upcoming – Using Atomic

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

slide-20
SLIDE 20

22

CloudOpen 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

CloudOpen 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
