Using oVirt Node with virt-manager

\

Untitled{width=”320” height=”212”}

\ \ Virtualization is already an ubiquitous technique.\ Fedora provides packages for many of the Linux virtualization components through the yum virtualization group.\

$ sudo yum groupinstall virtualization

\ Well, anyway - When doing virtualization you need a host, hosting your virtualized guests. If you don’t want to do this on your local machine - because it hasn’t got the capabilities, isn’t beefy enough, … - you can use oVirt Node as a hypervisor on a second machine which you can easily manage from Fedora using virt-manager.\ This can be useful for a small working group or developers.\ \ oVirt Node is based on Fedora and optimized to quickly get a hypervisor up an running. You actually do not need to care about all the constraints - networking, services, storage, … - you need to consider if you setup a hypervisor yourself (which can also be done with  Fedora). It is also stripped down (~150MB) to preserve most of the RAM and storage space to the virtualized guests.\ \ Anyhow:\

Download oVirt Node

Install it on a machine with a recent Intel or AMD processor

Log into the installed Node using admin and

Configure a network interface

Press F2 to drop to the console and run

/usr/libexec/ovirt-config-password 

  1. set a root password
  2. enable SSH access

Optional: ssh-copy-id your ssh key to node to allow a password-less login

User virt-manager to create a new connection (File -> New Connection) to the installed Node (IP can be found on the Node’s Status page)\ URI: qemu+ssh://$OVIRTNODE/system

($OVIRTNODE needs to replaced accordingly)\ Actually oVirt Node is intended to be used with oVirt Engine, which can manage from one up to a couple of hundreds (?) of Nodes.\ But the Engine setup itself is not as easy as just using virt-manager :)\ At least - Engine would be the next step to get used to the oVirt components.\ \ P.s.: You can use virsh vol-upload to get some data onto the node.
