Virtualization

In this section, we cover discussion of Fedora virtualization technologies on the @fedora-virt, @fedora-xen-list, @libguestfs, @libvirt-list, @virt-tools-list, and @ovirt-devel-list lists.

Contributing Writer: Dale Bewley

Interviews

Mel Chua recently interviewed[1] Fedora virtualization luminaries Richard Jones, David Lutterkort, and Mark McLoughlin. Topics included:

  • Richard Jones on guestfish and friends (libguestds and libvirt)
  • Mark McLoughlin on virtual upgrades to your virtual machine
  • David Lutterkort on "Network scripts: complex no more!"
  • How to try out virtualization
  • From etherboot to gPXE
  • qcow2: now with better performance!
  • Virtualization in Fedora: a historical retrospective
  • What's Next? Virtualization in F13 and beyond
  • When they're not hacking...

Fedora Virtualization List

This section contains the discussion happening on the fedora-virt list.

Fedora Virtualization Status Report

The latest virt status report[1] from Mark McLoughlin details the status of the latest virtualization related bugs, and relayes behind the scenes drama of "a couple of fire-drills with last-minute serious blocker bugs" as Fedora 12 was about to go out the door.

  1. http://www.redhat.com/archives/fedora-virt/2009-November/msg00045.html

Rawvirt Rawhide Virtualization for Fedora 12

Justin Forbes announced[1] "As was done for Fedora 11 users, the tradition continues, only the locations have changed.

We've set up a repository for people running Fedora 12 who would like to test the rawhide/F13 virt packages. To use it, do e.g."

  $> cat > /etc/yum.repos.d/fedora-virt-preview.repo << EOF
  [rawvirt]
  name=Virtualization Rawhide for Fedora 12
  baseurl=http://jforbes.fedorapeople.org/virt-preview/f12/$basearch/
  enabled=1
  gpgcheck=0
  EOF
  $> yum update

The Virtualization Preview Repository[2] is for people who would like to test the very latest virtualization related packages. This repository is intended primarily as an aid to testing / early experimentation. It is not intended for 'production' deployment.
