Rawhide Virtualization Repository

Mark McLoughlin announced[1] the launce of the virt preview repo(FWN#171[2]). "We've set up a repository for people running Fedora 11 who would like to test the rawhide/F12 virt packages. To use it, do e.g."

  $> cat > /etc/yum.repos.d/fedora-virt-preview.repo << EOF
  name=Virtualization Rawhide for Fedora 11
  $> yum update

Adding "this is very much a work-in-progress."

Mark McLoughlin decribed[3] the different types of users consuming these packages:

  • 1) Users who want things to stay stable and who aren't necessarily expecting new features until they update to F-12 - these are people with just the updates repo enabled
  • 2) Same as (1) but who are willing to help out testing updates for the whole distro in order to catch things before they hit the people in category (1) - these people have the updates and updates-testing repos enabled
  • 3) Mostly the same as (1) or (2), but have a specific interest in testing new virt features and are willing to deal with virt regressions - these people enable the updates, updates-testing and preview repos
  • 4) People who are interested in helping with helping with F-12 development in general, not just virt - these people run rawhide

Daniel Berrange added[4] "The virt-preview repo is intended primarily as an aid to testing / early experimentation. It is not intended for 'production' deployment."

No libguestfs on Fedora 10

Ján ONDREJ referenced[1] FWN[2] when asking if Richard Jones would consider including Package-x-generic-16.pngqemu-0.10 into Package-x-generic-16.pnglibguestfs package to satisfy dependencies for Fedora 10.

Richard "had a go at backporting the changes to qemu that we ship in F-10. qemu in F-10 is based on qemu 0.9, and doesn't include the vmchannel patch." But "ended up with a qemu which compiled, but kept segfaulting, and it was tricky to diagnose exactly why."

"Is it really a problem to use the libguestfs[3] and/or qemu[4] packages from Fedora 11 builds? You can grab the latest builds out of Koji." "This worked OK for me, although I have now moved to using Fedora 11-Preview, and have mostly abandoned Fedora 10."

Daniel B and Mark Mc concurred, Fedora 11 is the place to get libguestfs .

New Release virt-inspector

Richard Jones announced[1] "the first 'really working' version of virt-inspector[2]."

"This is a tool based around libguestfs which can inspect a virtual machine disk image and tell you some interesting things about what's inside it."

Some of the things virt-inspector can tell you:

  • What operating system(s) are installed, and what distros and versions. It currently covers RHEL releases, Fedora releases, Debian releases, and has limited support for Windows.
  • How disk partitions are expected to be mounted (eg. /dev/sda1 -> /boot)
  • What applications are installed.
  • What kernel(s) are installed.
  • What kernel modules are installed.

Fedora Xen List

Xen 3.4.0 Released

Pasi Kärkkäinen forwarded[1] an announcement from the Xen list.

"This release contains a number of important new features and updates including:

  • Device passthrough improvements, with particular emphasis on support for client devices (further support is available as part of the XCI project[2])
  • RAS[3] features: cpu and memory offlining
  • Power management - improved frequency/voltage controls and deep-sleep support. Scheduler and timers optimised for peak power savings.
  • Support for the Viridian (Hyper-V) enlightenment interface
  • Many other x86 and ia64 enhancements and fixes

Fedora 11 includes Package-x-generic-16.pngXen version 3.3.1.
