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."
$> cat > /etc/yum.repos.d/fedora-virt-preview.repo << EOF [rawvirt] name=Virtualization Rawhide for Fedora 11 baseurl=http://markmc.fedorapeople.org/virt-preview/f11/$basearch/ enabled=1 gpgcheck=0 EOF $> 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

FWN[2] when asking if
Richard Jones
would consider including 
qemu
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.
