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

compared to Fedora 12.
FWN<ref>http://fedoraproject.org/wiki/FWN/Issue175#libguestfs_on_non-Fedora_Platforms</ref> when asking if
 
[[RichardJones|Richard Jones]]
 
would consider including {{package|qemu}}-0.10 into {{package|libguestfs}} package to satisfy dependencies for Fedora 10.
 
 
 
Richard "had a go at backporting the changes to <code>qemu</code> that we ship in
 
F-10.  <code>qemu</code> in F-10 is based on <code>qemu</code> 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 <code>libguestfs</code><ref>http://koji.fedoraproject.org/koji/search?match=glob&type=package&terms=libguestfs</ref> and/or <code>qemu</code><ref>http://koji.fedoraproject.org/koji/search?match=glob&type=package&terms=qemu</ref> 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
+
[[DanielBerrange|Daniel Berrange]]
<code>libguestfs</code> .
+
explained<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00040.html</ref>
 +
"The KVM based virtualization in RHEL-5.4 is not nearly so far behind
 +
Fedora as you might think. The {{package|libvirt}} mgmt stack in RHEL-5.4 was
 +
rebased to be near parity with [[Releases/11|Fedora 11]], and KVM in RHEL-5.4 is
 +
also pretty close to that using what's best described as a hybrid of
 +
kvm-83 and kvm-84."

==== New Release virt-inspector ====
 
[[RichardJones|Richard Jones]]
 
announced<ref>http://www.redhat.com/archives/fedora-virt/2009-May/msg00073.html</ref>
 
"the first 'really working' version of <code>virt-inspector</code><ref>http://git.et.redhat.com/?p=libguestfs.git;a=summary
 
</ref>."
 
 
"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.

having "a subgoal is to extend the driver base of {{package|libvirt}}. We've
 
started an VMware ESX driver and are investigating Hyper-V support."
 
 
 
"The ESX driver isn't complete yet, currently it supports:"
 
* domain lookup by ID, UUID and name
 
* domain listing
 
* domain suspend and resume
 
* domain reboot, if the VMware tools are installed inside the domain
 
* domain start and shutdown
 
* domain migration
 
 
 
"We think this code might be useful for others and would be glad if the
 
driver could be merged into libvirt in medium term." Matthias was met with enthusiasm from the core <code>libvirt</code> developers.

Virtualization

In this section, we cover discussion of Fedora virtualization technologies on the @fedora-virt list.

Contributing Writer: Dale Bewley

Fedora Virtualization List

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

Virt Status Report

Justin Forbes posted[1] a Fedora virtualization status report. Justin pointed out F13 bugs[2] now include Important and Pony classifications in addition to Blocker and Target.

RHEL and Fedora Virtualization Feature Parity

Robert Day wondered how the virtualization features[1] of Red Hat Enterprise Linux 5.4 compared to Fedora 12.

Daniel Berrange explained[2] "The KVM based virtualization in RHEL-5.4 is not nearly so far behind Fedora as you might think. The Package-x-generic-16.pnglibvirt mgmt stack in RHEL-5.4 was rebased to be near parity with Fedora 11, and KVM in RHEL-5.4 is also pretty close to that using what's best described as a hybrid of kvm-83 and kvm-84."
