announced<ref>http://www.redhat.com/archives/fedora-virt/2009-April/msg00220.html</ref> release 1.0.10 of {{package|libguestfs}}<ref>http://et.redhat.com/~rjones/libguestfs/</ref>
posted<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00056.html</ref> a Fedora virtualization status report.  
Born only a couple of weeks ago(FWN#171<ref>http://fedoraproject.org/wiki/FWN/Issue171#Guest_Configuration_with_augeas_and_libguestfs</ref>), <code>libguestfs</code> has progressed very far very fast.
Justin pointed out F13 bugs<ref>http://fedoraproject.org/wiki/Virtualization_bugs</ref> now include Important and Pony classifications in addition to Blocker and Target.


"<code>libguestfs</code> is a library for accessing and modifying guest disk images. Amongst the things this is good for: making batch configuration changes to guests, getting disk used/free statistics (see also: {{package|virt-df}}), migrating between virtualization systems (see also: virt-p2v), performing partial backups, performing partial guest clones, cloning guests and changing registry/UUID/hostname info, and much else besides."

"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."

a new experimental dom0 kernel "version (2.6.30-0.1.2.21.rc3.xendom0.fc12) is based on the Fedora devel kernel branch and xen-tip/next branch from the pvops kernel repository."
This kernel may be found in Michael's yum repo<ref>http://fedorapeople.org/~myoung/dom0/</ref>.
Michael added that "very few xen patches made it into 2.6.30, just bugfixes and tidy ups, so we are waiting at least until 2.6.31<ref>http://lists.xensource.com/archives/html/xen-devel/2009-04/msg00961.html</ref> for mainline dom0 support."

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."
