==== '''virt-what''' Script Detects Running in a Virtual Machine ====
[[RichardJones|Richard W.M. Jones]] announced[1] version 1.0 of [http://et.redhat.com/~rjones/virt-what/ | virt-what] which is a simple shell script that detects if you are running inside a virtual machine, and prints some "facts" about that virtual machine.

==== Xen 3.3.0 Released ====
[[PasiKärkkäinen|Pasi Kärkkäinen]] forwarded[1] from xen-devel an announcement
of Xen 3.3.0. Pasi also followed up[2] on a thread from July where [[DanielBerrange|Daniel P. Berrange]] said about Fedora 10, "Even though we don't have any Dom0 I'll update it to 3.3.0 for the xen RPM and hypervisor. This will at least let people build their own legacy Xen kernel from upstream's 2.6.18 xen kernel"

==== Live Migration Sanity Checks ====
Contributing Writer: [[User:Dale | Dale Bewley]]
[[ChrisLalancette|Chris Lalancette]] described[1] a feature that oVirt would
like to see. The feature would be a set of sanity checks a caller could make
to determine if live migration of a given virtual machine would be likely to
succeed.

"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."


==== Exposing Unique Hypervisor Features ====
<references />
Nguyen Anh Quynh asked[1] how libvirt can expose the unique features of a
given hypervisor such as the monitor interface of Qemu. [[DanielBerrange|Daniel P. Berrange]] responded[2] by stating the policy for adding new APIs to libvirt is that the conceptual representation has to be applicable to multiple hypervisors and unique concepts may be exposed if they can be represented in a way which
would also make sense for other hypervisors in the future. This goal is also stated in the libvirt architecture [http://libvirt.org/intro.html document].

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."
