"instructions on how to install a bare SELinux policy for {{package|cobbler}}. Feedback in the form of AVC denials would be appreciated so that we can perfect this bare policy."
 
[[MichaelDeHaan|Michael DeHaan]] asked[2]
"Would someone like to take a shot at refining this policy some or at least
running Cobbler with that for a while (in permissive mode) to identify what
else needs to be allowed?" and added the policy to the cobbler wiki[3].

==== New Fedora Virtualization List ====
==== Virt Status Report ====
On @fedora-xen, [[DanielVeillard|Daniel Veillard]] announced[1] the creation of the new @fedora-virt list.
[[JustinForbes|Justin Forbes]]
 
posted<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00056.html</ref> a Fedora virtualization status report.  
"As the initiator for [the fedora-xen] list, I must admit I made a mistake
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.
3 years ago, I should have picked a list name agnostic from the
hypervisor name. With the current state of Xen in Fedora recent
releases it really make sense to try to correct that mistake ...
it's never too late ! So
http://www.redhat.com/mailman/listinfo/fedora-virt
is born, I don't want to mass-subscribe people, especially as
I think the current list should survive with its Xen centric
focus. You can subscribe directly to the new URL above.
 
The topic is everything concerning Fedora and virtualization
including Xen.
 
I think the [fedora-xen] list would be a good place for people
still using Fedora <= 8 with Xen, but it's just a suggestion :-)"
 
And on @et-mgt-tools [[RichardJones|Richard W.M. Jones]] suggested[2] "we
should fold et-mgmt-tools into fedora-virt too."

==== Interface Bandwidth Controls ====
[[MaxZhen|Max Zhen]] described[1] a goal of enabling {{package|libvirt}} to configure bandwidth rate limits for the network interface of virtual machines, and asked for comments on implementation ideas.

==== RHEL 5 Support ====
[[MarkusArmbruster|Markus Armbruster]] posted[1] a
"patch series attempts to make {{package|libvirt}} just work on RHEL-5.  Right
now it doesn't, mostly because <code>libvirt</code> relies on version number checks
in a couple of places, and RHEL-5's version numbers aren't the whole
truth due to various backports of later stuff." Adding
"I'm not proposing this for immediate commit, as I'm still testing.
But I'd appreciate review: is this the right way to do it?"

Virtualization

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

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."
