==== Guest Sound Over VNC ====
[[DaveAllan|Dave Allan]]
noticed<ref>http://www.redhat.com/archives/libvir-list/2009-September/msg00494.html</ref>
"when a KVM guest created with virt-manager is running on F10, sound on the
physical host stops working. When all VMs are shutdown, sound starts working
again. Removing the <sound> tag from the VM XML allows sound to work while the
VM is booted." and suggested disabling sound in guests by default.
[[DanielBerrange|Daniel Berrange]]
explained<ref>http://www.redhat.com/archives/libvir-list/2009-September/msg00499.html</ref>
"It is complicated :-)  In Fedora &gt;= 11 we currently disable all use of
sound cards, but this upsets people who want sound ;-P  I'm working
on a new version of the patch which sets up audio-over-VNC<ref>http://fedoraproject.org/wiki/Features/VirtVNCResourceTunnel</ref>, while for
SDL allows the host audio backend to be used & configured.
I still need to finish my GTK-VNC patches to do the client end of
audio over VNC, then it'll all play correctly with desktop audio
services via gstreamer/pulseaudio."

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."
