Fedora Virtualization List
This section contains the discussion happening on the fedora-virt list.
Virtualization Test Day
The latest Fedora Test Day focused on Virtualization improvements in Fedora 12. Even though the test day was on Sept. 17th, you can still help make F12 the best release possible and learn about the newest features in the process. Visit the test day page, download the live image, and post your experiences on the wiki.
This section contains the discussion happening on the libvir-list.
New Release libvirt 0.7.1
"There is a fair amount of new features and improvement, not surprizing considering 0.7.0 was 1.5 months ago. And of course many bug fixes and cleanups:"

- Secret manipulation public API (Miloslav Trmač)
- support lzop save compression for qemu (Charles Duffy)
- Support new PolicyKit 1.0 API (Daniel P. Berrange)
- Compressed save image format for Qemu. (Chris Lalancette)

New Release perl-Sys-Virt 0.2.2
- Add all new APIs upto libvirt 0.7.0 APIs (listing defined network interfaces)
- Add missing APIs for looking up storage volumes based on path and key
- Fix lookup of network interfaces based on MAC address

Guest Sound Over VNC
Dave Allan noticed "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.
Daniel Berrange explained "It is complicated :-) In Fedora >= 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, 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."
