Fedora Xen List
This section contains the discussion happening on the fedora-xen list.
virt-what Script Detects Running in a Virtual Machine
Richard W.M. Jones announced[1] version 1.0 of | 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
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 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"

Testing LiveCD Distros as DomU Guests
jean-Noël Chardron posted[1] a howto for testing live cd images by booting them in a DomU with virt-install.

Libvirt List
This section contains the discussion happening on the libvir-list.
Daniel P. Berrange posted[1] a todo list for libvirt which was the product of a brainstorming session at Red Hat. Daniel offered this list as a good starting point for those wishing to assist in the development of libvirt.

Live Migration Sanity Checks
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.

sVirt: XML Representation of Security Labels
James Morris continued[1] work on the sVirt project by investigating how and when to label the resources accessed by domains and proposed an XML representation of these labels.

LXC: Making the Private Root Filesystem More Secure
After committing the private root filesystem code for LXC Daniel P. Berrange noted[1] that cgroups supports device ACLs which could defend against 'mknod' escapes into the host OS devices.

Exposing Unique Hypervisor Features
Nguyen Anh Quynh asked[1] how libvirt can expose the unique features of a given hypervisor such as the monitor interface of Qemu. 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 document.
