| ==== '''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"

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

| This section contains the discussion happening on the [https://www.redhat.com/mailman/listinfo/libvir-list libvir-list].
| |
| | |
| [[DanielBerrange|Daniel P. Berrange]] posted[1] a [http://wiki.libvirt.org/page/Todo 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 ====
| | 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.

| ==== sVirt: XML Representation of Security Labels ==== | | ==== Virt Status Report ==== |
| [[JamesMorris|James Morris]] continued[1] work on the [http://selinuxproject.org/page/SVirt sVirt] project by investigating how and when to label the resources accessed by domains and proposed an XML representation of these labels. | | [[JustinForbes|Justin Forbes]] |
| | posted<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00056.html</ref> a Fedora virtualization status report. |
| | 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. |

| ==== LXC: Making the Private Root Filesystem More Secure ==== | | ==== RHEL and Fedora Virtualization Feature Parity ==== |
| After committing the private root filesystem code for LXC [[DanielBerrange|Daniel P. Berrange]] noted[1] that [http://libcg.sourceforge.net cgroups] supports device ACLs which could defend against 'mknod' escapes into the host OS devices.
| | Robert Day wondered how the virtualization features<ref>http://www.redhat.com/virtualization/rhev/</ref> of Red Hat Enterprise Linux 5.4 |
| | compared to Fedora 12. |
|
| |
|
| [1] https://www.redhat.com/archives/libvir-list/2008-August/msg00734.html | | [[DanielBerrange|Daniel Berrange]] |
| | explained<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00040.html</ref> |
| | "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].
