| === Fedora Xen List ===
| |
| This section contains the discussion happening on the [https://www.redhat.com/mailman/listinfo/fedora-xen fedora-xen list].
| |
| | |
| ==== Laying the Groundwork for Xen Domain 0 Support ====
| |
| There are further developments in the state of Xen in upstream Linux (see FWN#137[3]). Pasi Kärkkäinen forwarded[1] a patch announcement[2] from xen-devel list. This set of seven patches begin to lay the groundwork for Xen domain 0 support.

| |
| | |
| [[DanielBerrange|Daniel P. Berrange]] said[4] these patches will make their way into [[Releases/Rawhide | rawhide]] when they are merged into the LKML[5] dev tree line used by rawhide at that time.

| === Libvirt List ===
| |
| This section contains the discussion happening on the [https://www.redhat.com/mailman/listinfo/libvir-list libvir-list].
| |
| | |
| ==== Libvirt 0.4.5 Released ====
| |
| [[DanielVeillard|Daniel Veillard]] announced[1] the release of libvirt 0.4.5. In addition to a long changelog, the "main features are the improvement of OpenVZ and LXC, the uniform XML handling (and hence format) th[r]ough all drivers, improvements in devices handling for QEmu/KVM and storage pool source discovery."

| |
| | |
| ==== Segfault if no Qemu Emulator Passed ====
| |
| [[ColeRobinson|Cole Robinson]] patched[1] a bug that resulted in a segfault if
| |
| a Qemu domain is defined without an emulator value. [[DanielBerrange|Daniel Berrange]] expressed[2] displeasure at letting this bug slip through and proposed a "brown paper bag" release. [[DanielVeillard|Daniel Veillard]] advised[3] against rushing the fix, and offered to push the patch to Fedora's build while other distributions could pick up the fix in a week or two when libvirt 0.4.6 would presumably be released.

| |
| | |
| Daniel Berrange pointed out code test coverage reports[4] on the build server, and highlighted the need to create a functional test rig for the mass of code that is simply not possible to unit test due to interactions with host OS state / functionality.

| | |
| ==== Ability to Nice KVM Processes ====
| |
| [[HenriCook|Henri Cook]] expressed[1] a desire to nice KVM processes, and proposed a means to pass arbitrary command string parameters to the process startup.
| |
| | |
| As mentioned[2] in FWN #141, [[DanielBerrange|Daniel Berrange]] pointed out[3] the goal of libvirt is consistent API representation across hypervisors. Fortunately there is a 'schedular parameters' API in libvirt. All that's needed is for someone to implement the schedular parameters driver API for KVM.

| |
| | |
| ==== RFC Thoughts on Open Source Hypervisor Management ====
| |
| [[NathanCharles|Nathan Charles]] described[1] his ideal clustered VM provisioning system. Features would include
| |
| * cluster administration is done from the command line
| |
| * cluster administration can be performed from any node
| |
| * a new node can join a cluster on a local subnet with one command
| |
| * local storage resources are presented to the cluster so there is no need to have predefined NAS/SAN/iSCSI
| |
| * cluster will load balance vm instances from node to node
| |
| * a node shouldn't need more than one nic but adding additional nic's provides failover and load balancing
| |
| Nathan acknowledged oVirt's virtues, but stated it requires a lot of substantial changes and significant modification to work with an existing provisioning infrastructure. Nathan requested comments on his thoughts.

| |
| | |
| The only reply[2] so far came from [[StefanKonink|Stefan de Konink]], who pointed to some code[3] which seems[4] to be a "handler for libvirt using avahiclient".

| === oVirt Devel List ===
| |
| This section contains the discussion happening on the [https://www.redhat.com/mailman/listinfo/ovirt-devel ovirt-devel list].
| |
| | |
| ==== oVirt Migration Status ====
| |
| [[AtsushiSAKAI|Atsushi SAKAI]] asked[1] if the following assumptions were
| |
| true. KVM supports migration, while Qemu does not. Ovirt release supports migration, developer version does not. [[ChrisLalancette|Chris Lalancette]] clarified[2] "there is live migration code in upstream kvm userspace, but not in upstream qemu" and fully emulated guests can be live migrated as long as the KVM binary is used to do it (which ovirt does).

| |
| | |
| [2] https://www.redhat.com/archives/ovirt-devel/2008-September/msg00108.html
| |
| | |
| Atsushi inquired of the fake managed nodes, and Chris Lalancette explained[3] the fake managed nodes are abstractions to allow experimenting oVirt with limited hardware. [[PerryMyers|Perry N. Myers]] added[4] there is work underway to remove the 'fake node' concept.

| | [[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. |

| | ==== RHEL and Fedora Virtualization Feature Parity ==== |
| | 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. |
|
| |
|
| === Other Virtualization News ===
| | [[DanielBerrange|Daniel Berrange]] |
| This section contains virtualization news which may not have been directly discussed on the above mailing lists.
| | 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." |

| ==== Red Hat Acquires Makers of KVM, Qumranet Inc. ====
| | <references /> |
| On September 4, 2008 Red Hat acquired[1][2] Qumranet, Inc., the inventor and key maintainer of KVM. Qumranet also develops Solid ICE[3] which runs a user's desktop in a KVM virtual machine in the data center with users connecting via thin client or other options.
