=== F13 Virtualization Release Notes ===
=== Relnotes Scratchpad Pages ===
For the moment, I have [[User:Dale/Drafts/F12_Virtualization_Release_Notes| copied the F12 Virtualization Release Notes]] for use in constructing the [[Docs/Beats/Virtualization | F13 notes]].
For each release I begin by gathering all the info I can and place it on the
following pages before moving it to the public release notes beat page.

==== Bugs ====
* [[Virtualization_bugs]]
* [https://bugzilla.redhat.com/showdependencytree.cgi?id=F12VirtTarget&hide_resolved=1 F12 Virt Target]
* [https://bugzilla.redhat.com/showdependencytree.cgi?id=F12VirtBlocker&hide_resolved=1 F12 Virt Blocker]
 
==== Features ====
* [[:Category:F12_Virt_Features | F12 Virt Features List]]
 
* [[Features/VirtioSerial | VirtioSerial]] Adds a virtio-serial device to guests running on top of qemu and kvm - [[Releases/12/FeatureList | accepted ]]
* [[Features/VirtgPXE | VirtgPXE]] Replace the deprecated etherboot pxe booting infrastructure with the more modern and currently upstream supported gpxe. - [[Releases/12/FeatureList | accepted ]]
* [[Features/libguestfs | libguestfs ]] Libguestfs is a library for accessing and modifying virtual machine disk images.  guestfish is an interactive shell tool for editing virtual machine disk images. - [[Releases/12/FeatureList | accepted ]]
: Technically, this actually launched in F11, but not as a "Feature" http://docs.fedoraproject.org/release-notes/f11/en-US/sect-Release_Notes-Virtualization.html
* [[Features/SR-IOV | SR-IOV]] Single Root I/O Virtualization (SR-IOV) is a PCI feature which allows virtual functions (VF) to be created that share the resources of a physical function (PF). - [[Releases/12/FeatureList | accepted ]]
* [[Features/KVM_Huge_Page_Backed_Memory | KVM Huge Page Backed Memory]] - Enable KVM guests to use huge page backed memory in order to reduce memory consumption and improve performance by reducing CPU cache pressure. - [[Releases/12/FeatureList | accepted ]]
* [[Features/KVM qcow2 Performance | KVM qcow2 Performance]] - Improve the I/O performance of virtual machines using disk images in the qcow2 image format. - [[Releases/12/FeatureList | accepted ]]
* [[Features/Network_Interface_Management|Network Interface Management]] - Provide tools to easily set up commonly used network configurations, like bridges, bonds, vlan's and sensible combinations thereof, in particular for virtualized hosts. - [[Releases/12/FeatureList | accepted ]]
* [[Features/KSM|KSM]] - Allow KVM guest virtual machines to share identical memory pages. This is especially useful when running multiple guests from the same or similar base operating system image. Because memory is shared, the combined memory usage of the guests is reduced. - [[Releases/12/FeatureList | accepted ]]
* [[Features/KVM_NIC_Hotplug|KVM NIC Hotplug]] - Allow the addition of a guest network interface (NIC) a guest virtual machine without needing to restart the guest.  - [[Releases/12/FeatureList | accepted ]]
* [[Features/KVM_Stable_Guest_ABI|KVM Stable Guest ABI]] - Allow guest virtual machines to be presented with the same application binary interface across QEMU upgrades.  - [[Releases/12/FeatureList | accepted ]]
* [[Features/VirtPrivileges|Virt Privileges]] - Improve security by adjusting the privileges of QEMU processes managed by libvirt. Also, allow KVM to be used by unprivileged users.  - [[Releases/12/FeatureList | accepted ]]
* [[Features/VirtStorageManagement|Virt Storage Management]] - Enable VM hosts to discover new SAN storage and issue NPIV operations. - [[Releases/12/FeatureList | accepted ]]
 
Not exactly an accepted feature, but mentioned in rel notes.
* [[Features/VirtTCK|Libvirt Technology Compatibility Kit]] - Provide a functional test suite for virtualization and report on hypervisor compatability. - pending F13

=== F11 Virtualization Release Notes ===
For the moment, I have [[User:Dale/Drafts/F10_Virtualization_Release_Notes| copied the F10 Virtualization Release Notes]] for use in construction the [[Docs/Beats/Virtualization | F11 notes]].
 
Preliminary [http://poelstra.fedorapeople.org/schedules/f-11/f-11-docs-tasks.html Schedule]:
* Prepare Alpha Release Notes (1 page)  Mon 2009-02-02 Tue 2009-02-03
* Post Final Alpha Release Notes Tue 2009-02-03 Tue 2009-02-03
* Prepare Beta Release Notes (1 page)  Mon 2009-03-23  Mon 2009-03-23
* Post Beta Release Notes One-Page  Mon 2009-03-23  Mon 2009-03-23
 
==== Todo ====
* "One thing that's missing is a "new features and improvements" for KVM - both the kvm package, and the kvm support in the kernel." <ref>https://www.redhat.com/archives/fedora-virt/2009-February/msg00009.html</ref>
* Go over changelogs of pkgs and pick out notable diffs from F10 release ver to F11 ver.

Windows KVM Guest and Paravirt NIC Drivers

As seen in FWN#152. The virt-manager GUI doesn't have the knobs in the UI yet to enable virtio drivers. THe libvirt framework underneath does support it, so it can be done by hand. Here's how.

  • Download the drivers to guest and extract on desktop.
  • Shutdown the guest virsh shutdown winxp
  • Dump the libvirt XML virsh dumpxml winxp > winxp-before.xml, and change the network settings. To the <interface> block add <model type='virtio'/> like this:
[root@seitan virt]# diff -u winxp-before.xml winxp-after.xml
