F12 Virtualization Release Notes

For the moment, I have copied the F11 Virtualization Release Notes for use in constructing the F12 notes.



  • VirtioSerial Adds a virtio-serial device to guests running on top of qemu and kvm - accepted
  • Hostinfo Allow a virtual machine to see information and statistics from the host operating system - pending
  • VirtgPXE Replace the deprecated etherboot pxe booting infrastructure with the more modern and currently upstream supported gpxe. - accepted
  • 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. - accepted
Technically, this actually launched in F11, but not as a "Feature"
  • 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). - accepted
  • 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. - accepted
  • KVM qcow2 Performance - Improve the I/O performance of virtual machines using disk images in the qcow2 image format. - accepted
  • 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. - accepted
  • 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. - accepted
  • KVM NIC Hotplug - Allow the addition of a guest network interface (NIC) a guest virtual machine without needing to restart the guest. - accepted
  • KVM Stable Guest ABI - Allow guest virtual machines to be presented with the same application binary interface across QEMU upgrades. - accepted
  • Virt Privileges - Improve security by adjusting the privileges of QEMU processes managed by libvirt. Also, allow KVM to be used by unprivileged users. - accepted
  • Virt Storage Management - Enable VM hosts to discover new SAN storage and issue NPIV operations. - accepted

Not exactly an accepted feature, but mentioned in rel notes.

Windows KVM Guest and Paravirt NIC Drivers

As seen in FWN#152. The Package-x-generic-16.pngvirt-manager GUI doesn't have the knobs in the UI yet to enable virtio drivers. THe Package-x-generic-16.pnglibvirt 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 
--- winxp-before.xml	2008-12-01 17:37:39.000000000 -0800
+++ winxp-after.xml	2008-12-01 17:39:21.000000000 -0800
@@ -26,6 +26,7 @@
     <interface type='network'>
+      <model type='virtio'/>
       <mac address='54:52:00:03:09:01'/>
       <source network='default'/>
       <target dev='vnet0'/>
  • Redefine the domain with the altered config: virsh define winxp-after.xml
  • Start the guest virsh start winxp, and install the drivers within Windows when the new hardware detection wizard pops up.
