Virtualization
In this section, we cover discussion of Fedora virtualization technologies on the @et-mgmnt-tools-list, @fedora-xen-list, @libvirt-list and @ovirt-devel-list lists.
Contributing Writer: Dale Bewley
Enterprise Management Tools List
This section contains the discussion happening on the et-mgmt-tools list
Fedora Virtualization List
This section contains the discussion happening on the fedora-virt list.
New Mailing List and New Releases of libguestfs
Richard Jones
announced[1]
the creation of a new list[2] dedicated to
"
/libguestfs
guestfish
/virt-inspector
discussion/development".
The current release is now 1.0.57[3], but Richard is so fast that may change by the time you read this.
Recent new features:
virt-df
- like 'df' for virtual machines- New Perl library called Sys::Guestfs::Lib
- Now available for EPEL
- Tab completion in guestfish now completes files and devices
- Big change to the code generator
- Lots more regression tests
- guestfish commands: time, glob, more, less
- new commands: readdir, mknod*, umask, du, df*, head*, tail*, wc*, mkdtemp, scrub, sh, sh-lines.
- Debian native[4] (debootstrap, debirf) support
See previous release announcement for 1.0.14 in FWN#179[5] and be sure to see the project homepage[6] for extensive usage examples.

Fedora Virt Status Update
Mark McLoughlin posted[1] another Fedora Virt Status Update reminding that Fedora 12 is quickly approaching with the Feature Freeze on 2009-07-28.
Also mentioned were:
- Details of a fix for "a dramatic slowdown in virtio-blk performance in F-11 guests"[2]
- Note on Xen Dom0 support.
- New wiki pages created.
- Detailed run-down of current virt bugs.
USB Passthrough to Virtual Machines
Mark McLoughlin
posted instructions[1] for attaching a USB device to a guest using
in Fedora 11. This was could previously (FWN#165[2]) be accomplished only on the command line by hand.
virt-manager
Unfortunately, those wishing to manage their iPhone in a guest (yours truly included), KVM does not yet support the required USB 2.
Libvirt List
This section contains the discussion happening on the libvir-list.
Fedora-Xen List
This section contains the discussion happening on the fedora-xen list.
Xen dom0 Forward Ported to Latest Kernel
Previously, Xen dom0 support in Fedora was provided by forward porting the Xensource patches from kernel 2.6.18 to the version found in the Fedora release at the time. This consumed developer resources and led to separate
and kernel
packages for a time. As of
Fedora 9[1] this practice was deamed[2] untenable, and support for hosting Xen guests was dropped from Fedora.
kernel-xen
Work has since focused on creating a paravirt operations dom0[3] kernel based on the most recent upstream vanilla kernel. This work is incomplete and not expected to be done before F12 or even F13. However, experimental dom0 kernels[4] have been created for the adventurous.
Pasi Kärkkäinen tells[5] us the Xen 2.6.18 patches have now been forward-ported to the current 2.6.29 and 2.6.30 kernel. "Forward-porting has been done by Novell for OpenSUSE. Novell also has a forward-port to 2.6.27 for SLES11."
The patches can be found here[6] here [7] and here[8].
Pasi added "These patches are still more stable and mature than the pv_ops dom0 code.. Also, these patches have the full Xen feature set (pv_ops still lacks some features)."
More history is avilable[9].
