=== Enterprise Management Tools List ===
 
This section contains the discussion happening on the
 
[http://www.redhat.com/mailman/listinfo/et-mgmt-tools et-mgmt-tools list]
 
 
==== More Device Support in virt-manager 'Add Hardware' Wizard ====
 
[[ColeRobinson|Cole Robinson]]
 
patched<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-July/msg00013.html</ref>
 
{{package|virt-manager}} to implement adding of virtual video devices in the
 
'Add Hardware' wizard.  Cole also implemented<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-July/msg00012.html</ref> attaching serial and parallel devices.
 
 
Both these features were added to
 
{{package|python-virtinst|virt-install}}<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-July/msg00010.html</ref>. Serial ports can be directed to sockets listening on remote hosts. For example: <code>--serial udp,host=192.168.10.20:4444</code>. That may come in handy for the F12 Hostinfo feature<ref>http://fedoraproject.org/wiki/Features/Hostinfo</ref>.

==== Xen, Windows, and ACPI ====
 
[[GuidoGünther|Guido Günther]]
 
noted<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-July/msg00000.html</ref>
 
that <code>virt-install</code> disables ACPI and APIC for Windows XP guests.
 
Adding, that it seems "that Windows XP is working fine with acpi/apic enabled which has
 
the immediate advantage that poweroff via ACPI works as expected.
 
So does it make sense to handle winxp the same win2k3?". Windows 2003 guests have ACPI enabled.
 
 
[[PasiKärkkäinen|Pasi Kärkkäinen]]
 
went to the xen-devel list and confirmed<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-July/msg00007.html</ref>
 
and relayed "Keir Fraser replied that ACPI with Windows has been working properly at least since Xen 3.1.0 days".
 
Pasi then updated the Xen wiki page<ref>http://wiki.xensource.com/xenwiki/XenWindowsACPI</ref>.

Unfortunately, those wishing to manage their iPhone in a guest (yours truly
 
included), KVM does not yet support the required USB 2.

==== 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 {{package|kernel}} and {{package|kernel-xen}} packages for a time. As of
 
[[Releases/9|Fedora 9]]<ref>http://docs.fedoraproject.org/release-notes/f9/en_US/sn-Virtualization.html</ref> this practice was deamed<ref>https://www.redhat.com/archives/fedora-xen/2007-November/msg00106.html</ref> untenable, and support for hosting Xen guests was dropped from Fedora.
 
 
 
Work has since focused on creating a paravirt operations dom0<ref>http://fedoraproject.org/wiki/Features/XenPvopsDom0</ref> 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<ref>http://fedoraproject.org/wiki/FWN/Issue170#Experimental_Dom0_Kernel_Update</ref> have been created for the adventurous.
 
 
 
[[PasiKärkkäinen|Pasi Kärkkäinen]]
 
tells<ref>http://www.redhat.com/archives/fedora-xen/2009-July/msg00000.html</ref> 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

and here<ref>http://x17.eu/xen/</ref>.
 
 
 
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)."

Virtualization

In this section, we cover discussion of Fedora virtualization technologies on the @fedora-virt list.

Contributing Writer: Dale Bewley

Fedora Virtualization List

This section contains the discussion happening on the fedora-virt list.

Virt Status Report

Justin Forbes posted[1] a Fedora virtualization status report. Justin pointed out F13 bugs[2] 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[1] of Red Hat Enterprise Linux 5.4 compared to Fedora 12.

Daniel Berrange explained[2] "The KVM based virtualization in RHEL-5.4 is not nearly so far behind Fedora as you might think. The Package-x-generic-16.pnglibvirt mgmt stack in RHEL-5.4 was rebased to be near parity with 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."
