[libvirt] [PATCH] docs: document <controller> element
by Eric Blake
* docs/formatdomain.html.in: Talk about <controller> and <address>
throughout.
---
Adding a new <controller type='ccid' index='0'/> and use of
<smartcard><address/></smartcard> for use by smartcard will be a lot
easier if I can compare the changes to existing <controller> and
<address> locations. To my surprise, there wasn't any documentation
for existing uses. Suggestions for polishing this are welcome, but
it's strictly an improvement over the nothingness that was there
previously ;)

[libvirt] Fwd: [PATCH] Add support for multiple serial ports to Xen driver
by Michal Novotny
Hi,
I've been posting this patch using git send-email but unfortunately it
didn't arrive to the list but I saw some other mails arrive to the list
AFAIK so I'm posting this one just to make sure it wasn't my sendmail issue.

Subject: [PATCH] Add support for multiple serial ports to Xen driver
Date: Thu, 20 Jan 2011 13:20:50 +0100
From: Michal Novotny <minovotn(a)redhat.com>
To: libvir-list(a)redhat.com
CC: Michal Novotny <minovotn(a)redhat.com>
Hi,
this is the patch for to support multiple serial ports
for Xen driver. The definition for Xen has been
introduced in BZ #614004 and this is adding
support to libvirt-based tools.
The patch was originally written for RHEL-5 and libvirt
0.8.2 (RHEL-5.6) where it has been tested using
the virsh command and correct device creation has
been confirmed in the xend.log to have the same data
for serial ports using both `xm create` and `virsh
start` commands. Also, domains with both single and
multiple serial ports has been tested to confirm
it won't introduce any regression and everything
was working fine according to my testing. This patch
is the forward-port of RHEL-5 version of the patch.

Yup, the search php was designed in php4 time frame and those global
variables are not turned off by default for security reasons
http://fr.php.net/manual/en/security.registerglobals.php
The following patch should fix those,
thanks for raising the issue,

[libvirt] virsh fails to define a domain
by Nikunj A. Dadhania
I am using the git version of libvirt. The domain file was working
previously.
[nikunj@dhruv ~]$ rpm -q qemu-kvm
qemu-kvm-0.12.3-8.fc13.x86_64
Some more debugging suggested that qemuCapsExtractDeviceStr is returning
an error. The output of the "pci-assign,?" is not returning any useful
information on my system.
[nikunj@dhruv ~]$ qemu-kvm -device "pci-assign,?"
property "pci-assign.?" not found
can't set property "?" to "on" for "pci-assign"
[nikunj@dhruv ~]$
This is supposedly related to f892f5a562cbb6e5b914adced1000df20c3174d6
commit. Don't know what could be a valid fix for this tough.

[libvirt] [PATCH] qemu: Avoid sending STOPPED event twice
by Jiri Denemark
In some circumstances, libvirtd would issue two STOPPED events after it
stopped a domain. This was because an EOF event can arrive after a qemu
process is killed but before qemuMonitorClose() is called.
qemuHandleMonitorEOF() should ignore EOF when the domain is not running.
I wasn't able to reproduce this bug directly, only after adding an
artificial sleep() into qemudShutdownVMDaemon().
