[libvirt] [PATCH] Look in /usr/libexec for the qemu-kvm binary.
by Chris Lalancette
On RHEL-5 the qemu-kvm binary is located in /usr/libexec.
To reduce confusion for people trying to run upstream libvirt
on RHEL-5 machines, make the qemu driver look in /usr/libexec
for the qemu-kvm binary.
To make this work, I modified virFindFileInPath to handle an
absolute path correctly. I also ran into an issue where
NULL was sometimes being passed for the file parameter
to virFindFileInPath; it didn't crash prior to this patch
since it was building paths like /usr/bin/(null). This
is non-standard behavior, though, so I added a NULL
check at the beginning.

[libvirt] [PATCH] Clarify lack of generated IDE -device string in QEMU driver
by Matthew Booth
The QEMU driver contained code to generate a -device string for piix4-ide, but
wasn't using it. This was intentional. This change removes the string generation
and adds a comment explaining why no -device is necessary.
* src/qemu/qemu_conf.c: Remove VIR_DOMAIN_CONTROLLER_TYPE_IDE handler in
qemuBuildControllerDevStr(). Add comments.

[libvirt] vshRunConsole:77 : unable to open tty
by Ruben Kerkhof
Hi all,
I'm unable to open a serial console to a kvm virtual machine with
virsh console:
[root@phy003 ~]# virsh console f12
Connected to domain f12
Escape character is ^]
20:43:48.282: error : vshRunConsole:77 : unable to open tty /dev/pts/
1 : No such file or directory
If you look carefully to the message above, there's a space after /dev/
pts/1
I can also see this in the xml:
[root@phy003 ~]# virsh dumpxml f12 > f12.xml
<console type='pty' tty='/dev/pts/1^M'>
<source path='/dev/pts/1^M'/>
<target port='0'/>
</console>
<console type='pty' tty='/dev/pts/1^M'>
<source path='/dev/pts/1^M'/>
<target port='0'/>
</console>
I've run gdb over virsh, and this is what virDomainGetXMLDesc returns:
<console type='pty' tty='/dev/pts/1\r'>
I'm not sure if this has already been fixed, this is
libvirt-0.7.5-3.fc12.x86_64 from the rawhide preview repo on F12, with
qemu-kvm-0.12.2-4.fc12.x86_64
Any help would be appreciated.

[libvirt] [PATCH] util.c (virGetUserEnt): don't use a negative value as allocation size
by Jim Meyering
Not a big deal, but reporting a failed sysconf call will make
this far easier to diagnose than reporting an unwarranted OOM.
