[libvirt] [PATCH v3 0/6] Support keyboard device
by Li Zhang
From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com>
This patchset is to add keyboard input device.
For PPC64, it doesn't support a default keyboard device when the graphic
is enabled. Libvirt supports QEMU command line as "-device VGA" which
won't create any keyboard device for it. So it requires libvirt to add
a default USB keyboard device for it.
This patchset is to add keyboard input device and a default USB keyboard
for PPC64.
The related discussion in QEMU community:
http://lists.nongnu.org/archive/html/qemu-devel/2013-11/msg01734.html
Li Zhang (6):
conf: Add a keyboard input device type
conf: Add one interface to add input devices.
Remove PS2 mouse device for non-X86 platforms
qemu_cap: Add USB keyboard capability
qemu: parse qemu command line for USB keyboard.
Add a default USB keyboard for PPC64
v3 -> v2:
* Handle the KBD device type in xen and QEMU driver. (Daniel.P.Berrange)
* Remove PS2 mouse device for non-X86 platforms.
* Move virDomainDefMaybeAddInput to a new patch. (Jan Tomko)
* Replace VIR_REALLOC_N with VIR_APPEND_ELEMENT. (Jan Tomoko)
* Fix several typos. (Jan Tomoko)
* Add a virReportError when QEMU_CAPS_DEVICE_USB_KBD can't be gotten. (Jan Tomoko)
v2 -> v1:
* change ifs to switch clause.
* reconstruct the patches

[libvirt] [PATCH] storage: fix omitted slash in gluster volume URI
by Eric Blake
When doing 'virsh vol-dumpxml' on a gluster pool's volume, the
resulting URI incorrectly omitted a slash between hostname and
path: gluster://192.168.122.206rhsvol1/fedora-19.img
This is fallout from me rebasing earlier versions of my patch,
I had originally played with always requiring the gluster volume
to have a leading slash, but it was easier to use the gluster
API if the gluster volume name was guaranteed to have no slash;
while I got the URI of the pool correct, I forgot to fix the URI
of a libvirt volume.
* src/storage/storage_backend_gluster.c
(virStorageBackendGlusterRefreshVol): Use correct starting point
since uri construction requires leading slash.

Once approved, I'm also pushing to v1.2.0-maint

[libvirt] [PATCH] Revert "virtlockd: treat SIGHUP like SIGUSR1"
by Michal Privoznik
This reverts commit 8355d42dd3df514c8584e0e5082b945b79671fc5.
After some discussion upstream [1] this patch turns out to be spurious.
It better gets reverted prior to a release.

[libvirt] Timing proposal for the next couple of releases
by Daniel Veillard
In general December is a month with low productivity, especially over
the end of the month, as a result doing a freeze at that time may not
be very efficient. Also I will be rather busy around end of January
with travels and FOSDEM it's also the chinese new year, then February
is a short month.
My suggestion would be to rather plan 2 releases in 3 months, i.e.
one around the 15th January with a freeze around Jan 8th, and then a
release at the end of February with a freeze around 21st Feb. After that
we are back to monthly end of month usual schedule.
Does that sounds okay with everybody ?
Daniel

[libvirt] [PATCH] qemu_process: Read errors from child
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1035955
There's a window when starting a qemu process between fork() and exec()
during which we are doing things that may fail but not tunnelling the
error to the daemon. This is basically all within qemuProcessHook().
So whenever we fail in something, e.g. placing a process onto numa node,
users ale left with:
error: Child quit during startup handshake: Input/output error
while the original error is thrown into the domain log:
libvirt: error : internal error: NUMA memory tuning in 'preferred'
mode only supports single node
Hence, we should read the log file and search for the error message and
report it to users.

[libvirt] [libvirt-glib 0/4] Add symbol files checks to make check

Hey,
This series is based of the libosinfo work danpb did recently to reuse
libvirt scripts to validate the symbol files. These make sure the exported
symbols match what is listed in the sym file, and that these files are alphabetically
ordered. This caught 2 minor errors in the sym files we currently ship.
