[libvirt] [PATCH] storage: show compile options in virsh --version=long
by Eric Blake
Adding output to 'virsh --version=long' makes it easier to
tell if a distro built with particular libraries (it doesn't
tell you what a remote libvirtd is built with, but is still
better than nothing).
* tools/virsh.c (vshShowVersion): Add gluster witness.

[libvirt] Glusterfs Libvirt issue
by Umar Draz
Hi,
I am trying to create glusterfs pool with libvirt but its working, and
following is the error
*libvirt_storagepool_define_xml(): internal error unknown storage pool type
gluster*
the Qemu has enabled glusterfs backend support. I can create the glusterfs
image using this
*qemu-img create gluster://localhost/test/umar 5G*
Would you please help what should else i need to require?

[libvirt] [PATCH python 00/14] Finished port to Python3
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
This series finishes the initial port to Python3. The code
generator works, the C code compiles without warnings, and
the sanitytest passes.
The APIs using strings have all switched to PyUnicode
except for thos which deal with binary data which now use
PyBytes in Python 3 builds.
Daniel P. Berrange (14):
examples: Invoke print("...") instead of print "..."
examples: Ensure we write bytes to the self-pipe
override: Fix native module registration to work with Python3
sanitytest: Fix libvirtError class handling for Python 2.4
override: Replace PyString_FromString with libvirt_constcharPtrWrap
override: Replace PyString_AsString with libvirt_charPtrUnwrap
override: Replace Py{Int,Long}_FromLong with helpers
override: Replace PyInt_AsLong with helper
typewrappers: Replace use of PyString class
typewrappers: PyInt/PyLong merge for Python3
override: Conditionalize use of PyString_Check and PyInt_Check
override: Switch virStreamSend wrapper to use
libvirt_charPtrSizeUnwrap
sanitytest: Fix broken comparison between int and string
sanitytest: remove use of string.lower()

This will make configurations that could be running for years (except
that the guest OS was ignoring the NUMA data) suddenly stop running. I
just want to confirm: we really want that, right?
Does libvirt allow this kind of broken configuration to be generated, or
it already ensures the total NUMA node sizes match RAM size?

[libvirt] [PATCH 0/6] Some virtlockd improvements
by Michael Chapman
Hi,
This patch series fixes up a few problems encountered while testing out
virtlockd.
The biggest problem was that reloading virtlockd through systemd or its
initscript would send it a SIGHUP, not a SIGUSR1 (which causes it to re-exec
itself). This would simply kill it. Patches 1-3 clean this up by having SIGHUP
behave the same as SIGUSR1. The systemd unit and initscript have to use
SIGUSR1, though, since they may be called upon to signal an old virtlockd
binary.
When run from the initscript graceful re-exec didn't work properly anyway, as
virtlockd assumed argv[0] was a full path to its binary. The initscript didn't
provide a full path. Patches 4-5 make virtlockd use execvp() to re-exec itself,
which does a PATH lookup if necessary.
Patch 6 isn't really virtlockd-specific. It moves the reloading of virtlockd
and libvirtd via initscripts into the libvirt-daemon package's %postun
scriptlet (which is already where reloading is done with systemd). The problem
with reloading libvirt-daemon in %post is that it restarts *before* all of the
libvirt-daemon-driver-* packages have been updated in the same RPM transaction,
which means it keeps using the old libraries (or fails to load them due to
missing symbols).
Michael Chapman (6):
virtlockd: improve systemd units
virtlockd: improve initscripts
virtlockd: treat SIGHUP like SIGUSR1
virtlockd: use common exit path when out-of-memory
virtlockd: make re-exec more robust
spec: clean up libvirtd and virtlockd service mgmt

[libvirt] [PATCH 0/9] Add throttle blkio cgroup support for libvirt
by Gao feng
Right now, libvirt only supports the cfq based blkio cgorup,
this means if the block devices doesn't use cfq scheduler, the
blkio cgroup will loss effect.
This patchset adds the throttle blkio cgroup support for libvirt,
intoduces four elements for domain configuration and extend the
virsh command blkiotune.
This patchset is a new version of Guan Qiang's patchset
://www.redhat.com/archives/libvir-list/2013-October/msg01066.html
Change form Guan Qiang's patchset:
1, split to 8 patches, make logic more clear
2, change the type of read/write iops form unsigned long long to unsigned int,
trying to set read/write iops to the value which bigger than max number of
unsigned int will fail.
3, fix some logic shortage.
Gao feng (9):
rename virDomainBlkioDeviceWeightParseXML to
virDomainBlkioDeviceParseXML
rename virBlkioDeviceWeightArrayClear to virBlkioDeviceArrayClear
rename virBlkioDeviceWeightPtr to virBlkioDevicePtr
domain: introduce xml elements for throttle blkio cgroup
blkio: Setting throttle blkio cgroup for domain
qemu: allow to setup throttle blkio cgroup through virsh
virsh: add virsh manual for setting throttle blkio cgroup
lxc: allow to setup throttle blkio cgroup through virsh
qemu: add new throttle blkio cgroup elements to the test xml
