[libvirt] Repack git repo?
by Michal Privoznik
So I was checking out the repo the other day and it took ages. So it got
me thinking what might be the problem. Looks like a part of it is that
our pack is split among ~250 files. Therefore when somebody does
checkout git needs to repack it into a single pack every time. And this
may take ages on such slow processor as Atom is. However, reading some
docs on this it looks like 'git gc --aggressive' is not advised rather
than 'git repack'.
Any thoughts?

[libvirt] [PATCH 00/24] qemu: refactor node name detection
by Peter Krempa
Since query-blockstats provides full hierarchy of node names without any doubtful
matching algorithm, use it to make the node name detector reliable.
Unfortunately some of the changes are ugly when viewed as a diff since they
delete and rewrite chunks of code.
This series can be fetched at:

[libvirt] [PATCH v3 0/2] Allow saving VM state to pipe
by Chen Hanxiao
This series introduce flag VIR_DOMAIN_SAVE_DIRECT
to enable command 'save' to write to PIPE.
This will write QEMU_SAVE_MAGIC directly.
Base upon patches from Roy Keene <rkeene(a)knightpoint.com>
with some fixes.
Change from original patch:
1) Check whether the specified path is a PIPE.
2) Rebase on upstream.
3) Add doc for virsh command
v3:
add doc/news.xml
rebase on upstream
v2-resend:
rebase on upstream
v2:
rename VIR_DOMAIN_SAVE_PIPE to VIR_DOMAIN_SAVE_DIRECT
remove S_ISFIFO check

[libvirt] [PATCH] driver: conditionalize use of dlopen functions & use mingw-dlfcn
by Daniel P. Berrange
Not every platform is guaranteed to have dlopen/dlsym, so we should
conditionalize its use. Suprisingly it is actually present for Win32
via the mingw-dlfcn add on, but we should still conditionalize it.

[libvirt] [PATCH v3] Add support for virtio-net.tx_queue_size
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1462653
Just like I've added support for setting rx_queue_size (in
c56cdf259 and friends), qemu just gained support for setting tx
ring size.

diff to v2:
- rebase to current HEAD
There's no fundamental change since v1. It's just discussion on this patch that
makes me send newer versions because the older ones do not apply cleanly
anymore.
