Subject: [PATCH] virsh: Fix regression of vol-resize
Introduced by commit 1daa4ba33acf. vshCommandOptStringReq returns
0 on *success* or the option is not required && not present, both
are right result. Error out when returning 0 is not correct.
the caller, it doesn't have to check wether it
(cherry picked from commit 2a3a725c33aba2046443d33eb473eb54517f61c8)

Subject: [PATCH] Don't pass virConnectPtr in nwfilter 'struct
domUpdateCBStruct'
The nwfilter driver only needs a reference to its private
state object, not a full virConnectPtr. Update the domUpdateCBStruct
struct to have a 'void *opaque' field instead of a virConnectPtr.

Subject: [PATCH] Remove use of virConnectPtr from all remaining nwfilter code
The virConnectPtr is passed around loads of nwfilter code in
order to provide it as a parameter to the callback registered
by the virt drivers. None of the virt drivers use this param
though, so it serves no purpose.
Avoiding the need to pass a virConnectPtr means that the
nwfilterStateReload method no longer needs to open a bogus
QEMU driver connection. This addresses a race condition that
can lead to a crash on startup.
The nwfilter driver starts before the QEMU driver and registers
some callbacks with DBus to detect firewalld reload. If the
firewalld reload happens while the QEMU driver is still starting
up though, the nwfilterStateReload method will open a connection
to the partially initialized QEMU driver and cause a crash.

From d78741e154c932ba45fc31d6a2ae615f2f1d1e15 Mon Sep 17 00:00:00 2001
From: Michal Privoznik <mprivozn@redhat.com>
Date: Tue, 1 Oct 2013 15:04:48 +0200
Subject: [PATCH] qemu_hotplug: Allow QoS update in qemuDomainChangeNet
The qemuDomainChangeNet() is called when 'virsh update-device' is
invoked on a NIC. Currently, we fail to update the QoS even though
we have routines for that.
Signed-off-by: Michal Privoznik <mprivozn@redhat.com>

Subject: [PATCH] virNetDevBandwidthEqual: Make it more robust
So far the virNetDevBandwidthEqual() expected both ->in and ->out items
to be allocated for both @a and @b compared. This is not necessary true
for all our code. For instance, running 'update-device' twice over a NIC
with the very same XML results in SIGSEGV-ing in this function.
