[libvirt] [PATCH] hooks: Fix a wrong description
by Chen Hanxiao
From: Chen Hanxiao <chenhanxiao(a)gmail.com>
In the definition of virHookQemuOpType and virHookNetworkOpType,
we should use 'stopped' rather than 'shutdown'.

[libvirt] [PATCH] qemuBuildDriveDevStr: Prefer default aliases for IDE bus
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1434451
When testing user aliases it was discovered that for 440fx
machine type which has default IDE bus builtin, domain cannot
start if IDE controller has the user provided alias. This is
because for 440fx we don't put the IDE controller onto the
command line (since it is builtin) and therefore any device that
is plugged onto the bus must use the default alias.

[libvirt] [PATCH] vircapstest: Avoid (im)possible strcmp call with NULL argument
by Jiri Denemark
Some compiler may get confused and decide we are calling strcmp with
NULL argument from test_virCapsDomainDataLookupLXC. Although this does
not really happen since the call is guarded with
(data->machinetype != expect_machinetype), using STRNEQ_NULLABLE is
easier to understand, less fragile, and doing so makes sure strcmp is
never called with NULL argument.

[libvirt] [PATCH] virhostcpu: Report correct topolgy info on host with deconfigured core
by Nitesh Konkar
The host which has a deconfigured core is treated as though the topology is
not correct and the SMT is not reliable. Which is not true, so report the topology
correctly by detecting if the host is actually in a proper SMT mode with
the deconfigured core.
Signed-off-by: Nitesh Konkar <nitkon12(a)linux.vnet.ibm.com>
---
Steps to reproduce:
This is what `virsh capabilities` shows in a
10-core POWER8 system (8 threads per core):
$ virsh capabilities | grep threads
<topology sockets='1' cores='10' threads='8'/>
There are 10 CPUs online, given SMT is off (`ppc64_cpu --smt=off`):
$ cat /sys/devices/system/cpu/online
0,8,16,24,32,40,48,56,64,72
Now, if one core is disabled/offlined (e.g., the last one, number 72)...
$ echo 0 | sudo tee /sys/devices/system/cpu/cpu72/online
Then this messes up with `virsh capabilities` number of cores (now 80) and threads (now 1) :
$ virsh capabilities | grep threads
<topology sockets='1' cores='80' threads='1'/>
It goes back to normal if that CPU is enabled/onlined again:
$ echo 1 | sudo tee /sys/devices/system/cpu/cpu72/online
1
$ virsh capabilities | grep threads
<topology sockets='1' cores='10' threads='8'/>
