Subject: [PATCH] qemu_command: Split qemuBuildCpuArgStr
Move the CPU mode/model handling to its own function. This is just
code movement and re-indentation.

Subject: [PATCH] PowerPC : Add support for launching VM in 'compat' mode.
PowerISA allows processors to run VMs in binary compatibility ("compat")
mode supporting an older version of ISA. QEMU has recently added support to
explicitly denote a VM running in compatibility mode through commit 6d9412ea
& 8dfa3a5e85. Now, a "compat" mode VM can be run by invoking this qemu
commandline on a POWER8 host: -cpu host,compat=power7.
This patch allows libvirt to exploit cpu mode 'host-model' to describe this
new mode for PowerKVM guests. For example, when a user wants to request a
power7 vm to run in compatibility mode on a Power8 host, this can be
described in XML as follows :
<cpu mode='host-model'>
<model>power7</model>
</cpu>

From bbdbfbfc03494f5cbba4ee869149cca37c1fd53c Mon Sep 17 00:00:00 2001
From: Cole Robinson <crobinso@redhat.com>
Date: Tue, 23 Sep 2014 13:07:09 -0400
Subject: [PATCH] qemu: Don't compare CPU against host for TCG
Right now when building the qemu command line, we try to do various
unconditional validations of the guest CPU against the host CPU. However
this checks are overly applied. The only time we should use the checks
are:
- The user requests host-model/host-passthrough, or
- When KVM is requsted. CPU features requested in TCG mode are always
emulated by qemu and are independent of the host CPU, so no host CPU
checks should be performed.
Right now if trying to specify a CPU for arm on an x86 host, it attempts
to do non-sensical validation and falls over.
Switch all the test cases that were intending to test CPU validation to
use KVM, so they continue to test the intended code.
Amend some aarch64 XML tests with a CPU model, to ensure things work
correctly.
(cherry picked from commit cf7fce8f2fd1c930f357fd4ff93ac35f38eb30c6)

Subject: [PATCH] PowerPC:Improve PVR handling to fall back to cpu generation.
IBM Power processors differ uniquely across generations (such as power6,
power7, power8). Each generation signifies a new PowerISA version
that exhibits features unique to that generation.
The higher 16 bits of PVR for IBM Power processors encode the CPU
generation, while the CPU chip (sub)version is encoded in lower 16 bits.
For all practical purposes of launching a VM, we care about the
generation which the vCPU will belong to, and not specifically the chip
version. This patch updates the libvirt PVR check to reflect this
relationship. It allows libvirt to select the right CPU generation
in case the exact match for a a specific CPU is not found.
Hence, there will no longer be a need to add each PowerPC CPU model to
cpu_map.xml; just adding entry for the matching ISA generation will
suffice.
It also contains changes to cpu_map.xml since processor generations
as understood by QEMU compat mode go as "power6", "power7" or "power8"

Subject: [PATCH] security_selinux: Don't relabel /dev/net/tun
https://bugzilla.redhat.com/show_bug.cgi?id=1147057
The code for relabelling the TAP FD is there due to a race. When
libvirt creates a /dev/tapN device it's labeled as
'system_u:object_r:device_t:s0' by default. Later, when
udev/systemd reacts to this device, it's relabelled to the
expected label 'system_u:object_r:tun_tap_device_t:s0'. Hence, we
have a code that relabels the device, to cut the race down. For
more info see ae368ebfcc4.
But the problem is, the relabel function is called on all TUN/TAP
devices. Yes, on /dev/net/tun too. This is however a special kind
of device - other processes uses it too. We shouldn't touch it's
label then.
Ideally, there would an API in SELinux that would label just the
passed FD and not the underlying path. That way, we wouldn't need
to care as we would be not labeling /dev/net/tun but the FD
passed to the domain. Unfortunately, there's no such API so we
have to workaround until then.

Subject: [PATCH] util: Prepare URI formatting for libxml2 >= 2.9.2
Since commit 8eb55d782a2b9afacc7938694891cc6fad7b42a5 libxml2 removes
two slashes from the URI when there is no server part. This is fixed
with beb7281055dbf0ed4d041022a67c6c5cfd126f25, but only if the calling
application calls xmlSaveUri() on URI that xmlURIParse() parsed. And
that is not the case in virURIFormat(). virURIFormat() accepts
virURIPtr that can be created without parsing it and we do that when we
format network storage paths for gluster for example. Even though
virStorageSourceParseBackingURI() uses virURIParse(), it throws that data
structure right away.
Since we want to format URIs as URIs and not absolute URIs or opaque
URIs (see RFC 3986), we can specify that with a special hack thanks to
commit beb7281055dbf0ed4d041022a67c6c5cfd126f25, by setting port to -1.
This fixes qemuxml2argvtest test where the disk-drive-network-gluster
case was failing.
