Commit dc33e6e4 caused older platforms like Fedora 20 to emit
scary log messages at startup:

2014-11-19 23:12:58.800+0000: 28906: error : virCommandWait:2532 : internal error: Child process (/usr/sbin/iptables -w -L -n) unexpected exit status 2: iptables v1.4.19.1: unknown option "-w"

Since we are probing and expect to handle the case where -w is not
supported, we should not let virCommand log it as an error.

When a block{pull, copy, commit} is aborted via keyboard interrupt,
the job is properly canceled followed by proper error message.
However, when the job receives an abort from another client connected
to the same domain, the error message incorrectly indicates that
a blockjob has been finished successfully, though the abort request
took effect. This patch introduces a new blockjob abort handler, which
is registered when the client calls block{copy,commit,pull} routine,
providing its caller the status of the finished blockjob.

Any attempt to start a tunnelled migration with libvirtd that supports
RDMA migration (specifically commit v1.2.8-226-ged22a474) crashes
libvirtd on the destination host.

The crash is inevitable because qemuMigrationPrepareAny is always called
with NULL protocol in case of tunnelled migration.

As discussed on the upstream list, it's better not to make this
kind of predictions in libvirt. It may happen that qemu learns
how to enable OVMF on other architectures too and we shouldn't
try to chase that.

Currently, we are whitelisting architectures, that we know how to run
OVMF on. So far, only x86_64 was enabled. However, looking at qemu
code, the same commandline can be used to enable OVMF for armv7l and
aarch64.

I noticed this while working on qemuDomainGetBlockInfo.  Assigning
a bool value to an int variable compiles fine, but raises red flags
on the maintenance front as it becomes too easy to assign -1 or 2
or any other non-bool value to the same variable.

Use of an 'int' to represent a 'bool' value is confusing.  Just
because dbus made the mistake of cementing their 4-byte wire
format of dbus_bool_t into their API doesn't mean we have to
repeat the mistake.  With a little bit of finesse, we can
guarantee that we provide a large-enough value to the DBus
code, while still copying only the relevant one-byte bool
to the client code, and isolate the rest of our code base from
the DBus stupidity.

This function returned non-inactive domains instead of active
domains.  This broke virConnectNumOfDefinedDomains() and
virConnectListDefinedDomains() functions.

Ethernet interfaces in libvirt currently do not support bandwidth setting.
For example, following xml file for an interface will not apply these
settings to corresponding qdiscs.

Since 1.2.8 it's possible to use OVMF on domains. Moreover, it's
possible to have libvirt create NVRAM file per domain. Later,
when domain is undefined, the file is removed too. However,
things are a bit complicated when domain's transient. There's no
undefine to transient domains. There are two options: 1) leave
the file behind and let mgmt app remove it. 2) remove it
automatically as domain dies.
But, in some scenarios mgmt app may want to preserve the file,
copy it somewhere safe, and then copy it back when the domain is
starting again. And this wouldn't be possible with case 2). So,
even though case 1) leaves some files behind (possibly undeleted
for a long time), the files themselves are small (128K each). And
data loss is worse than full disk, isn't it?

For some reason, commit id '72b4151f' triggered a Coverity uninitialized
'reply' variable check when referenced within the for loop.

It seems Coverity doesn't know that flags will have to be either AFFECT_LIVE
or AFFECT_CONFIG after the virDomainLiveConfigHelperMethod call.

By adding a "sa_assert()" to confirm that fact, Coverity is happy again.

After a disk is hotunplugged a subsequent call to qemuDomainGetBlockIoTune
to get the --config settings of that disk will fail because the disk is no
longer found by qemuDiskPathToAlias causing an unexpected failure.

Since only the --live flag needs to have the disk device pointer, move the
fetch inside the (flags & VIR_DOMAIN_AFFECT_LIVE) condition. This will also
affect the results if no flags are provided or the --current flag is provided.

In bracket-spacing.pl, the current $line is being modified in $data.
That, however, spoils that $data for another check.  Introduce new
$tmpdata variable that can be used for temporary modifications.  The
difference between $data and $line is that $data are as much cleaned as
possible from non-code blocks and these changes must be kept.
