Prior to qemu 2.5 the node names would not be generated, thus would be
missing from 'query-blockstats' and 'query-named-block-nodes'. Test that
the code correctly detects nothing.
Additionally make sure that a VM without disks does not cause problems.
The test case change is necessary as our test file checker does not play
well with empty files.
qemu 2.9 returns an extra layer in the backing data if a block job is
active. Add a test case to see whether our code properly detects and
ignores such layer.
The test data was prepared by creating a backing chain of qcow2 images
(with qemu-img and with libvirt's snapshot feature).
One of the layers was then merged back by doing a block-commit:
virsh blockcommit VM hda --top /var/lib/libvirt/images/b
and then a block-copy job was started and kept in synchronized phase:
virsh blockcopy VM hda /tmp/tgt.img --transient job

Add the blockstats data and fix the expected output.
Test data was created as:
qemu-img create -f qcow2 img0 10M
qemu-img create -f qcow2 -o "backing_fmt=qcow2,backing_file=img0" img1
qemu-img create -f qcow2 -o "backing_fmt=qcow2,backing_file=img1" img2

With the new approach we are actually able to correctly detect node
names for the two instances of the same backing file.
Test images were created as:
qemu-img create -f qcow2 /var/lib/libvirt/images/base.qcow2 10M
qemu-img create -f qcow2 \
-o "backing_fmt=qcow2,backing_file=/var/lib/libvirt/images/base.qcow2 \

qemu-img create -f qcow2 \
-o "backing_fmt=qcow2,backing_file=/var/lib/libvirt/images/base.qcow2 \

and then used for two separate disks.

Remove the complex and unreliable code which inferred the node name
hierarchy only from data returned by 'query-named-block-nodes'. It turns
out that query-blockstats contain the full hierarchy of nodes as
perceived by qemu so the inference code is not necessary.
In query blockstats, the 'parent' object corresponds to the storage
behind a storage volume and 'backing' corresponds to the lower level of
backing chain. Since all have node names this data can be really easily
used to detect node names.
In addition to the code refactoring the one remaining test case needed
to be fixed along.

vcpu properties gathered from query-hotpluggable cpus need to be passed
back to qemu. As qemu did not use the node-id property until now and
libvirt forgot to pass it back properly (it was parsed but not passed
around) we did not honor this.
This patch adds node-id to the structures where it was missing and
passes it around as necessary.
The test data was generated with a VM with following config:
<numa>
<cell id='0' cpus='0,2,4,6' memory='512000' unit='KiB'/>
<cell id='1' cpus='1,3,5,7' memory='512000' unit='KiB'/>

oVirt uses relative names with directories in them. Test such
configuration. Also tests a snapshot done with _REUSE_EXTERNAL and a
relative backing file pre-specified in the qcow2 metadata.
Since we have to match the images by filename a common backing image
will break the detection process. Add a test case to see that the code
correctly did not continue the detection process.

default the value to "" and allow setting (or resetting) to ""

Return whether a vcpu entry is hotpluggable or online so that upper
layers don't have to infer the information from other data.
Advantage is that this code can be tested by unit tests.
Power 8 platform's basic hotpluggable unit is a core rather than a
thread for x86_64 family. This introduces most of the complexity of the
matching code and thus needs to be tested.
The test data contain data captured from in-order cpu hotplug and
unplug operations.
During review it was reported that adding at least 11 vcpus creates a
collision of prefixes in the monitor matching algorithm. Add a test case
to verify that the problem won't happen.
As the combination algorithm is rather complex and ugly it's necessary
to make sure it works properly. Add test suite infrastructure for
testing it along with a basic test based on x86_64 platform.
To allow matching up the data returned by query-cpus to entries in the
query-hotpluggable-cpus reply for CPU hotplug it's necessary to extract
the QOM path as it's the only link between the two.
Prepare to extract more data by returning an array of structs rather than
just an array of thread ids. Additionally report fatal errors separately
from qemu not being able to produce data.
The first argument should be const char ** instead of
char **, because this is a search function and as such it
doesn't, and shouldn't, alter the haystack in any way.
This change means we no longer have to cast arrays of
immutable strings to arrays of mutable strings; we still
have to do the opposite, though, but that's reasonable.
Rather than pass the disks[i]->info.alias to qemuMonitorSetDrivePassphrase
and then generate the "drive-%s" alias from that, let's use qemuAliasFromDisk
prior to the call to generate the drive alias and then pass that along
thus removing the need to generate the alias from the monitor code.

Upstream qemu 1.4 added some drive-mirror tunables not present
when it was first introduced in 1.3. Management apps may want
to set these in some cases (for example, without tuning
granularity down to sector size, a copy may end up occupying
more bytes than the original because an entire cluster is
copied even when only a sector within the cluster is dirty,
although tuning it down results in more CPU time to do the
copy). I haven't personally needed to use the parameters, but
since they exist, and since the new API supports virTypedParams,
we might as well expose them.
Since the tuning parameters aren't often used, and omitted from
the QMP command when unspecified, I think it is safe to rely on
qemu 1.3 to issue an error about them being unsupported, rather
than trying to create a new capability bit in libvirt.
Meanwhile, all versions of qemu from 1.4 to 2.1 have a bug where
a bad granularity (such as non-power-of-2) gives a poor message:
error: internal error: unable to execute QEMU command 'drive-mirror': Invalid parameter 'drive-virtio-disk0'
because of abuse of QERR_INVALID_PARAMETER (which is supposed to
name the parameter that was given a bad value, rather than the

capability check will help, so we'll just live with it (and it
has since been improved in upstream qemu).

An advice appeared there on the qemu-devel list [1]. When a domain is
suspended and then resumed guest kernel is not aware of this. So we've
introduced virDomainSetTime API that resets the time within guest
using qemu-ga. On the other hand, qemu itself is trying to make RTC
beat faster to catch the difference. But if we don't tell qemu that
guest's time was reset via the other method, both mechanisms are
applied resulting in again wrong guest time. In order to avoid summing
both corrections we need to tell qemu that it should not use the RTC
injection if the guest time is set via guest agent.

To allow changing the name that is recorded in the overlay of the TOP
image used in a block commit operation, we need to specify the backing
name to qemu. This is done via the "backing-file" attribute to the
block-commit command.
We are about to turn on support for active block commit. Although
qemu 2.0 was the first version to mostly support it, that version
mis-handles 0-length files, and doesn't have anything available for
easy probing. But qemu 2.1 fixed bugs, and made life simpler by
letting the 'top' argument be optional. Unless someone begs for
active commit with qemu 2.0, for now we are just going to enable
it only by probing for qemu 2.1 behavior (anyone backporting active
commit can also backport the optional argument behavior). This
requires qemu.git commit 7676e2c597000eff3a7233b40cca768b358f9bc9.
Although all our actual uses of block-commit supply arguments for
both base and top, we can omit both arguments and use a bogus
device string to trigger an interesting behavior in qemu. All QMP
commands first do argument validation, failing with GenericError
if a mandatory argument is missing. Once that passes, the code
in the specific command gets to do further checking, and the qemu
developers made sure that if device is the only supplied argument,
then the block-commit code will look up the device first, with a
failure of DeviceNotFound, before attempting any further argument
validation (most other validations fail with GenericError). Thus,
the category of error class can reliably be used to decipher
whether the top argument was optional, which in turn implies a
working active commit. Since we expect our bogus device string to
trigger an error either way, the code is written to return a
distinct return value without spamming the logs.
