f1ce954b32 tests: qemumonitor: Prepare for more test data in testBlockNodeNameDetect
Rename 'json' and related variables to 'nodeNameJson'. Also rename the
test files along. This is a preparation for modifying how we detect node
names which will also require data from 'query-blockstats'.

2277edb964 qemu: handle missing bind host/service on chardev hotplug
On domain startup, bind host or bind service can be omitted
and we will format a working command line.

Extend this to hotplug as well and specify the service to QEMU
even if the host is missing.

ccac446545 qemu: domain: Use vcpu 'node-id' property and pass it back to qemu
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'/>
    </numa>

3d06cb96fb qemu: Add TLS params to _qemuMonitorMigrationParams
Add the fields to support setting tls-creds and tls-hostname during
a migration (either source or target). Modify the query migration
function to check for the presence and set the field for future
consumers to determine which of 3 conditions is being met (NULL,
present and set to "", or present and sent to something). These
correspond to qemu commit id '4af245dc3' which added support to
default the value to "" and allow setting (or resetting) to ""
in order to disable. This reset option allows libvirt to properly
use the tls-creds and tls-hostname parameters.

Modify code paths that either allocate or use stack space in order
to call qemuMigrationParamsClear or qemuMigrationParamsFree for cleanup.

a1adfb0f06 qemu: Add support for unavailable-features
QEMU 2.8.0 adds support for unavailable-features in
query-cpu-definitions reply. The unavailable-features array lists CPU
features which prevent a corresponding CPU model from being usable on
current host. It can only be used when all the unavailable features are
disabled. Empty array means the CPU model can be used without
modifications.

We can use unavailable-features for providing CPU model usability info
in domain capabilities XML:

0d130a011c qemu: monitor: Open-code retrieval of wr_highest_offset
Instead of using qemuMonitorJSONDevGetBlockExtent (which I plan to

Additionally add a flag that will be set when the wr_highest_offset was
extracted correctly so that callers can act according to that.

The test case addition should help make sure that everything works.

ab393383c8 qemu: Always set migration capabilities
We used to set migration capabilities only when a user asked for them in
flags. This is fine when migration succeeds since the QEMU process is
killed in the end but in case migration fails or if it's cancelled, some
capabilities may remain turned on with no way to turn them off. To fix
that, migration capabilities have to be turned on if requested but
explicitly turned off in case they were not requested but QEMU supports
them.

eef91f9470 blockcopy: add qemu implementation of new tunables
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
value passed to some other parameter).  I don't see that a
capability check will help, so we'll just live with it (and it
has since been improved in upstream qemu).

b606bbb416 qemu: Issue rtc-reset-reinjection command after guest-set-time
https://bugzilla.redhat.com/show_bug.cgi?id=1103245

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.

47549d5a17 blockjob: allow omitted arguments to QMP block-commit
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.

prototype.

bdce278984 Add qemuMonitorJSONGetObjectProperty() method for QMP qom-get command
Add a new qemuMonitorJSONGetObjectProperty() method to support invocation
of the 'qom-get' JSON monitor command with a provided path, property, and
expected data type return. The qemuMonitorJSONObjectProperty is similar to
virTypedParameter; however, a future patch will extend it a bit to include
a void pointer to balloon driver statistic data.

NOTE: The ObjectProperty structures and API are added only for the
      purpose of the qemumonitorjsontest

The provided test will execute a qom-get on "/machine/i440fx" which will
return a property "realized".

d76a89780b Add qemuMonitorJSONGetObjectListPaths() method for QMP qom-list command
Add a new qemuMonitorJSONGetObjectListPaths() method to support invocation
of the 'qom-list' JSON monitor command with a provided path.

NOTE: The ListPath structures and API's are added only for the

The returned list of paired data fields of "name" and "type" that can
be used to peruse QOM configuration data and eventually utilize for the
balloon statistics.

The test does a "{"execute":"qom-list", "arguments": { "path": "/"}}" which
returns "{"return": [{"name": "machine", "type": "child<container>"},
{"name": "type", "type": "string"}]}" resulting in a return of an array
of 2 elements with [0].name="machine", [0].type="child<container>".  The [1]
entry appears to be a header that could be used some day via a command such
as "virsh qemuobject --list" to format output.

bd56d0d813 qemu: query command line options in QMP
Ever since the conversion to using only QMP for probing features
of qemu 1.2 and newer, we have been unable to detect features
that are added only by additional command line options.  For
example, we'd like to know if '-machine mem-merge=on' (added
in qemu 1.5) is present.  To do this, we will take advantage
of qemu 1.5's query-command-line-parameters QMP call [1].

This patch wires up the framework for probing the command results;
if the QMP command is missing, or if a particular command line
option does not output any parameters (for example, -net uses
a polymorphic parser, which showed up as no parameters as of qemu
1.5), we silently treat that command as having no results.

9ea249e7d9 virCaps: get rid of defaultDiskDriverName
This patch removes the defaultDiskDriverName from the virCaps
structure. This particular default value is used only in the qemu driver
so this patch uses the recently added callback to fill the driver name
if it's needed instead of propagating it through virCaps.

27cf98e2d1 virCaps: conf: start splitting out irrelevat data
The virCaps structure gathered a ton of irrelevant data over time that.
The original reason is that it was propagated to the XML parser
functions.

This patch aims to create a new data structure virDomainXMLConf that
will contain immutable data that are used by the XML parser. This will
allow two things we need:

1) Get rid of the stuff from virCaps

2) Allow us to add callbacks to check and add driver specific stuff
after domain XML is parsed.

This first attempt removes pointers to private data allocation functions
to this new structure and update all callers and function that require
them.
