ThrottleGroup is converted to an object. This will allow the future
throttle block filter drive easy creation and configuration of throttle
groups in QMP and cli.
A new QAPI struct, ThrottleLimits, is introduced to provide a shared
struct for all throttle configuration needs in QMP.
ThrottleGroups can be created via CLI as
-object throttle-group,id=foo,x-iops-total=100,x-..
where x-* are individual limit properties. Since we can't add non-scalar
properties in -object this interface must be used instead. However,
setting these properties must be disabled after initialization because
certain combinations of limits are forbidden and thus configuration
changes should be done in one transaction. The individual properties
will go away when support for non-scalar values in CLI is implemented
and thus are marked as experimental.
ThrottleGroup also has a `limits` property that uses the ThrottleLimits
struct. It can be used to create ThrottleGroups or set the
configuration in existing groups as follows:
{ "execute": "object-add",
"arguments": {
"qom-type": "throttle-group",
"id": "foo",
"props" : {
"limits": {
"iops-total": 100
}
}
}
}
{ "execute" : "qom-set",
"arguments" : {
"path" : "foo",
"property" : "limits",
"value" : {
"iops-total" : 99
}
}
}
This also means a group's configuration can be fetched with qom-get.

This commit eliminates the 1:1 relationship between BlockBackend and
throttle group state. Users will be able to create multiple throttle
nodes, each with its own throttle group state, in the future. The
throttle group state cannot be per-BlockBackend anymore, it must be
per-throttle node. This is done by gathering ThrottleGroup membership
details from BlockBackendPublic into ThrottleGroupMember and refactoring
existing code to use the structure.

A command is a query if it has no side effect and yields a result.
Such commands are typically named query-FOO, but there are exceptions.
The basic idea is to find candidates with query-qmp-schema, filter out
the ones that aren't queries with an explicit blacklist, and test the
remaining ones against a QEMU with no special arguments.
The current blacklist is just add-fd.
The test can't do queries with arguments, because it knows nothing
about the arguments. No coverage for query-cpu-model-baseline,
query-cpu-model-comparison, query-cpu-model-expansion, query-rocker,
query-rocker-ports, query-rocker-of-dpa-flows, and
query-rocker-of-dpa-groups.
Most tested commands are expected to succeed. The test does not check
the return value then.
query-balloon and query-vm-generation-id are expected to fail because
they need a virtio-balloon / vmgenid device to succeed, and this test
is too dumb to set one up. Could be addressed later.
query-acpi-ospm-status and query-hotpluggable-cpus are expected to
fail because they require features provided only by special machine
types, and this test is too dumb to set that up. Could also be
addressed later.
Several commands may either be functional or stubs that always fail,
depending on build configuration. Ideally, the stubs shouldn't be in
query-qmp-schema, but that requires QAPI schema compile-time
configuration, which we don't have, yet. Until we do, we need to
figure out whether a command is a stub. When we have a suitable
CONFIG_FOO preprocessor symbol is available, use that. Else,
simply blacklist the command for now.
We get basic test coverage for the following commands, except as
noted:
qom-list-types
query-acpi-ospm-status (expected to fail)
query-balloon (expected to fail)
query-block
query-block-jobs
query-blockstats

Refactor nbd_read_eof to return 1 on success, 0 on eof, when no
data was read and <0 for other cases, because returned size of
read data is not actually used.

[eblake: tweak function comments, rebase to test 083 enhancements]
Signed-off-by: Eric Blake <eblake@redhat.com>
083 only tests TCP. Some failures might be specific to UNIX domain
sockets.
A few adjustments are necessary:
1. Generating a port number and waiting for server startup is
TCP-specific. Use the new nbd-fault-injector.py startup protocol to
fetch the address. This is a little more elegant because we don't
need netstat anymore.
2. The NBD filter does not work for the UNIX domain sockets URIs we
generate and must be extended.
3. Run all tests twice: once for TCP and once for UNIX domain sockets.

Currently 083 waits for the nbd-fault-injector.py server to start up by
looping until netstat shows the TCP listen socket.
The startup protocol can be simplified by passing a 0 port number to
nbd-fault-injector.py. The kernel will allocate a port in bind(2) and
the final port number can be printed by nbd-fault-injector.py.
This should make it slightly nicer and less TCP-specific to wait for
server startup. This patch changes nbd-fault-injector.py, the next one
will rewrite server startup in 083.

This is the follow-up patch that was discussed[*] as part of feedback to
qemu-iotest 194.
Changes in this patch:
- Supply 'job-id' parameter to `drive-mirror` invocation.
- Once migration completes, issue QMP `block-job-cancel` command on
the source QEMU to gracefully complete `drive-mirror` operation.
- Once the BLOCK_JOB_COMPLETED event is emitted, stop the NBD server
on the destination QEMU.
- Check for both the events: MIGRATION and BLOCK_JOB_COMPLETED.
With the above, the test will also be (almost) in sync with the
procedure outlined in the document 'live-block-operations.rst'[+]
(section: "QMP invocation for live storage migration with
``drive-mirror`` + NBD").

With some small modifications, we can also use the the netfilter,
the filter-mirror and the filter-redirector tests on s390x.
