2020-03-06block/rbd: Add support for ceph namespacesFlorian Florensa
Starting from ceph Nautilus, RBD has support for namespaces, allowing for finer grain ACLs on images inside a pool, and tenant isolation. In the rbd cli tool documentation, the new image-spec and snap-spec are : - [pool-name/[namespace-name/]]image-name - [pool-name/[namespace-name/]]image-name@snap-name When using an non namespace's enabled qemu, it complains about not finding the image called namespace-name/image-name, thus we only need to parse the image once again to find if there is a '/' in its name, and if there is, use what is before it as the name of the namespace to later pass it to rados_ioctx_set_namespace. rados_ioctx_set_namespace if called with en empty string or a null pointer as the namespace parameters pretty much does nothing, as it then defaults to the default namespace. The namespace is extracted inside qemu_rbd_parse_filename, stored in the qdict, and used in qemu_rbd_connect to make it work with both qemu-img, and qemu itself.

2020-03-06qemu-storage-daemon: Add --monitor optionKevin Wolf
This adds and parses the --monitor option, so that a QMP monitor can be used in the storage daemon. The monitor offers commands defined in the QAPI schema at storage-daemon/qapi/qapi-schema.json. The --monitor options currently allows to create multiple monitors with the same ID. This part of the interface is considered unstable. We will reject such configurations as soon as we have a design for the monitor subsystem to perform these checks. (In the system emulator, we depend on QemuOpts rejecting duplicate IDs.)

2020-03-06monitor: Create QAPIfied monitor_init()Kevin Wolf
This adds a new QAPI-based monitor_init() function. The existing monitor_init_opts() is rewritten to simply put its QemuOpts parameter into a visitor and pass the resulting QAPI object to monitor_init(). This will cause some change in those error messages for the monitor options in the system emulator that are now generated by the visitor rather than explicitly checked in monitor_init_opts().

2020-02-18qapi: Document meaning of 'ignore' BlockdevOnError for jobsKevin Wolf
It is not obvious what 'ignore' actually means for block jobs: It could be continuing the job and returning success in the end despite the error (no block job does this). It could also mean continuing and returning failure in the end (this is what stream does). And it can mean retrying the failed request later (this is what backup, commit and mirror do). This (somewhat inconsistent) behaviour was introduced and described for stream and mirror in commit 32c81a4a6ec. backup and commit were introduced later and use the same model as mirror.

2020-02-15qapi: Delete all the "foo: dropped in n.n" notesPeter Maydell
A handful of QAPI doc comments include lines like "ppcemb: dropped in 3.1". The doc comment parser will just put these into whatever the preceding section was; sometimes that's "Notes", and sometimes it's some random other section, as with "NetClientDriver" where the "'dump': dropped in 2.12" line ends up in the "Since:" section. This tends to render wrongly, more so in the upcoming rST generator, but sometimes even in the Texinfo, as in the case of QKeyCode: ac_bookmarks since 2.10 altgr, altgr_r: dropped in 2.10 Since commit 3264ffced3 (v4.2.0), we have a better place to tell users about deprecated and deleted functionality -- qemu-deprecated.texi. These "dropped in" remarks all predate it, and other feature drops of that vintage are not documented anywhere, so moving these to qemu-deprecated.texi makes little sense. Drop them instead.

2020-02-15qapi/migration.json: Replace _this_ with *this*Peter Maydell
The MigrationInfo::setup-time documentation is the only place where we use _this_ inline markup for emphasis, commonly rendered in italics. We would like to switch the doc comments to rST format, but rST doesn't recognize that markup and emits literal underscores. Switch to *this* instead. Changes markup to strong emphasis with Texinfo, commonly rendered as bold. With rST, it will go right back to emphasis / italics. rST also uses **this** for strong (commonly rendered bold) where Texinfo uses *this*. We have one place in the doc comments which uses strong/bold markup, in qapi/introspect.json: Note: the QAPI schema is also used to help define *internal* When we switch to rST that will be rendered as emphasis / italics. Markus (who wrote that) thinks that using emphasis / italics there is an improvement, so we leave that markup alone.

2020-02-15qapi: Fix indent level on doc comments in json filesPeter Maydell
The current doc generation doesn't care much about indentation levels, but we would like to switch to an rST format, and rST does care about indentation. Make the doc comments more strongly consistent about indentation for multiline constructs like: @arg: description line 1 description line 2 Returns: line one line 2 so that there is always exactly one space after the colon, and subsequent lines align with the first. This commit is a purely whitespace change, and it does not alter the generated .texi files (because the texi generation code strips away all the extra whitespace). This does mean that we end up with some over-length lines. Note that when the documentation for an argument fits on a single line like this: @arg: one line only then stray extra spaces after the ':' don't affect the rST output, so I have not attempted to methodically fix them, though the preference is a single space here too.

2020-01-06blkdebug: Allow taking/unsharing permissionsMax Reitz
Sometimes it is useful to be able to add a node to the block graph that takes or unshare a certain set of permissions for debugging purposes. This patch adds this capability to blkdebug. (Note that you cannot make blkdebug release or share permissions that it needs to take or cannot share, because this might result in assertion failures in the block layer. But if the blkdebug node has no parents, it will not take any permissions and share everything by default, so you can then freely choose what permissions to take and share.)

2020-01-05numa: Extend CLI to provide initiator information for numa nodesTao Xu
In ACPI 6.3 chapter 5.2.27 Heterogeneous Memory Attribute Table (HMAT), The initiator represents processor which access to memory. And in 5.2.27.3 Memory Proximity Domain Attributes Structure, the attached initiator is defined as where the memory controller responsible for a memory proximity domain. With attached initiator information, the topology of heterogeneous memory can be described. Add new machine property 'hmat' to enable all HMAT specific options. Extend CLI of "-numa node" option to indicate the initiator numa node-id. In the linux kernel, the codes in drivers/acpi/hmat/hmat.c parse and report the platform's HMAT tables. Before using initiator option, enable HMAT with -machine hmat=on.

2019-11-18bitmap: Enforce maximum bitmap name lengthEric Blake
We document that for qcow2 persistent bitmaps, the name cannot exceed 1023 bytes. It is inconsistent if transient bitmaps do not have to abide by the same limit, and it is unlikely that any existing client even cares about using bitmap names this long. It's time to codify that ALL bitmaps managed by qemu (whether persistent in qcow2 or not) have a documented maximum length.

2019-11-01target/arm/monitor: Introduce qmp_query_cpu_model_expansionAndrew Jones
Add support for the query-cpu-model-expansion QMP command to Arm. We do this selectively, only exposing CPU properties which represent optional CPU features which the user may want to enable/disable. Additionally we restrict the list of queryable cpu models to 'max', 'host', or the current type when KVM is in use. And, finally, we only implement expansion type 'full', as Arm does not yet have a "base" CPU type. More details and example queries are described in a new document (docs/arm-cpu-features.rst). Note, certainly more features may be added to the list of advertised features, e.g. 'vfp' and 'neon'. The only requirement is that we can detect invalid configurations and emit failures at QMP query time. For 'vfp' and 'neon' this will require some refactoring to share a validation function between the QMP query and the CPU realize functions.

2019-10-29migration: add new migration state wait-unplugJens Freimann
This patch adds a new migration state called wait-unplug. It is entered after the SETUP state if failover devices are present. It will transition into ACTIVE once all devices were succesfully unplugged from the guest. So if a guest doesn't respond or takes long to honor the unplug request the user will see the migration state 'wait-unplug'. In the migration thread we query failover devices if they're are still pending the guest unplug. When all are unplugged the migration continues. If one device won't unplug migration will stay in wait_unplug state.
