* net: do not exit on "netdev_add help" monitor commandPaolo Bonzini2020-11-241-0/+6
| | | | | | | | | | | | | "netdev_add help" is causing QEMU to exit because the code that invokes show_netdevs is shared between CLI and HMP processing. Move the check to the callers so that exit(0) remains only in the CLI flow. "netdev_add help" is not fixed by this patch; that is left for later work.

* console: make QMP/HMP screendump run in coroutineMarc-André Lureau2020-11-041-1/+2
| | | | | | | | | | | | | | | | | | | Thanks to the monitors' coroutine support (merge commit b7092cda1b3), the screendump handler can trigger a graphic_hw_update(), yield and let the main loop run until update is done. Then the handler is resumed, and ppm_save() will write the screen image to disk in the coroutine context. The IO is still blocking though, as the file is set blocking so far, this could be addressed by some future change (with other caveats).

* migration: Add block-bitmap-mapping parameterMax Reitz2020-08-211-0/+30
| | | | | | | | | | | | | | | | | | | This migration parameter allows mapping block node names and bitmap names to aliases for the purpose of block dirty bitmap migration. This way, management tools can use different node and bitmap names on the source and destination and pass the mapping of how bitmaps are to be transferred to qemu (on the source, the destination, or even both with arbitrary aliases in the migration stream). While touching this code, fix a bug where bitmap names longer than 255 bytes would fail an assertion in qemu_put_counted_string().

* migration/throttle: Add cpu-throttle-tailslow migration parameterKeqian Zhu2020-05-071-0/+8
| | | | | | | | | | | | | | | | | | | | | At the tail stage of throttling, the Guest is very sensitive to CPU percentage while the @cpu-throttle-increment is excessive usually at tail stage. If this parameter is true, we will compute the ideal CPU percentage used by the Guest, which may exactly make the dirty rate match the dirty rate threshold. Then we will choose a smaller throttle increment between the one specified by @cpu-throttle-increment and the one generated by ideal CPU percentage. Therefore, it is compatible to traditional throttling, meanwhile the throttle increment won't be excessive at tail stage. This may make migration time longer, and is disabled by default.

If we make this percentage higher, then we can tolerate higher dirty rate during migration, which means less impact on guest. The side effect of higher percentage is longer migration time.

| | | | | | | | | | | | | | | | | | | | | | | | | | In order to issue requests on an existing BlockBackend with the 'qemu-io' HMP command, allow specifying the BlockBackend not only with a BlockBackend name, but also with a qdev ID/QOM path for a device that owns the (possibly anonymous) BlockBackend. Because qdev names could be conflicting with BlockBackend and node names, introduce a -d option to explicitly address a device. If the option is not given, a BlockBackend or a node is addressed.

Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.
