2023-05-10build: move COLO under CONFIG_REPLICATIONVladimir Sementsov-Ogievskiy
We don't allow to use x-colo capability when replication is not configured. So, no reason to build COLO when replication is disabled, it's unusable in this case. Note also that the check in migrate_caps_check() is not the only restriction: some functions in migration/colo.c will just abort if called with not defined CONFIG_REPLICATION, for example: migration_iteration_finish() case MIGRATION_STATUS_COLO: migrate_start_colo_process() colo_process_checkpoint() abort() It could probably make sense to have possibility to enable COLO without REPLICATION, but this requires deeper audit of colo & replication code, which may be done later if needed.

2023-05-02hmp: Add 'one-insn-per-tb' command equivalent to 'singlestep'Peter Maydell
The 'singlestep' HMP command is confusing, because it doesn't actually have anything to do with single-stepping the CPU. What it does do is force TCG emulation to put one guest instruction in each TB, which can be useful in some situations. Create a new HMP command 'one-insn-per-tb', so we can document that 'singlestep' is just a deprecated synonym for it, and eventually perhaps drop it. We aren't obliged to do deprecate-and-drop for HMP commands, but it's easy enough to do so, so we do.

2022-10-28qapi: net: add stream and dgram netdevsLaurent Vivier
Copied from socket netdev file and modified to use SocketAddress to be able to introduce new features like unix socket. "udp" and "mcast" are squashed into dgram netdev, multicast is detected according to the IP address type. "listen" and "connect" modes are managed by stream netdev. An optional parameter "server" defines the mode (off by default) The two new types need to be parsed the modern way with -netdev, because with the traditional way, the "type" field of netdev structure collides with the "type" field of SocketAddress and prevents the correct evaluation of the command line option. Moreover the traditional way doesn't allow to use the same type (SocketAddress) several times with the -netdev option (needed to specify "local" and "remote" addresses). The previous commit paved the way for parsing the modern way, but omitted one detail: how to pick modern vs. traditional, in netdev_is_modern(). We want to pick based on the value of parameter "type". But how to extract it from the option argument? Parsing the option argument, either the modern or the traditional way, extracts it for us, but only if parsing succeeds. If parsing fails, there is no good option. No matter which parser we pick, it'll be the wrong one for some arguments, and the error reporting will be confusing. Fortunately, the traditional parser accepts *anything* when called in a certain way. This maximizes our chance to extract the value of "type", and in turn minimizes the risk of confusing error reporting.

2022-10-17qmp/hmp, device_tree.c: introduce dumpdtbDaniel Henrique Barboza
To save the FDT blob we have the '-machine dumpdtb=<file>' property. With this property set, the machine saves the FDT in <file> and exit. The created file can then be converted to plain text dts format using 'dtc'. There's nothing particularly sophisticated into saving the FDT that can't be done with the machine at any state, as long as the machine has a valid FDT to be saved. The 'dumpdtb' command receives a 'filename' parameter and, if the FDT is available via current_machine->fdt, save it in dtb format to 'filename'. In short, this is a '-machine dumpdtb' that can be fired on demand via QMP/HMP. This command will always be executed in-band (i.e. holding BQL), avoiding potential race conditions with machines that might change the FDT during runtime (e.g. PowerPC 'pseries' machine).

2022-07-20softmmu/dirtylimit: Implement dirty page rate limitHyman Huang(黄勇)
Implement dirtyrate calculation periodically basing on dirty-ring and throttle virtual CPU until it reachs the quota dirty page rate given by user. Introduce qmp commands "set-vcpu-dirty-limit", "cancel-vcpu-dirty-limit", "query-vcpu-dirty-limit" to enable, disable, query dirty page limit for virtual CPU. Meanwhile, introduce corresponding hmp commands "set_vcpu_dirty_limit", "cancel_vcpu_dirty_limit", "info vcpu_dirty_limit" so the feature can be more usable. "query-vcpu-dirty-limit" success depends on enabling dirty page rate limit, so just add it to the list of skipped command to ensure qmp-cmd-test run successfully.

2022-04-25block: add 'force' parameter to 'blockdev-change-medium' commandDenis V. Lunev
'blockdev-change-medium' is a convinient wrapper for the following sequence of commands: * blockdev-open-tray * blockdev-remove-medium * blockdev-insert-medium * blockdev-close-tray and should be used f.e. to change ISO image inside the CD-ROM tray. Though the guest could lock the tray and some linux guests like CentOS 8.5 actually does that. In this case the execution if this command results in the error like the following: Device 'scsi0-0-1-0' is locked and force was not specified, wait for tray to open and try again. This situation is could be resolved 'blockdev-open-tray' by passing flag 'force' inside. Thus is seems reasonable to add the same capability for 'blockdev-change-medium' too. Signed-off-by: Denis V.

2021-01-23hmp: remove "change vnc TARGET" commandPaolo Bonzini
The HMP command \"change vnc TARGET\" is messy: - it takes an ugly shortcut to determine if the option has an "id", with incorrect results if "id=" is not preceded by an unescaped comma. - it deletes the existing QemuOpts and does not try to rollback if the parsing fails (which is not causing problems, but only due to how VNC options are parsed) - because it uses the same parsing function as "-vnc", it forces the latter to not support "-vnc help". On top of this, it uses a deprecated QMP command, thus getting in the way of removing the QMP command. Since the usecase for the command is not clear, just remove it and send "change vnc password" directly to the QMP "change-vnc-password" command.

We have four HMP commands which have a single-character abbreviated version: cont ('c'), quit ('q'), print ('p') and help ('h'). For cont, quit and print, we list the abbreviation first in the help documentation and the command name. This has the odd effect that in the full 'help' command list these commands end up sorted out of alphabetical order (they end up after all the other commands that start with the same letter). As it happens, the only place this currently changes the order is for 'cont'. Abbreviation first is also not a very logical order, and it doesn't match what we use for 'help' (which is 'help|?').

2020-11-04console: make QMP/HMP screendump run in coroutineMarc-André Lureau
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).

2020-10-09block: Convert 'block_resize' to coroutineKevin Wolf
block_resize performs some I/O that could potentially take quite some time, so use it as an example for the new 'coroutine': true annotation in the QAPI schema. bdrv_truncate() requires that we're already in the right AioContext for the BlockDriverState if called in coroutine context. So instead of just taking the AioContext lock, move the QMP handler coroutine to the context. Call blk_unref() only after switching back because blk_unref() may only be called in the main thread.

2020-06-17hmp: Make json format optional for qom-setDavid Hildenbrand
Commit 7d2ef6dcc1cf ("hmp: Simplify qom-set") switched to the json parser, making it possible to specify complex types. However, with this change it is no longer possible to specify proper sizes (e.g., 2G, 128M), turning the interface harder to use for properties that consume sizes. Let's switch back to the previous handling and allow to specify passing json via the "-j" parameter.

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.
