| * shutdown: Expose bool cause in SHUTDOWN and RESET eventsEric Blake2017-05-231-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Libvirt would like to be able to distinguish between a SHUTDOWN event triggered solely by guest request and one triggered by a SIGTERM or other action on the host. While qemu_kill_report() was already able to give different output to stderr based on whether a shutdown was triggered by a host signal (but NOT by a host UI event, such as clicking the X on the window), that information was then lost to management. The previous patches improved things to use an enum throughout all callsites, so now we have something ready to expose through QMP. Note that for now, the decision was to expose ONLY a boolean, rather than promoting ShutdownCause to a QAPI enum; this is because libvirt has not expressed an interest in anything finer-grained. We can still add additional details, in a backwards-compatible manner, if a need later arises (if the addition happens before 2.10, we can replace the bool with an enum; otherwise, the enum will have to be in addition to the bool); this patch merely adds a helper shutdown_caused_by_guest() to map the internal enum into the external boolean. Update expected iotest outputs to match the new data (complete coverage of the affected tests is obtained by -raw, -qcow2, and -nbd). Here is output from 'virsh qemu-monitor-event --loop' with the patch installed: event SHUTDOWN at 1492639680.731251 for domain fedora_13: {"guest":true} event STOP at 1492639680.732116 for domain fedora_13: <null> event SHUTDOWN at 1492639680.732830 for domain fedora_13: {"guest":false} Note that libvirt runs qemu with -no-shutdown: the first SHUTDOWN event was triggered by an action I took directly in the guest (shutdown -h), at which point qemu stops the vcpus and waits for libvirt to do any final cleanups; the second SHUTDOWN event is the result of libvirt sending SIGTERM now that it has completed cleanup. Libvirt is already smart enough to only feed the first qemu SHUTDOWN event to the end user (remember, virsh qemu-monitor-event is a low-level debugging interface that is explicitly unsupported by libvirt, so it sees things that normal end users do not); changing qemu to emit SHUTDOWN only once is outside the scope of this series.

| * shutdown: Add source information to SHUTDOWN and RESETEric Blake2017-05-231-10/+8Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

| * shutdown: Preserve shutdown cause through replayEric Blake2017-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the recent addition of ShutdownCause, we want to be able to pass a cause through any shutdown request, and then faithfully replay that cause when later replaying the same sequence. The easiest way is to expand the reply event mechanism to track a series of values for EVENT_SHUTDOWN, one corresponding to each value of ShutdownCause. We are free to change the replay stream as needed, since there are already no guarantees about being able to use a replay stream by any other version of qemu than the one that generated it. The cause is not actually fed back until the next patch changes the signature for requesting a shutdown; a TODO marks that upcoming change. Yes, this uses the gcc/clang extension of a ranged case label, but this is not the first time we've used non-C99 constructs.

| * shutdown: Prepare for use of an enum in reset/shutdown_requestEric Blake2017-05-231-20/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to track why a guest was shutdown; in particular, being able to tell the difference between a guest request (such as ACPI request) and host request (such as SIGINT) will prove useful to libvirt. Since all requests eventually end up changing shutdown_requested in vl.c, the logical change is to make that value track the reason, rather than its current 0/1 contents. Since command-line options control whether a reset request is turned into a shutdown request instead, the same treatment is given to reset_requested. This patch adds an internal enum ShutdownCause that describes reasons that a shutdown can be requested, and changes qemu_system_reset() to pass the reason through, although for now nothing is actually changed with regards to what gets reported. The enum could be exported via QAPI at a later date, if deemed necessary, but for now, there has not been a request to expose that much detail to end clients. For the most part, we turn 0 into SHUTDOWN_CAUSE_NONE, and 1 into SHUTDOWN_CAUSE_HOST_ERROR; the only specific case where we have enough information right now to use a different value is when we are reacting to a host signal. It will take a further patch to edit all call-sites that can trigger a reset or shutdown request to properly pass in any other reasons; this patch includes TODOs to point such places out. qemu_system_reset() trades its 'bool report' parameter for a 'ShutdownCause reason', with all non-zero values having the same effect; this lets us get rid of the weird #defines for VMRESET_* as synonyms for bools.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally CPU threads were by default assigned in round-robin fashion. However it was causing issues in guest since CPU threads from the same socket/core could be placed on different NUMA nodes. Commit fb43b73b (pc: fix default VCPU to NUMA node mapping) fixed it by grouping threads within a socket on the same node introducing cpu_index_to_socket_id() callback and commit 20bb648d (spapr: Fix default NUMA node allocation for threads) reused callback to fix similar issues for SPAPR machine even though socket doesn't make much sense there. As result QEMU ended up having 3 default distribution rules used by 3 targets /virt-arm, spapr, pc/. In effort of moving NUMA mapping for CPUs into possible_cpus, generalize default mapping in numa.c by making boards decide on default mapping and let them explicitly tell generic numa code to which node a CPU thread belongs to by replacing cpu_index_to_socket_id() with @cpu_index_to_instance_props() which provides default node_id assigned by board to specified cpu_index.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The new command line option -blockdev works like QMP command blockdev-add. The option argument may be given in JSON syntax, exactly as in QMP. Example usage: -blockdev '{"node-name": "foo", "driver": "raw", "file": {"driver": "file", "filename": "foo.img"} }' The JSON argument doesn't exactly blend into the existing option syntax, so the traditional KEY=VALUE,... syntax is also supported, using dotted keys to do the nesting: -blockdev node-name=foo,driver=raw,file.driver=file,file.filename=foo.img This does not yet support lists, but that will be addressed shortly. Note that calling qmp_blockdev_add() (say via qmp_marshal_block_add()) right away would crash. We need to stash the configuration for later instead. This is crudely done, and bypasses QemuOpts, even though storing configuration is what QemuOpts is for. Need to revamp option infrastructure to support QAPI types like BlockdevOptions.

* qmp: Dumb down how we run QMP command registrationMarkus Armbruster2017-03-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way we get QMP commands registered is high tech: * qapi-commands.py generates qmp_init_marshal() that does the actual work * it also generates the magic to register it as a MODULE_INIT_QAPI function, so it runs when someone calls module_call_init(MODULE_INIT_QAPI) * main() calls module_call_init() QEMU needs to register a few non-qapified commands. Same high tech works: monitor.c has its own qmp_init_marshal() along with the magic to make it run in module_call_init(MODULE_INIT_QAPI). QEMU also needs to unregister commands that are not wanted in this build's configuration (commit 5032a16). Simple enough: qmp_unregister_commands_hack(). The difficulty is to make it run after the generated qmp_init_marshal(). We can't simply run it in monitor.c's qmp_init_marshal(), because the order in which the registered functions run is indeterminate. So qmp_init_marshal() registers qmp_unregister_commands_hack() separately. Since registering *appends* to the list of registered functions, this will make it run after all the functions that have been registered already. I suspect it takes a long and expensive computer science education to not find this silly. Dumb it down as follows: * Drop MODULE_INIT_QAPI entirely * Give the generated qmp_init_marshal() external linkage. * Call it instead of module_call_init(MODULE_INIT_QAPI) * Except in QEMU proper, call new monitor_init_qmp_commands() that in turn calls the generated qmp_init_marshal(), registers the additional commands and unregisters the unwanted ones.

| | | | | | | | | | | | | | | | | | | In commit af6bf1328ef90fae617857c02697e0174b84d596 (May 2011), ide-hd, ide-cd and scsi-cd have been added to disable default cdrom, "or else you can't put one on secondary master without -nodefaults". Make it the same for scsi-hd, so you can put one on scsi-id 2 without using -nodefaults. scsi-hd has probably been forgotten, as it has been added in the preceding commit (b443ae67130d32ad06b06fc9aa6d04d05ccd93ce). Affected users are the ones using a machine with SCSI devices and start QEMU with -device scsi-hd but without -device scsi-cd or -cdrom In that case, the default cdrom device will disappear instead of being empty.

It will call qemu_char_open() to open/intialize the chardev with the ChardevCommon *backend settings. The CharDriver::create() callback is turned into a ChardevClass::open() which is called from the newly introduced qemu_chardev_open(). "chardev-gdb" and "chardev-hci" are internal chardev and aren't creatable directly with -chardev. Use a new internal flag to disable them. We may want to use TYPE_USER_CREATABLE interface instead, or perhaps allow -chardev usage. Although in general we keep typename and macros private, unless the type is being used by some other file, in this patch, all types and common helper macros for qemu-char.c are in char.h.
