Commit a6c7040fb09 restricted the rtc-reset-reinjection command to the I386 target. Restrict the "qapi/qapi-commands-misc-target.h" header to it too.

2019-10-23runstate: ignore exit request in finish migrate stateLaurent Vivier
Trying to reboot a VM while a migration is running can move to the prelaunch state (because of the reset) while the runstate is in finish migrate state. As the logical step after the finish migrate is postmigrate, this can create an invalid state transition from prelaunch state to postmigrate state and this raises an error and aborts: invalid runstate transition: 'prelaunch' -> 'postmigrate' As we are not able to manage reset in finish migrate state the best we can do is to ignore any changes and delay them until the next state which should be postmigrate and which should allow this kind of transition.

2019-10-22hw/timer/exynos4210_mct: Initialize ptimer before starting itGuenter Roeck
When booting a recent Linux kernel, the qemu message "Timer with delta zero, disabling" is seen, apparently because a ptimer is started before being initialized. Fix the problem by initializing the offending ptimer before starting it. The bug is effectively harmless in the old QEMUBH setup because the sequence of events is: * the delta zero means the timer expires immediately * ptimer_reload() arranges for exynos4210_gfrc_event() to be called * ptimer_reload() notices the zero delta and disables the timer * later, the QEMUBH runs, and exynos4210_gfrc_event() correctly configures the timer and restarts it In the new transaction based API the bug is still harmless, but differences of when the callback function runs mean the message is not printed any more: * ptimer_run() does nothing as it's inside a transaction block * ptimer_transaction_commit() sees it has work to do and calls ptimer_reload() * the zero delta means the timer expires immediately * ptimer_reload() calls exynos4210_gfrc_event() directly * exynos4210_gfrc_event() configures the timer * the delta is no longer zero so ptimer_reload() doesn't complain (the zero-delta test is after the trigger-callback in the ptimer_reload() function) Regardless, the behaviour here was not intentional, and we should just program the ptimer correctly to start with.

2019-10-22block/nbd: nbd reconnectVladimir Sementsov-Ogievskiy
Implement reconnect. To achieve this: 1. add new modes: connecting-wait: means, that reconnecting is in progress, and there were small number of reconnect attempts, so all requests are waiting for the connection. connecting-nowait: reconnecting is in progress, there were a lot of attempts of reconnect, all requests will return errors. two old modes are used too: connected: normal state quit: exiting after fatal error or on close Possible transitions are: * -> quit connecting-* -> connected connecting-wait -> connecting-nowait (transition is done after reconnect-delay seconds in connecting-wait mode) connected -> connecting-wait 2. Implement reconnect in connection_co. So, in connecting-* mode, connection_co, tries to reconnect unlimited times. 3. Retry nbd queries on channel error, if we are in connecting-wait state.

2019-10-22qapi: Allow introspecting fix for savevm's cooperation with blockdevPeter Krempa
'savevm' was buggy as it considered all monitor-owned block device nodes for snapshot. With the introduction of -blockdev, the common usage made all nodes including protocol and backing file nodes be monitor-owned and thus considered for snapshot. This is a problem since the 'file' protocol nodes can't have internal snapshots and it does not make sense to take snapshot of nodes representing backing files. This was fixed by commit 05f4aced658a02b02. Clients need to be able to detect whether this fix is present. Since savevm does not have an QMP alternative, add the feature for the 'human-monitor-command' backdoor which is used to call this command in modern use.

2019-10-22qapi: Split up scripts/qapi/common.pyMarkus Armbruster
The QAPI code generator clocks in at some 3100 SLOC in 8 source files. Almost 60% of the code is in qapi/common.py. Split it into more focused modules: * Move QAPISchemaPragma and QAPISourceInfo to qapi/source.py. * Move QAPIError and its sub-classes to qapi/error.py. * Move QAPISchemaParser and QAPIDoc to parser.py. Use the opportunity to put QAPISchemaParser first. * Move check_expr() & friends to qapi/expr.py. Use the opportunity to put the code into a more sensible order. * Move QAPISchema & friends to qapi/schema.py * Move QAPIGen and its sub-classes, ifcontext, QAPISchemaModularCVisitor, and QAPISchemaModularCVisitor to qapi/gen.py * Delete camel_case(), it's unused since commit e98859a9b9 "qapi: Clean up after recent conversions to QAPISchemaVisitor" A number of helper functions remain in qapi/common.py. I considered moving the code generator helpers to qapi/gen.py, but decided not to. Perhaps we should rewrite them as methods of QAPIGen some day.

2019-10-22hw/i386: Introduce the microvm machine typeSergio Lopez
microvm is a machine type inspired by Firecracker and constructed after its machine model. It's a minimalist machine type without PCI nor ACPI support, designed for short-lived guests. microvm also establishes a baseline for benchmarking and optimizing both QEMU and guest operating systems, since it is optimized for both boot time and footprint.

2019-10-22roms: add microvm-bios (qboot) as binary and git submoduleSergio Lopez
qboot is a minimalist x86 firmware for booting Linux kernels. It does the mininum amount of work required for the task, and it's able to boot both PVH images and bzImages without relying on option roms. This characteristics make it an ideal companion for the microvm machine type.
