* hw/ide: remove 'ide-drive' deviceDaniel P. Berrangé2021-03-181-1/+0Star

* usb: Un-deprecate -usbdevice (except for -usbdevice audio which gets removed)Thomas Huth2021-03-151-2/+0Star
| | | | | | | | | | | | | | | | | When trying to remove the -usbdevice option, there were complaints that "-usbdevice braille" is still a very useful shortcut for some people. Thus we never remove this option. Since it's not such a big burden to keep it around, and it's also convenient in the sense that you don't have to worry to enable a host controller explicitly with this option, we should remove it from he deprecation list again. However, there is one exception: "-usbdevice audio" should go away, since audio devices without "audiodev=..." parameter are also on the deprecation list and you cannot use "-usbdevice audio" with "audiodev".

* trace: skip qemu_set_log_filename if no "-D" option was passedPaolo Bonzini2021-03-061-1/+3
| | | | | | | | | | | | | | | | | When the "simple" backend is not active but the "log" backend is, both "-trace file=" and "-D" will result in a call to qemu_set_log_filename. Unfortunately, QEMU was also calling qemu_set_log_filename if "-D" was not passed, so the "-trace file=" option had no effect and the tracepoints went back to stderr. Fortunately we can just skip qemu_set_log_filename in that case, because the log backend will initialize itself just fine as soon as qemu_set_log is called, also in qemu_process_early_options.

* vl.c: do not execute trace_init_backends() before daemonizingDaniel Henrique Barboza2021-03-061-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit v5.2.0-190-g0546c0609c ("vl: split various early command line options to a separate function") moved the trace backend init code to the qemu_process_early_options(). Which is now being called before os_daemonize() via qemu_maybe_daemonize(). Turns out that this change of order causes a problem when executing QEMU in daemon mode and with CONFIG_TRACE_SIMPLE. The trace thread is now being created by the parent, and the parent is left waiting for a trace file flush that was registered via st_init(). The result is that the parent process never exits. To reproduce, fire up a QEMU process with -daemonize and with CONFIG_TRACE_SIMPLE enabled. Two QEMU process will be left in the host: $ sudo ./x86_64-softmmu/qemu-system-x86_64 -S -no-user-config -nodefaults \ -nographic -machine none,accel=kvm:tcg -daemonize $ ps axf | grep qemu 529710 pts/3 S+ 0:00 | \_ grep --color=auto qemu 529697 ?

Libvirt waits for the parent process to exit to be sure that the QMP monitor is available in the daemonized process to fetch QEMU capabilities, and as is now Libvirt hangs at daemon start waiting for the parent thread to exit. The fix is simple: just move the trace backend related code back to be executed after daemonizing.

* | confidential guest support: Introduce cgs "ready" flagDavid Gibson2021-02-081-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The platform specific details of mechanisms for implementing confidential guest support may require setup at various points during initialization. Thus, it's not really feasible to have a single cgs initialization hook, but instead each mechanism needs its own initialization calls in arch or machine specific code. However, to make it harder to have a bug where a mechanism isn't properly initialized under some circumstances, we want to have a common place, late in boot, where we verify that cgs has been initialized if it was requested. This patch introduces a ready flag to the ConfidentialGuestSupport base type to accomplish this, which we verify in qemu_machine_creation_done().

* runstate: cleanup reboot and panic actionsPaolo Bonzini2021-01-211-1/+1
| | | | | | | | | | | | | | | | | | The possible choices for panic, reset and watchdog actions are inconsistent. "-action panic=poweroff" should be renamed to "-action panic=shutdown" on the command line. This is because "-action panic=poweroff" and "-action watchdog=poweroff" have slightly different semantics, the first does an unorderly exit while the second goes through qemu_cleanup(). With this change, -no-shutdown would not have to change "-action panic=pause" "pause", just like it does not have to change the reset action. "-action reboot=none" should be renamed to "-action reboot=reset". This should be self explanatory, since for example "-action panic=none" lets the guest proceed without taking any action.

* vl: Add option to avoid stopping VM upon guest panicAlejandro Jimenez2020-12-151-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current default action of pausing a guest after a panic event is received leaves the responsibility to resume guest execution to the management layer. The reasons for this behavior are discussed here: https://lore.kernel.org/qemu-devel/52148F88.5000509@redhat.com/ However, in instances like the case of older guests (Linux and Windows) using a pvpanic device but missing support for the PVPANIC_CRASHLOADED event, and Windows guests using the hv-crash enlightenment, it is desirable to allow the guests to continue running after sending a PVPANIC_PANICKED event. This allows such guests to proceed to capture a crash dump and automatically reboot without intervention of a management layer. Add an option to avoid stopping a VM after a panic event is received, by passing: -action panic=none in the command line arguments, or during runtime by using an upcoming QMP command.

* vl: allow -incoming defer with -preconfigPaolo Bonzini2020-12-151-3/+2Star
| | | | | | | | Now that there is no RUN_STATE_PRECONFIG anymore that can conflict with RUN_STATE_INMIGRATE, we can allow -incoming defer with -preconfig. Reviewed-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* vl: remove separate preconfig main_loopPaolo Bonzini2020-12-151-54/+41Star
| | | | | | | | | | | | | Move post-preconfig initialization to the x-exit-preconfig. If preconfig is not requested, just exit preconfig mode immediately with the QMP command. As a result, the preconfig loop will run with accel_setup_post and os_setup_post restrictions (xen_restrict, chroot, etc.) already done.

* remove preconfig statePaolo Bonzini2020-12-151-11/+2Star
| | | | | | | | | | The preconfig state is only used if -incoming is not specified, which makes the RunState state machine more tricky than it need be. However there is already an equivalent condition which works even with -incoming, namely qdev_hotplug. Use it instead of a separate runstate.

| | | | | | | | | serial_hd(i) is NULL if and only if i >= serial_max_hds(). Test serial_hd(i) instead of bounding the loop at serial_max_hds(), thus removing one more function that vl.c is expected to export.

| | | | | | | | | | Complement the previous patch by starting the VM with a QMP command. The plan is that the user will be able to do the same, invoking two commands "finish-machine-init" and "cont" instead of "x-exit-preconfig".

* migration, vl: start migration via qmp_migrate_incomingPaolo Bonzini2020-12-101-4/+7
| | | | | | | | | | | | | | | Make qemu_start_incoming_migration local to migration/migration.c. By using the runstate instead of a separate flag, vl need not do anything to setup deferred incoming migration. qmp_migrate_incoming also does not need the deferred_incoming flag anymore, because "-incoming PROTOCOL" will clear the "once" flag before the main loop starts. Therefore, later invocations of the migrate-incoming command will fail with the existing "The incoming migration has already been started" error message.

* vl: initialize displays before preconfig loopPaolo Bonzini2020-12-101-21/+36
| | | | | | | | | | | | | | | Displays should be available before the monitor starts, so that it is possible to use the graphical console to interact with the monitor itself. This patch is quite ugly, but all this is temporary. The double call to qemu_init_displays will go away as soon we can unify machine initialization between the preconfig and "normal" flows, and so will the preconfig_exit_requested variable (that is only preconfig_requested remains).
