2018-08-31net: Remove the deprecated -tftp, -bootp, -redir and -smb optionsThomas Huth1-18/+0
These options likely do not work as expected as soon as the user tries to use more than one network interface at once. The parameters have been marked as deprecated since QEMU v2.6, so users had plenty of time to move their scripts to the new syntax. Time to remove the old parameters now.

kexec/kdump as well as the bootloader use a subcode of diagnose 308 that is supposed to reset the I/O subsystem but not comprise a full "reboot". With the latest refactoring this is now broken when -no-reboot is used or when libvirt acts on a reboot QMP event, for example a virt-install from iso images.

2018-06-28kvm: support -overcommit cpu-pm=on|offMichael S. Tsirkin1-1/+31
With this flag, kvm allows guest to control host CPU power state. This increases latency for other processes using same host CPU in an unpredictable way, but if decreases idle entry/exit times for the running VCPU, so to use it QEMU needs a hint about whether host CPU is overcommitted, hence the flag name. Follow-up patches will expose this capability to guest (using mwait leaf). Based on a patch by Wanpeng Li <kernellwp@gmail.com> . Signed-off-by: Michael S.

2018-06-28Deprecate the -enable-hax optionThomas Huth1-0/+1
We currently have got three ways of turning on the HAX accelerator: "-machine accel=hax", "-accel hax" and "-enable-hax". That's really confusing and overloaded. Since "-accel" is our preferred way to enable an accelerator nowadays, and "-accel hax" is even less to type than "-enable-hax", let's deprecate the "-enable-hax" option now. Note: While "-enable-kvm" is available since a long time and can hardly be removed since it is used in a lot of upper layer tools and scripts, the "-enable-hax" option is still rather new and not very widespread yet, so I think that it should be OK if we remove this in a couple of releases again (we'll see whether someone complains after seeing the deprecation message - then we could still reconsider to keep it if there a well-founded reasons).

2018-06-25vl.c: do not allow --daemonize in combination with --preconfig CLI optionIgor Mammedov1-0/+6
some users when using --daemonize expect that QEMU will parse CLI options, initialize VM and only then complete daemonzation by signalling lead process to exit and start listening on monitor socket. So users treat parent process exit as sync point to connect to QEMU's monitor. That however doesn't work when --preconfig options is used, since it provides monitor before completing daemonization and expects user to issue exit-preconfig command when additional configuration via monitor is finished. We also can't move completing daemonization before preconfig monitor becomes available, since that would imply: * partially loosing ability to configure QEMU instance in --preconfig mode since QEMU might drop privileges, chroot and do other things when daemonization is completed * lead to loss of error messages in case they would happen after daemonization Be proactive now and make options mutually exclusive, so users would get clear error message instead of waiting for lead process exit indefinitely before connecting to monitor. PS: In case someone would come up with usecase where both options should be enabled at the same time we could drop this restriction as far as daemonization point is left where it is now (os_setup_post).

2018-06-18monitor: move init global earlierPeter Xu1-6/+1
Before this patch, monitor fd helpers might be called even earlier than monitor_init_globals(). This can be problematic. After previous work, now monitor_init_globals() does not depend on accelerator initialization any more. Call it earlier (before CLI parsing; that's where the monitor APIs might be called) to make sure it is called before any of the monitor APIs.

2018-06-11cli: Don't run early event loop if no --preconfig was specifiedIgor Mammedov1-2/+2
After 047f7038f586d215 it is possible for event loop to run two times. First time whilst parsing command line options (the idea is to bring up monitor early so that management applications can tweak config before machine is initialized). And the second time is after everything is set up (this is the usual place). In both cases the event loop is called as main_loop_wait(nonblocking = false) which causes the event loop to block until at least one event occurred. Now, consider that somebody (i.e. libvirt) calls us with -daemonize. This operation is split in two steps. The main() calls os_daemonize() which fork()-s and then waits in read() until child notifies it via write(): /qemu.git $ ./x86_64-softmmu/qemu-system-x86_64 -S -daemonize \ -no-user-config -nodefaults -nographic main(): child: os_daemonize(): read(pipe[0]) main_loop(): main_loop_wait(false) os_setup_post(): write(pipe[1]) main_loop(): main_loop_wait(false) Here it can be clearly seen that main() does not exit until an event occurs, but at the same time nobody will touch the monitor socket until their exec("qemu-system-*") finishes. So the whole thing deadlocks. The solution is to not call main_loop_wait() unless --preconfig was specified (in which case caller knows they must connect to the socket before exec() finishes). Patch also fixes hang when -nodefaults option is used, which were causing QEMU hang in the early main_loop_wait() indefinitely by the same means (not calling main_loop_wait() unless --preconfig is present on CLI) Based on From: Michal Privoznik <mprivozn@redhat.com> Subject: [PATCH] cli: Don't run early event loop if no --preconfig was specified Message-Id: <ad910973c593c5ac2fed3a10ea958f7e9c12f82c.1527935663.git.mprivozn@redhat.com> Fixes: 047f7038f586d215 Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <1528207243-268226-2-git-send-email-imammedo@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

2018-05-30cli: add --preconfig optionIgor Mammedov1-1/+34
This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state, allowing the configuration of QEMU from QMP before the machine jumps into board initialization code of machine_run_board_init() The intent is to allow management to query machine state and additionally configure it using previous query results within one QEMU instance (i.e. eliminate the need to start QEMU twice, 1st to query board specific parameters and 2nd for actual VM start using query results for additional parameters). The new option complements -S option and could be used with or without it. The difference is that -S pauses QEMU when the machine is completely initialized with all devices wired up and ready to execute guest code (QEMU needs only to unpause VCPUs to let guest execute its code), while the "preconfig" option pauses QEMU early before board specific init callback (machine_run_board_init) is executed and allows the configuration of machine parameters which will be used by board init code. When early introspection/configuration is done, command 'exit-preconfig' should be used to exit RUN_STATE_PRECONFIG and transition to the next requested state (i.e. if -S is used then QEMU will pause the second time when board/device initialization is completed or start guest execution if -S isn't provided on CLI) PS: Initially 'preconfig' is planned to be used for configuring numa topology depending on board specified possible cpus layout.

2018-05-07vl: allow 'maxmem' without 'slot'David Hildenbrand1-15/+4
We will be able to have memory devices (e.g. virtio) not requiring the slot parameter (e.g. not exposed via ACPI). We still need the maxmem parameter to setup a proper memory region for device memory. And some architectures (e.g. s390x) will have to set up the maximum possible guest address space size based on the maxmem parameter. As far as I can see, all code (pc.c,spapr.c,ACPI code) should handle !slots just fine, even though maxmem is set.

2018-04-30hw/s390x: Allow to configure the consoles with the "-serial" parameterThomas Huth1-50/+0
The consoles ("sclpconsole" and "sclplmconsole") can only be configured with "-device" and "-chardev" so far. Other machines use the convenience option "-serial" to configure the default consoles, even for virtual consoles like spapr-vty on the pseries machine. So let's support this option on s390x, too. This way we can easily enable the serial console here again with "-nodefaults", for example: qemu-system-s390x -no-shutdown -nographic -nodefaults -serial mon:stdio ... which is way shorter than typing: qemu-system-s390x -no-shutdown -nographic -nodefaults \ -chardev stdio,id=c1,mux=on -device sclpconsole,chardev=c1 \ -mon chardev=c1 The -serial parameter can also be used if you only want to see the QEMU monitor on stdio without using -nodefaults, but not the console output. That's something that is pretty impossible with the current code today: qemu-system-s390x -no-shutdown -nographic -serial none While we're at it, this patch also maps the second -serial option to the "sclplmconsole", so that there is now an easy way to configure this second console on s390x, too, for example: qemu-system-s390x -no-shutdown -nographic -serial null -serial mon:stdio Additionally, the new code is also smaller than the old one and we have less s390x-specific code in vl.c :-) I've also checked that migration still works as expected by migrating a guest with console output back and forth between a qemu-system-s390x that has this patch and an instance without this patch.

Add new parameter to optionally enable Out-Of-Band for a QMP server. An example command line: ./qemu-system-x86_64 -chardev stdio,id=char0 \ -mon chardev=char0,mode=control,x-oob=on By default, Out-Of-Band is off. It is not allowed if either MUX or non-QMP is detected, since Out-Of-Band is currently only for QMP, and non-MUX chardev backends. Note that the client STILL has to request 'oob' during qmp_capabilities; in part because the x-oob command line option may disappear in the future if we decide the capabilities negotiation is sufficient.

There are many places where the monitor initializes its globals: - monitor_init_qmp_commands() at the very beginning - single function to init monitor_lock - in the first entry of monitor_init() using "is_first_init" Unify them a bit. monitor_lock is not used before monitor_init() (as confirmed by code analysis and gdb watchpoints); so we are safe delaying what was a constructor-time initialization of the mutex into the later first call to monitor_init().

2018-03-19Use cpu_create(type) instead of cpu_init(cpu_model)Igor Mammedov1-7/+3
With all targets defining CPU_RESOLVING_TYPE, refactor cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model) so that callers won't have to know internal resolving cpu type. Place it in exec.c so it could be called from both target independed vl.c and *-user/main.c. That allows us to stop abusing cpu type from MachineClass::default_cpu_type as resolver class in vl.c which were confusing part of cpu_parse_cpu_model(). Also with new parse_cpu_model(), the last users of cpu_init() in null-machine.c and bsd/linux-user targets could be switched to cpu_create() API and cpu_init() API will be removed by follow up patch. With no longer users left remove MachineState::cpu_model field, new code should use MachineState::cpu_type instead and leave cpu_model parsing to generic code in vl.c.
