2018-02-26s390x/cpu: expose the guest crash informationChristian Borntraeger1-2/+9
This patch is the s390 implementation of guest crash information, similar to commit d187e08dc4 ("i386/cpu: add crash-information QOM property") and the related commits. We will detect several crash reasons, with the "disabled wait" being the most important one, since this is used by all s390 guests as a "panic like" notification. Demonstrate these ways with examples as follows. 1. crash-information QOM property; Run qemu with -qmp unix:qmp-sock,server, then use utility "qmp-shell" to execute "qom-get" command, and might get the result like, (QEMU) (QEMU) qom-get path=/machine/unattached/device[0] \ property=crash-information {"return": {"core": 0, "reason": "disabled-wait", "psw-mask": 562956395872256, \ "type": "s390", "psw-addr": 1102832}} 2. GUEST_PANICKED event reporting; Run qemu with a socket option, and telnet or nc to that, -chardev socket,id=qmp,port=4444,host=localhost,server \ -mon chardev=qmp,mode=control,pretty=on \ Negotiating the mode by { "execute": "qmp_capabilities" }, and the crash information will be reported on a guest crash event like, { "timestamp": { "seconds": 1518004739, "microseconds": 552563 }, "event": "GUEST_PANICKED", "data": { "action": "pause", "info": { "core": 0, "psw-addr": 1102832, "reason": "disabled-wait", "psw-mask": 562956395872256, "type": "s390" } } } 3. log; Run qemu with the parameters: -D <logfile> -d guest_errors, to specify the logfile and log item. The results might be, Guest crashed on cpu 0: disabled-wait PSW: 0x0002000180000000 0x000000000010d3f0 Co-authored-by: Jing Liu <liujbjl@linux.vnet.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Message-Id: <20180209122543.25755-1-borntraeger@de.ibm.com> Reviewed-by: Eric Blake <eblake@redhat.com> [CH: tweaked qapi comment] Signed-off-by: Cornelia Huck <cohuck@redhat.com>

2018-02-15vl: pause vcpus before stopping iothreadsStefan Hajnoczi1-1/+9
Commit dce8921b2baaf95974af8176406881872067adfa ("iothread: Stop threads before main() quits") introduced iothread_stop_all() to avoid the following virtio-scsi assertion failure: assert(blk_get_aio_context(d->conf.blk) == s->ctx); Back then the assertion failed because when bdrv_close_all() made d->conf.blk NULL, blk_get_aio_context() returned the global AioContext instead of s->ctx. The same assertion can still fail today when vcpus submit new I/O requests after iothread_stop_all() has moved the BDS to the global AioContext. This patch hardens the iothread_stop_all() approach by pausing vcpus before calling iothread_stop_all(). Note that the assertion failure is a race condition. It is not possible to reproduce it reliably.

2018-01-26usb: Remove legacy -usbdevice options (host, serial, disk and net)Thomas Huth1-15/+0
The option have been marked as deprecated since QEMU 2.10, and so far nobody complained that the host, serial, disk and net options are urgently required anymore. So let's now get rid at least of this legacy pile, to simplify the usb code quite a bit. This patch removes the usbdevices host, serial, disk and net. These devices use their own complicated parameter parsing mechanisms, so they are just ugly to maintain, without real benefit for the users (the users can use the corresponding "-device" parameters instead which have the same complexity as the "-usbdevice" devices here). Note that the other rather simple -usbdevice options (mouse, tablet, etc.) are not removed yet (the code is really simple here, so it does not hurt much to keep it), as well as the two devices "braille" and "bt" which are easier to use with -usbdevice than with -device.

2018-01-19possible_cpus: add CPUArchId::type fieldIgor Mammedov1-2/+1
Remove dependency of possible_cpus on 1st CPU instance, which decouples configuration data from CPU instances that are created using that data. Also later it would be used for enabling early cpu to numa node configuration at runtime qmp_query_hotpluggable_cpus() should provide a list of available cpu slots at early stage, before machine_init() is called and the 1st cpu is created, so that mgmt might be able to call it and use output to set numa mapping. Use MachineClass::possible_cpu_arch_ids() callback to set cpu type info, along with the rest of possible cpu properties, to let machine define which cpu type* will be used. * for SPAPR it will be a spapr core type and for ARM/s390x/x86 a respective descendant of CPUClass. Move parse_numa_opts() in vl.c after cpu_model is parsed into cpu_type so that possible_cpu_arch_ids() would know which cpu_type to use during layout initialization.

2017-11-16NUMA: Enable adding NUMA node implicitlyDou Liyang1-2/+1
Linux and Windows need ACPI SRAT table to make memory hotplug work properly, however currently QEMU doesn't create SRAT table if numa options aren't present on CLI. Which breaks both linux and windows guests in certain conditions: * Windows: won't enable memory hotplug without SRAT table at all * Linux: if QEMU is started with initial memory all below 4Gb and no SRAT table present, guest kernel will use nommu DMA ops, which breaks 32bit hw drivers when memory is hotplugged and guest tries to use it with that drivers. Fix above issues by automatically creating a numa node when QEMU is started with memory hotplug enabled but without '-numa' options on CLI. (PS: auto-create numa node only for new machine types so not to break migration). Which would provide SRAT table to guests without explicit -numa options on CLI and would allow: * Windows: to enable memory hotplug * Linux: switch to SWIOTLB DMA ops, to bounce DMA transfers to 32bit allocated buffers that legacy drivers/hw can handle.

2017-11-13hw: add .min_cpus and .default_cpus fields to machine_classEmilio G. Cota1-3/+18
max_cpus needs to be an upper bound on the number of vCPUs initialized; otherwise TCG region initialization breaks. Some boards initialize a hard-coded number of vCPUs, which is not captured by the global max_cpus and therefore breaks TCG initialization. Fix it by adding the .min_cpus field to machine_class. This commit also changes some user-facing behaviour: we now die if -smp is below this hard-coded vCPU minimum instead of silently ignoring the passed -smp value (sometimes announcing this by printing a warning). However, the introduction of .default_cpus lessens the likelihood that users will notice this: if -smp isn't set, we now assign the value in .default_cpus to both smp_cpus and max_cpus. IOW, if a user does not set -smp, they always get a correct number of vCPUs. This change fixes 3468b59 ("tcg: enable multiple TCG contexts in softmmu", 2017-10-24), which broke TCG initialization for some ARM boards.

Add a firmware path config option to configure. Multiple directories are accepted, with the usual colon as separator. Default value is ${prefix}/share/qemu-firmware. The path is searched in addition to the current search path (typically ${prefix}/share/qemu). This prepares qemu for the planned split of the prebuilt firmware blobs into a separate project. Distributions can also use this to get rid of the firmware symlink farm and add -- for example -- /usr/share/seabios to the firmware path instead.

2017-09-22scsi, file-posix: add support for persistent reservation managementPaolo Bonzini1-1/+2
It is a common requirement for virtual machine to send persistent reservations, but this currently requires either running QEMU with CAP_SYS_RAWIO, or using out-of-tree patches that let an unprivileged QEMU bypass Linux's filter on SG_IO commands. As an alternative mechanism, the next patches will introduce a privileged helper to run persistent reservation commands without expanding QEMU's attack surface unnecessarily. The helper is invoked through a "pr-manager" QOM object, to which file-posix.c passes SG_IO requests for PERSISTENT RESERVE OUT and PERSISTENT RESERVE IN commands. For example: $ qemu-system-x86_64 -device virtio-scsi \ -object pr-manager-helper,id=helper0,path=/var/run/qemu-pr-helper.sock -drive if=none,id=hd,driver=raw,file.filename=/dev/sdb,file.pr-manager=helper0 -device scsi-block,drive=hd or: $ qemu-system-x86_64 -device virtio-scsi \ -object pr-manager-helper,id=helper0,path=/var/run/qemu-pr-helper.sock -blockdev node-name=hd,driver=raw,file.driver=host_device,file.filename=/dev/sdb,file.pr-manager=helper0 -device scsi-block,drive=hd Multiple pr-manager implementations are conceivable and possible, though only one is implemented right now. For example, a pr-manager could: - talk directly to the multipath daemon from a privileged QEMU (i.e. QEMU links to libmpathpersist); this makes reservation work properly with multipath, but still requires CAP_SYS_RAWIO - use the Linux IOC_PR_* ioctls (they require CAP_SYS_ADMIN though) - more interestingly, implement reservations directly in QEMU through file system locks or a shared database (e.g. sqlite) Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2017-09-19vl.c: convert cpu_model to cpu type and set of global properties before ↵Igor Mammedov1-0/+10
machine_init() All machines that support user specified cpu_model either call cpu_generic_init() or cpu_class_by_name()/CPUClass::parse_features to parse feature string and to get CPU type to create. Which leads to code duplication and hard-codding default CPU model within machine_foo_init() code. Which makes it impossible to get CPU type before machine_init() is run. So instead of setting default CPUs models and doing parsing in target specific machine_foo_init() in various ways, provide a generic data driven cpu_model parsing before machine_init() is called. in follow up per target patches, it will allow to: * define default CPU type in consistent/generic manner per machine type and drop custom code that fallbacks to default if cpu_model is NULL * drop custom features parsing in targets and do it in centralized way. * for cases of cpu_generic_init(TYPE_BASE/DEFAULT_CPU, "some_cpu") replace it with cpu_create(machine->cpu_type) || cpu_create(TYPE_FOO) depending if CPU type is user settable or not. not doing useless parsing and clearly documenting where CPU model is user settable or fixed one. Patch allows machine subclasses to define default CPU type per machine class at class_init() time and if that is set generic code will parse cpu_model into a MachineState::cpu_type which will be used to create CPUs for that machine instance and allows gradual per board conversion.
