* machine: Remove QEMUMachine indirection from MachineClassMarcel Apfelbaum2014-05-051-2/+2

* qmp: object-add: Validate class before creating objectEduardo Habkost2014-04-251-7/+14
| | | | | | | | | | | | | | | | | | | | | | | Currently it is very easy to crash QEMU by issuing an object-add command using an abstract class or a class that doesn't support TYPE_USER_CREATABLE as parameter. Example: with the following QMP command: (QEMU) object-add qom-type=cpu id=foo QEMU aborts at: ERROR:qom/object.c:335:object_initialize_with_type: assertion failed: (type->abstract == false) This patch moves the check for TYPE_USER_CREATABLE before object_new(), and adds a check to prevent the code from trying to instantiate abstract classes.

| | | | | | | | | | In order to allow attaching machine options to a machine instance, current_machine is converted into MachineState.

* add optional 2nd stage initialization to -object/object-add commandsIgor Mammedov2014-01-281-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | Introduces USER_CREATABLE interface that must be implemented by objects which are designed to created with -object CLI option or object-add QMP command. Interface provides an ability to do an optional second stage initialization of the object created with -object/object-add commands. By providing complete() callback, which is called after the object properties were set. It allows to: * prevents misusing of -object/object-add by filtering out objects that are not designed for it. * generalize second stage backend initialization instead of adding custom APIs to perform it * early error detection of backend initialization at -object/ object-add time rather than through a proxy DEVICE object that tries to use backend.

* build: replace weak symbols with a static libraryPaolo Bonzini2012-11-181-9/+0Star
| | | | | | | | | | | | | | | | | | | | | | Weak symbols were a nice idea, but they turned out not to be a good one. Toolchain support is just too sparse, in particular llvm-gcc is totally broken. This patch uses a surprisingly low-tech approach: a static library. Symbols in a static library are always overridden by symbols in an object file. Furthermore, if you place each function in a separate source file, object files for unused functions will not be taken in. This means that each function can use all the dependencies that it needs (especially QAPI stuff such as error_setg). Thus, all stubs are placed in separate object files and put together in a static library. The library then is linked to all programs.

This is bad because the actual behavior is not predictable; it is racy with respect to the start of the incoming migration. That's because incoming migration is blocking, and thus will delay the processing of stop/cont until the end of the migration. In addition, there's nothing that really prevents the user from typing the block device's passwords before incoming migration is done, so returning the DeviceEncrypted error is also helpful in the QMP case. Both things can be fixed by just toggling the autostart variable when stop/cont are called in INMIGRATE state. Note that libvirt is currently working around the race by looping if the MigrationExpected answer is returned. After this patch, the command will return right away without ever raising an error.

| | | | | | | | | | | | This command attempts to map to the behavior of -cpu ?. Unfortunately, the output of this command differs wildly across targets.

* runstate: introduce suspended stateLuiz Capitulino2012-05-081-0/+2
| | | | | | | | | | | | | | | | | | QEMU enters in this state when the guest suspends to ram (S3). This is important so that HMP users and QMP clients can know that the guest is suspended. QMP also has an event for this, but events are not reliable and are limited (ie. a client can connect to QEMU after the event has been emitted). Having a different state for S3 brings a new issue, though. Every device that doesn't run when the VM is stopped but wants to run when the VM is suspended has to check for RUN_STATE_SUSPENDED explicitly. This is the case for the keyboard and mouse devices, for example. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com>

This will enable search queries like, "any type that implements the BlockDevice interface" which would allow management tools to present available block devices without having to hard code device names. Since an object can implement multiple interfaces, one device could act both as a BlockDevice and a NetworkDevice. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | There are three important remarks in relation to the non-qapi command: 1. This commit also fixes the behavior of the 'query-vnc' and 'info vnc' commands to return an error when qemu is built without VNC support (ie. --disable-vnc). The non-qapi command would return the OK response in QMP and no response in HMP 2. The qapi version explicitly marks the fields 'host', 'family', 'service' and 'auth' as optional. Their are not documented as optional in the non-qapi command doc, but they would not be returned if vnc support is disabled. The qapi version maintains the same semantics, but documents those fields correctly 3. The 'clients' field, which is a list, is marked as optional but is always returned. If there are no clients connected an empty list is returned. This is not the Right Way to this in the qapi but it's how the non-qapi command used to work Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
