2011-07-21guest agent: add guest agent RPCs/commandsMichael Roth7-3/+768
This adds the initial set of QMP/QAPI commands provided by the guest agent: guest-sync guest-ping guest-info guest-shutdown guest-file-open guest-file-read guest-file-write guest-file-seek guest-file-flush guest-file-close guest-fsfreeze-freeze guest-fsfreeze-thaw guest-fsfreeze-status The input/output specification for these commands are documented in the schema.

2011-07-21guest agent: qemu-ga daemonMichael Roth4-3/+660
This is the actual guest daemon, it listens for requests over a virtio-serial/isa-serial/unix socket channel and routes them through to dispatch routines, and writes the results back to the channel in a manner similar to QMP. A shorthand invocation: qemu-ga -d Is equivalent to: qemu-ga -m virtio-serial -p /dev/virtio-ports/org.qemu.guest_agent.0 \ -f /var/run/qemu-ga.pid -d Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@gmail.com>

2011-07-21qapi: add qapi-commands.py code generatorMichael Roth1-0/+385
This is the code generator for qapi command marshaling/dispatch. Currently only generators for synchronous qapi/qmp functions are supported. This script generates the following files: $(prefix)qmp-marshal.c: command marshal/dispatch functions for each QMP command defined in the schema. Functions generated by qapi-visit.py are used to convert qobjects recieved from the wire into function parameters, and uses the same visiter functions to convert native C return values to qobjects from transmission back over the wire. $(prefix)qmp-commands.h: Function prototypes for the QMP commands specified in the schema. $(prefix) is used in the same manner as with qapi-types.py Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@gmail.com>
2011-07-21qapi: add qapi-visit.py code generatorMichael Roth1-0/+246
This is the code generator for qapi visiter functions used to marshal/unmarshal/dealloc qapi types. It generates the following 2 files: $(prefix)qapi-visit.c: visiter function for a particular c type, used to automagically convert qobjects into the corresponding C type and vice-versa, and well as for deallocation memory for an existing C type $(prefix)qapi-visit.h: declarations for previously mentioned visiter functions $(prefix) is used as decribed for qapi-types.py Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@gmail.com>
2011-07-21qapi: add qapi-types.py code generatorMichael Roth1-0/+270
This is the code generator for qapi types. It will generation the following files: $(prefix)qapi-types.h - C types corresponding to types defined in the schema you pass in $(prefix)qapi-types.c - Cleanup functions for the above C types The $(prefix) is used to as a namespace to keep the generated code from one schema/code-generation separated from others so code and be generated from multiple schemas with clobbering previously created code.

2011-07-21qapi: add QMP dispatch functionsMichael Roth3-1/+127
Given an object recieved via QMP, this code uses the dispatch table provided by qmp_registry.c to call the corresponding marshalling/dispatch function and format return values/errors for delivery to the QMP. Currently only synchronous QMP functions are supported, but this will also be used for async QMP functions and QMP guest proxy dispatch as well.

2011-07-21qapi: add QMP output visitorMichael Roth3-1/+268
Type of Visiter class that serves as the inverse of the input visitor: it takes a series of native C types and uses their values to construct a corresponding QObject. The command marshaling/dispatcher functions will use this to convert the output of QMP functions into a QObject that can be sent over the wire.

2011-07-21qapi: add QMP input visitorMichael Roth4-1/+332
A type of Visiter class that is used to walk a qobject's structure and assign each entry to the corresponding native C type. Command marshaling function will use this to pull out QMP command parameters recieved over the wire and pass them as native arguments to the corresponding C functions.

2011-07-21qapi: add QAPI visitor coreMichael Roth5-0/+221
Base definitions/includes for Visiter interface used by generated visiter/marshalling code. Includes a GenericList type. Our lists require an embedded element. Since these types are generated, if you want to use them in a different type of data structure, there's no easy way to add another embedded element. The solution is to have non-embedded lists and that what this is. Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@gmail.com>

2011-07-21Add hard build dependency on glibAnthony Liguori4-0/+17
GLib is an extremely common library that has a portable thread implementation along with tons of other goodies. GLib and GObject have a fantastic amount of infrastructure we can leverage in QEMU including an object oriented programming infrastructure. Short term, it has a very nice thread pool implementation that we could leverage in something like virtio-9p. It also has a test harness implementation that this series will use.

2011-07-21Error: Fix build when qemu-common.h is not includedLuiz Capitulino1-0/+1
Commit e4ea5e2d0e0e4c5188ab45b66f3195062ae059dc added the use of the macro GCC_FMT_ATTR to error.h, however compiler.h is not included by error.h This will cause a build error when files including error.h don't include qemu-common.h (or compiler.h). Not an issue today because the only file including it is json-parser.h and it does include qemu-common.h, but let's get it fixed. Signed-off-by: Luiz Capitulino <lcapitulino@gmail.com>
2011-07-21Introduce compiler.h header fileLuiz Capitulino2-24/+35
This moves compiler related macros from qemu-common.h to compiler.h. The reason for this change is that there are simple header files that depend only on the compiler macros, so including qemu-common.h is overkill. Besides, qemu-common.h is bloated and will benefit from some splitting. Please, also note that the QEMU_BUILD_BUG_ON() macro is being fixed to not use double underscores as a prefix and the license text was added by Vassili Karpov (malc), who is one of the authors of the new file.

2011-07-21QMP: add snapshot-blkdev-sync commandJes Sorensen3-3/+37

In the future async commands and or a break down of the functionality into multiple commands might be added. Also change the 'snapshot_file' argument to 'snapshot-file' in the human monitor, so that it matches QMP.

2011-07-19qcow2: Use Qcow2Cache in writeback mode during loadvm/savevmKevin Wolf3-11/+41
In snapshotting there is no guest involved, so we can safely use a writeback mode and do the flushes in the right place (i.e. at the very end). This improves the time that creating/restoring an internal snapshot takes with an image in writethrough mode. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-07-19block: add bdrv_get_allocated_file_size() operationFam Zheng7-30/+96
qemu-img.c wants to count allocated file size of image. Previously it counts a single bs->file by 'stat' or Window API. As VMDK introduces multiple file support, the operation becomes format specific with platform specific meanwhile. The functions are moved to block/raw-{posix,win32}.c and qemu-img.c calls bdrv_get_allocated_file_size to count the bs. And also added VMDK code to count his own extents.
