2013-07-15net: add support of mac-programming over macvtap in QEMU sideAmos Kong1-0/+17
Currently macvtap based macvlan device is working in promiscuous mode, we want to implement mac-programming over macvtap through Libvirt for better performance. Design: QEMU notifies Libvirt when rx-filter config is changed in guest, then Libvirt query the rx-filter information by a monitor command, and sync the change to macvtap device. Related rx-filter config of the nic contains main mac, rx-mode items and vlan table. This patch adds a QMP event to notify management of rx-filter change, and adds a monitor command for management to query rx-filter information. Test: If we repeatedly add/remove vlan, and change macaddr of vlan interfaces in guest by a loop script. Result: The events will flood the QMP client(management), management takes too much resource to process the events. Event_throttle API (set rate to 1 ms) can avoid the events to flood QMP client, but it could cause an unexpected delay (~1ms), guests guests normally expect rx-filter updates immediately. So we use a flag for each nic to avoid events flooding, the event is emitted once until the query command is executed. The flag implementation could not introduce unexpected delay. There maybe exist an uncontrollable delay if we let Libvirt do the real change, guests normally expect rx-filter updates immediately. But it's another separate issue, we can investigate it when the work in Libvirt side is done. Michael S. Tsirkin: tweaked to enable events on start Michael S.

2013-05-15qmp: fix handling of cmd with Equals in qmp-shellZhangleiqiang1-0/+2
qmp: fix handling of cmd with equal mark in qmp-shell qmp-shell splits the argument and value of input command by equal mark("="). But there are commands whose values include equal mark themselves, and the json built by qmp-shell will not correct. For example, when using NBD as the target of block-backup command, the input "block-backup target=nbd+unix:///drive0?socket=/tmp/nbd.sock" will fail, because the json built will be as follows: { "execute":"block-backup", "arguments":{"target":"nbd+unix:///drive0?socket"} } Fix it by joining the sections split by equal mark excluding the first section in __build_cmd function when the length of sections is larger than two.

2012-09-28block: introduce block job errorPaolo Bonzini1-0/+22
The following behaviors are possible: 'report': The behavior is the same as in 1.1. An I/O error, respectively during a read or a write, will complete the job immediately with an error code. 'ignore': An I/O error, respectively during a read or a write, will be ignored. For streaming, the job will complete with an error and the backing file will be left in place. For mirroring, the sector will be marked again as dirty and re-examined later. 'stop': The job will be paused and the job iostatus will be set to failed or nospace, while the VM will keep running. This can only be specified if the block device has rerror=stop and werror=stop or enospc. 'enospc': Behaves as 'stop' for ENOSPC errors, 'report' for others. In all cases, even for 'report', the I/O error is reported as a QMP event BLOCK_JOB_ERROR, with the same arguments as BLOCK_IO_ERROR. It is possible that while stopping the VM a BLOCK_IO_ERROR event will be reported and will clobber the event from BLOCK_JOB_ERROR, or vice versa. This is not really avoidable since stopping the VM completes all pending I/O requests. In fact, it is already possible now that a series of BLOCK_IO_ERROR events are reported with rerror=stop, because vm_stop calls bdrv_drain_all and this can generate further errors.

If the active layer is passed in as top, then an error will be returned. Once merging down the active layer is supported, the 'top' argument may become optional, and default to the active layer.

2012-09-26Add qemu-ga-client scriptRyota Ozaki1-0/+299
This is an easy-to-use QEMU guest agent client written in Python. It simply provides commands to call guest agent functions like ping, fsfreeze and shutdown. Additionally, it provides extra useful commands, e.g, cat, ifconfig and reboot, by using guet agent functions. Examples: $ export QGA_CLIENT_ADDRESS=/tmp/qga.sock $ qemu-ga-client ping $ qemu-ga-client cat /etc/resolv.conf # Generated by NetworkManager nameserver 10.0.2.3 $ qemu-ga-client fsfreeze status thawed $ qemu-ga-client fsfreeze freeze 2 filesystems frozen The script communicates with a guest agent by means of qmp.QEMUMonitorProtocol. Every commands are called with timeout (3 sec.) to avoid blocking. The script always calls sync command prior to issuing an actual command (except for ping which doesn't need sync).

2012-08-13qmp: add SUSPEND_DISK eventLuiz Capitulino1-0/+14
Emitted when the guest makes a request to enter S4 state. There are three possible ways of having this event, as described here: http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html I've decided to add a new event and make it indepedent of SHUTDOWN. This means that the SHUTDOWN event will eventually follow the SUSPEND_DISK event. I've choosen this way because of two reasons: 1. Having an indepedent event makes it possible to query for its existence by using query-events 2. In the future, we may allow the user to change what QEMU should do as a result of the guest entering S4. So it's a good idea to keep both events separated Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2012-08-13qmp: emit the WAKEUP event when the guest is put to runLuiz Capitulino1-0/+13
Today, the WAKEUP event is emitted when a wakeup _request_ is made. This could be the system_wakeup command, for example. A better semantic would be to emit the event when the guest is already running, as that's what matters in the end. This commit does that change. In theory, this could break compatibility. In practice, it shouldn't happen though, as clients shouldn't rely on timing characteristics of the events. That is, a client relying that the guest is not running when the event arrives may break if the event arrives after the guest is already running. This commit also adds the missing documentation for the WAKEUP event. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com>
2012-08-13qmp: switch to the new error format on the wireLuiz Capitulino1-7/+3
IMPORTANT: this BREAKS QMP's compatibility for the error response. This commit changes QMP's wire protocol to make use of the simpler error format introduced by previous commits. There are two important (and mostly incompatible) changes: 1. Almost all error classes have been replaced by GenericError. The only classes that are still supported for compatibility with libvirt are: CommandNotFound, DeviceNotActive, KVMMissingCap, DeviceNotFound and MigrationExpected 2. The 'data' field of the error dictionary is gone As an example, an error response like: { "error": { "class": "DeviceNotRemovable", "data": { "device": "virtio0" }, "desc": "Device 'virtio0' is not removable" } } Will now be emitted as: { "error": { "class": "GenericError", "desc": "Device 'virtio0' is not removable" } } Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>
2012-06-15Add event notification for guest balloon changesDaniel P. Berrange1-0/+18
After setting a balloon target value, applications have to continually poll 'query-balloon' to determine whether the guest has reacted to this request. The virtio-balloon backend knows exactly when the guest has reacted though, and thus it is possible to emit a JSON event to tell the mgmt application whenever the guest balloon changes. This introduces a new 'qemu_balloon_changed()' API which is to be called by balloon driver backends, whenever they have a change in balloon value. This takes the 'actual' balloon value, as would be found in the BalloonInfo struct. The qemu_balloon_change API emits a JSON monitor event which looks like: {"timestamp": {"seconds": 1337162462, "microseconds": 814521}, "event": "BALLOON_CHANGE", "data": {"actual": 944766976}} * balloon.c, balloon.h: Introduce qemu_balloon_changed() for emitting balloon change events on the monitor * hw/virtio-balloon.c: Invoke qemu_balloon_changed() whenever the guest changes the balloon actual value * monitor.c, monitor.h: Define QEVENT_BALLOON_CHANGE Signed-off-by: Daniel P.

2010-07-01QMP: Teach basic capability negotiation to python exampleJan Kiszka2-0/+2

2010-06-13monitor/QMP: Drop info hpet / query-hpetJan Kiszka1-1/+1
This command was of minimal use before, now it is useless as the hpet become a qdev device and is thus easily discoverable. We should definitely not set query-hpet in QMP's stone, and there is also no good reason to keep it for the interactive monitor.

2010-06-01QMP: Introduce commands documentationJan Kiszka1-2/+3
One of the most important missing feature in QMP today is its supported commands documentation. The plan is to make it part of self-description support, however self-description is a big task we have been postponing for a long time now and still don't know when it's going to be done. In order not to compromise QMP adoption and make users' life easier, this commit adds a simple text documentation which fully describes all QMP supported commands. This is not ideal for a number of reasons (harder to maintain, text-only, etc) but does improve the current situation. To avoid at least divering from the user monitor help and texi snippets, QMP bits are also maintained inside qemu-monitor.hx, and hxtool is extended to generate a single text file from them.

2010-05-03QMP: Introduce RESUME eventLuiz Capitulino1-0/+12
It's emitted when the Virtual Machine resumes execution. We currently have the STOP event but don't have the matching RESUME one, this means that clients are notified when the VM is stopped but don't get anything when it resumes. Let's fix that as it's already causing some trouble to libvirt. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
