2012-03-19Introduce "xen-save-devices-state"Stefano Stabellini1-0/+19
- add an "is_ram" flag to SaveStateEntry; - register_savevm_live sets is_ram for live_savevm devices; - introduce a "xen-save-devices-state" QAPI command that can be used to save the state of all devices, but not the RAM or the block devices of the VM. Changes in v8: - rename save-devices-state to xen-save-devices-state. Changes in v7: - rename save_devices to save-devices-state. Changes in v6: - remove the is_ram parameter from register_savevm_live and sets is_ram if the device is a live_savevm device; - introduce save_devices as a QAPI command, write a better description for it; - fix CODING_STYLE; - introduce a new doc to explain the save format used by save_devices.

2012-03-15qapi: Convert migrateLuiz Capitulino1-0/+21
The migrate command is one of those commands where HMP and QMP completely mix up together. This made the conversion to the QAPI (which separates the command into QMP and HMP parts) a bit difficult. The first important change to be noticed is that this commit completes the removal of the Monitor object from migration code, started by the previous commit. Another important and tricky change is about supporting the non-detached mode. That is, if the user doesn't pass '-d' the migrate command will lock the monitor and will only release it when migration is finished. To support this in the new HMP command (hmp_migrate()), it is necessary to create a timer which runs every second and checks if the migration is still active. If it is, the timer callback will re-schedule itself to run one second in the future. If the migration has already finished, the monitor lock is released and the user can use it normally. All these changes should be transparent to the user. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2012-03-12qmp: convert blockdev-snapshot-sync to a wrapper around transactionsPaolo Bonzini1-7/+8
Simplify the blockdev-snapshot-sync code and gain failsafe operation by turning it into a wrapper around the new transaction command. A new option is also added matching "mode". Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-02-29qapi: Introduce blockdev-group-snapshot-sync commandJeff Cody1-0/+38
This is a QAPI/QMP only command to take a snapshot of a group of devices. This is similar to the blockdev-snapshot-sync command, except blockdev-group-snapshot-sync accepts a list devices, filenames, and formats. It is attempted to keep the snapshot of the group atomic; if the creation or open of any of the new snapshots fails, then all of the new snapshots are abandoned, and the name of the snapshot image that failed is returned. The failure case should not interrupt any operations. Rather than use bdrv_close() along with a subsequent bdrv_open() to perform the pivot, the original image is never closed and the new image is placed 'in front' of the original image via manipulation of the BlockDriverState fields. Thus, once the new snapshot image has been successfully created, there are no more failure points before pivoting to the new snapshot. This allows the group of disks to remain consistent with each other, even across snapshot failures.

2012-02-03qom: move properties from qdev to objectAnthony Liguori1-11/+11
This is mostly code movement although not entirely. This makes properties part of the Object base class which means that we can now start using Object in a meaningful way outside of qdev. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-03qom: add new command to search for typesAnthony Liguori1-0/+33
This adds a command that allows searching for types that implement a property. This allows you to do things like search for all available PCIDevices. In the future, we'll also have a standard interface for things with a BlockDriverState property that a PCIDevice could implement. 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>

2011-12-06qapi: Convert blockdev_snapshot_syncLuiz Capitulino1-0/+29
Unfortunately, this conversion required an additional change. In the old QMP command, the 'snapshot-file' argument is specified as optional. The idea is to take the snapshot internally if 'snapshot-file' is not passed. However, internal snapshots are not supported yet so the command returns a MissingParamater error if 'snapshot-file' is not passed. Which makes the argument actually required and will cause compatibility breakage if we change that in the future. To fix this the QAPI converted blockdev_snapshot_sync command makes the 'snapshot-file' argument required. Again, in practice it's actually required, so this is not incompatible. If we do implement internal snapshots someday, we'll need a new argument for it. Note that this discussion doesn't affect HMP. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

Please, note that some of the code supporting memory statistics is still around (eg. virtio_balloon_receive_stats() and reset_stats()). Also, the qmp_query_balloon() function is synchronous and thus doesn't make any use of the (not fully working) monitor's asynchronous command support (the old non-qapi implementation did).

2011-10-27qapi: Convert query-vncLuiz Capitulino1-0/+81
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>
