* display migration: restore destination stateYonit Halperin2012-08-271-74/+148
| | | | | | Restoring display channel from migration data. Not notifying client about changes that are artifacts of loading the vm. Remove legacy migration code.
* display migration: marshall migration dataYonit Halperin2012-08-271-6/+46
|
* display & cursor migration: send SPICE_MSG_MIGRATEYonit Halperin2012-08-271-52/+3
|
* migration_protocol: add display channel migration dataYonit Halperin2012-08-271-0/+73
|
* inputs channel: use the default red_channel behaviour for client_cbs.migrateYonit Halperin2012-08-271-7/+0
| | | | The default callback sends SPICE_MSG_MIGRATE to the client.
* inputs channel: fix using spice messages enums as pipe items typeYonit Halperin2012-08-271-13/+11
| | | | | | A channel pipe item type must start from PIPE_ITEM_TYPE_CHANNEL_BASE. SPICE_MSG_MIGRATE value eq. PIPE_ITEM_TYPE_SET_ACK. Setting a pipe item type to SPICE_MSG_MIGRATE, leads to red_channel handling PIPE_ITEM_TYPE_SET_ACK.
* char_device: don't connect a migrated client if the state of the device ↵Yonit Halperin2012-08-275-38/+72
| | | | | | | | might have changed since it was created If reading/writing from the device have occured before migration data has arrived, the migration data might no longer be relvant, and we disconnect the client.
* main: restore state from migration dataYonit Halperin2012-08-274-53/+168
| | | | Also removed old migration leftovers.
* main: send migration dataYonit Halperin2012-08-273-23/+95
| | | | | Also removed some unused definitions from reds that used to belong to old agent and migration code.
* main: send MSG_MIGRATE upon vm migration completionYonit Halperin2012-08-274-1/+56
| | | | | | | | | Before sending the above msg, if there is a pending partial msg that has been read from the agent, we send it to the client. The alternative was to keep the msg as part of the migration data, and then to send it to the destination server via the client and to wait there for the msg chunk completion, before sending it to the client. Of course, the latter is less efficient.
* reds: s/HADER/HEADERYonit Halperin2012-08-271-5/+5

* migration_protocol: add migration data for the main channel (mainly for the ↵Yonit Halperin2012-08-271-0/+33
| | | | agent)
* main_channel: fix using spice messages enums as pipe items typeYonit Halperin2012-08-272-107/+147
| | | | | | | | | A channel pipe item type must start from PIPE_ITEM_TYPE_CHANNEL_BASE. SPICE_MSG_MIGRATE value eq. PIPE_ITEM_TYPE_SET_ACK. Setting a pipe item type to SPICE_MSG_MIGRATE, leads to red_channel handling PIPE_ITEM_TYPE_SET_ACK. Also removed sending SPICE_MSG_MIGRATE. It will be handled in the next patch.
* red_channel: introduce PIPE_ITEM_TYPE_EMPTY_MSGYonit Halperin2012-08-272-0/+43
| | | | The pipe item is used for sending messages that don't have body.
* smartcard: restore state after migration from migration dataYonit Halperin2012-08-271-7/+75

* smartcard migration: send migration dataYonit Halperin2012-08-271-5/+51
|
* migration_protocol: add migration data for smartcardYonit Halperin2012-08-271-0/+14
|
* smartcard: send MSG_MIGRATE upon vm migration completionYonit Halperin2012-08-271-5/+0
| | | | | The above is the default behaviour for red_channel_client, if client_cbs.migrate is not registered as part of red_channel_register_client_cbs
* smartcard: fix PIPE_ITEMs enum indexingYonit Halperin2012-08-271-1/+1
| | | | | The enum should start from PIPE_ITEM_TYPE_CHANNEL_BASE, otherwise, PIPE_ITEM_TYPE_ERROR is handled like PIPE_ITEM_TYPE_SET_ACK.
* smartcard: change the timing of attaching a client to SpiceCharDeviceStateYonit Halperin2012-08-271-45/+75
| | | | | | | | | Attach/detach a client to a SpiceCharDeviceState upon its connection/disconnection, instead of upon reader_add/remove messages. When the client is removed from a SpiceCharDeviceState, all the messages from this client are removed from the device write queue. This shouldn't happen when we only receive reader_remove and the client is still connected.
* spicevmc migration: restore migration dest state from migration dataYonit Halperin2012-08-271-2/+29
|
* spicevmc migration: send migration dataYonit Halperin2012-08-271-5/+55
|
* spicevmc: send MSG_MIGRATE upon vm migration completionYonit Halperin2012-08-271-6/+0
| | | | | The above is the default behaviour for red_channel_client, if client_cbs.migrate is not registered as part of red_channel_register_client_cbs
* migration_protocol: add migration data for spicevmcYonit Halperin2012-08-271-0/+11

* char device migration: don't read or write from/to the device while waiting ↵Yonit Halperin2012-08-275-14/+32
| | | | for migraion data
* char device migration: marshall migration dataYonit Halperin2012-08-272-0/+74
|
* char_device: variable token price for write buffersYonit Halperin2012-08-272-12/+29
| | | | | | | When restoring migration data, we also restore data that is addressed to the device, and that might have been originated from more than 1 message. When the write buffer that is assoicated with this data is released, we need to free all the relevant tokens.
* migration_protocol: add migration data for char devicesYonit Halperin2012-08-271-0/+20
|
* replace some migration related spice_error calls with info/warningYonit Halperin2012-08-271-2/+2
|
* seamless migration: migration completion on the destination sideYonit Halperin2012-08-278-25/+202
| | | | | | Tracking the channels that wait for migration data. If there is a new migration process pending, when all the channels have restored their state, we begin the new migration.
* red_channel: handle sending SPICE_MSG_MIGRATEYonit Halperin2012-08-277-21/+69
| | | | | | | The relevant code is common to all channels. The patch also contains a fix to the return value for handle_migrate_data callback: s/uint64_t/int
* red_channel: fix pipe item leakYonit Halperin2012-08-271-0/+1
|
* seamleass migration: manage post migration phase in the src sideYonit Halperin2012-08-271-13/+108
| | | | | | | | | | | In semi-seamless, SPICE_MSG_MAIN_MIGRATE_END is sent. In seamless, each channel migrates separately. The src waits till all the clients are disconnected (or a timeout), and then it notifies qemu that spice migration has completed. The patch doesn't include the per-channel logic for seamless migration (sending MSG_MIGRATE, MIGRATE_DATA, etc.).
* seamless migration: pre migration phase on the destination sideYonit Halperin2012-08-273-16/+85
| | | | | | | | | | - handle SPICE_MSGC_MAIN_MIGRATE_DST_DO_SEAMLESS - reply with SPICE_MSG_MAIN_MIGRATE_DST_SEAMLESS_ACK/NACK - prepare the channels for migration according to the migration type (semi/seamless) see spice-protocol for more details: commit 3838ad140a046c4ddf42fef58c9727ecfdc09f9f
* seamless migration: pre migration phase on the src sideYonit Halperin2012-08-274-27/+124
| | | | | | | | | | | | | | sending SPICE_MSG_MAIN_MIGRATE_BEGIN_SEAMLESS and handling SPICE_MSGC_MAIN_MIGRATE_CONNECTED_SEAMLESS The src side signals the client to establish a connection to the destination. In seamless migration, the client is also used to perform a sort of handshake with the destination, for verifying if seamless migration can be supported. see spice-protocol for more details: commit 3838ad140a046c4ddf42fef58c9727ecfdc09f9f
* seamless-migration: update spice-common submoduleYonit Halperin2012-08-273-17/+17
| | | | | | Also Update server and client according to the change of SpiceMsgMainMigrationBegin: it now holds all the fields inside SpiceMigrationDstInfo.
* seamless-migration: add migration_protocol.hYonit Halperin2012-08-272-0/+50
| | | | | | | The file will hold the declarations of the different migration data messages (depending on the channel), that will be passed from the src server to the dst server, via the client, using SPICE_MSG_MIGRATE_DATA.
* bump version to 0.11.2Yonit Halperin2012-08-273-2/+9
| | | | | | | New api entries: spice_server_vm_start spice_server_vm_stop spice_server_set_seamless_migration
* spice.h: add spice_server_set_seamless_migrationYonit Halperin2012-08-272-0/+11
| | | | | | | | | | This new call is used in order to identify whether qemu, or the management (e.g. libvirt), support seamless migration. If it is supported, qemu spice cmd-line configuration should have seamless-migration=on. In addition, we disable seamless migration support if multiple clients are allowed. Currently, only one client is supported.
* spice_server_vm_start/stop: notify red_dispatcher on vm start/stopYonit Halperin2012-08-274-2/+30
| | | | | | | Till now, red_worker was notfied about vm status changes via QXLWorker->start/stop (or spice_qxl_start/stop). Newer qemu, that supports calling spice_server_vm_start/stop, will call only these routines, and won't call QXLWorker->start/stop.
* spice.h: add entries for tracking vm stateYonit Halperin2012-08-272-1/+36
| | | | | | | | | When vm state changes (started/stopped), we notify all the attached SpiceCharDeviceStates about the change. This is mainly required for avoiding writing/reading to/from the device during the non-live stage of migration. spice version will be bumped in one of the following patches.
* reds: add tracking for char devicesYonit Halperin2012-08-273-0/+46
| | | | | | The list of attached char_devices will be used in the next patch for notifying each instance of SpiceCharDeviceState when the vm is started or stopped.
* agent: don't attempt to read from the device if it was releasedYonit Halperin2012-08-271-1/+3
| | | | | if vdi_port_read_buf_process failes, we detach the agent and also release the read buffer. We shouldn't try reading from the device afterwards.
* agent: reset client tokens when notifying on agent connectionYonit Halperin2012-08-273-7/+26
| | | | send SPICE_MSG_MAIN_AGENT_CONNECTED_TOKENS
* red_channel: add red_channel_test_remote_capYonit Halperin2012-08-272-0/+32
| | | | for checking if all the channel clients connected support the cap
* Add support for Composite command to the clientSøren Sandmann Pedersen2012-08-244-0/+22
| | | | | | All the real work is being done in spice-common, so this patch is just hooking up the virtual calls and adding the SPICE_DISPLAY_CAP_COMPOSITE capability.
* Add support for QXLComposite to spice serverSøren Sandmann Pedersen2012-08-244-2/+164
| | | | | | In red-parse-qxl.c add support for parsing QXLComposite into SpiceComposite. In red-worker.c add support for marshalling SpiceComposite onto the wire.
* Add support for LZ compression of A8 imagesSøren Sandmann Pedersen2012-08-244-10/+17
| | | | | | Graduality is irrelevant for A8 images, so instead of using RGB-ness as a short-cut, add a new macro BITMAP_FMT_HAS_GRADUALITY() that returns true for the existing RGB images, but false for A8.
* Update spice-commonMarc-André Lureau2012-08-091-0/+0
