Paolo Bonzini	a66a2a3683	block: introduce BLOCK_JOB_READY event Even for jobs that need to be manually completed, management may want to take care itself of the completion, not requiring the user to issue a command to terminate the job. In this case we want to avoid that they poll us continuously, waiting for completion to become available. Thus, add a new event that signals the phase switch and the availability of the block-job-complete command.

Paolo Bonzini	aeae883baf	block: add block-job-complete While streaming can be dropped as soon as it progressed through the whole image, mirroring needs to be completed manually for two reasons: 1) so that management knows exactly when the VM switches to the target; 2) because for other use cases such as replication, we may leave the operation running for the whole life of the virtual machine. Add a new block job command that manually completes background operations. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>	14 years ago

Paolo Bonzini	32c81a4a6e	block: introduce block job error 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.

Paolo Bonzini	8acc72a4d2	block: add support for job pause/resume Job pausing reuses the existing support for cancellable sleeps. A pause happens at the next sleeping point and lasts until the coroutine is re-entered explicitly. Cancellation was already doing a forced resume, so implement it explicitly in terms of resume. Paused jobs cannot be canceled without first resuming them. This ensures that I/O errors are never missed by management.

Paolo Bonzini	8d65883fff	qmp: add 'busy' member to BlockJobInfo Because pausing a job is asynchronous, we need to know whether it has completed. This is described by the "busy" field of BlockJob; copy it to BlockJobInfo.
