Example 6 with ExecutionContext

use of org.ovirt.engine.core.bll.job.ExecutionContext in project ovirt-engine by oVirt.

the class RunVmCommand method createContextForRunStatelessVm.

    if (step == null) {
        return cloneContextAndDetachFromParent();
    }

    // at this is a new instance of the command is used
    // (comparing with the execution state) so all information on the job and steps should be retrieved.
    Job job = jobRepository.getJobWithSteps(step.getJobId());

    // the "beginning step" of the child command.
