[Engine-devel] Serial Execution of Async Tasks

Hi guys, As you may know the engine currently has the ability to fire an SPM task, and be asynchronously be "woken-up" when it ends. This is great, but we found the for the Live Storage Migration feature we need something a bit complex - the ability to have a series of async tasks in a single control flow. Here's my initial design for this, your comments and criticism would be welcome: http://wiki.ovirt.org/wiki/Features/Serial_Execution_of_Asynchronous_Task... -Allon
