Hi Jeronimo,

The StartCommands for the Virtual machine are executed sequentially by the
agent. This behavior is set as "executeInSequence" flag on the command
level.

You might look at the Command abstract class (StartCommand extends it) to
see how it works. But basically if this flag is set to true for the
command, it's been queued on per Agent(Host) basis.

-Alena.
