>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: Management Server
>    Affects Versions: 4.2.0

>             Fix For: 4.2.0
> When a user deploys multiple instances concurrently, the deployment of these VMs are
in fact queued up, so although CloudStack reports that all deployments have started to be
created, it would appear in reality that until the 1st instance is deployed, the second, third,
etc are queued and waiting to be executed. 
> CS should be able to support parallel VM deployment assuming the cluster resources can
handle it.
> As a part of it, we have to:
> 1) Set executeInSequence=false for Start/Stop commands (also might make it false for
PrimaryStorageDownload command as well)
> 2) Identify possible implication of turning off the synchronization for those commands,
and fix the problematic places in the code.
