> Support parallel VM deployment with CloudStack
> ----------------------------------------------
>
> Key: CLOUDSTACK-2843
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2843
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.2.0
> Reporter: Alena Prokharchyk
> Assignee: Alena Prokharchyk
> 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.
