Subject [jira] [Created] (CLOUDSTACK-2843) Support parallel VM deployment with CloudStack
Date Tue, 04 Jun 2013 22:27:20 GMT
Alena Prokharchyk created CLOUDSTACK-2843:

             Summary: Support parallel VM deployment with CloudStack
                 Key: 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

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.
