-------------------------------------------------

             Summary: CS does not display  how much overcommited resourced 
(ram/cpu) are available(or leftover after deploying a vm) (Dashboard displaying 
actual resource)
                 Key: CLOUDSTACK-1538
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1538
             Project: CloudStack
          Issue Type: Improvement
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.2.0
            Reporter: prashant kumar mishra


At any point of time it is not known how much overcommited resources are 
leftover(until unless admin does manual calculation) ,so that admin can choose 
a proper service offering to deploy vm without failure.

==========
Actual Memory=1GB

Overcommit ratio for Memory=2

Overcommited Memory=2GB

1-Deployed a vm with service offering having Memory=1.5 GB 
2-To deploy second vm he used Service offering having Memory=1GB (deployment 
failed)
3-He has to try again with service offering=512MB

If  it is known how  much Overcommited Memory is available or leftover,  step 2 
failure can be avoided by choosing a proper service offering at first place.
