             Summary: Unable to create a deployment for VM: better error reportintg for InsufficientServerCapacityException
                 Key: CLOUDSTACK-10116
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10116
             Project: CloudStack
          Issue Type: Improvement
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.10.0.0
            Reporter: Jevgeni Zolotarjov


An attempt to create new instance failed with an error:
*Unable to create a deployment for VM*

For understanding the problem, I had to 
1. analyze the logs, 
2. Locate InsufficientServerCapacityException and understand what it means.
2. multiply [service offering core count] x [service offering MHz] and 
3. check it against the remainder from the indicator on the dashboard. 
4. consider cpu.overprovisioning.factor

Expected:
The clear error for the user about the real reason of the problem is good solution for this problem.

The text could be: "Insufficient CPU resources to create new VM. You can try increasing cpu.overprovisioning.factor system variable. Be careful with this, cause it might impact performance of your other VMs."
