Multiple instance creation issue

[Gaspare A Silvestri]

Hello everybody,

when i try to concurrently create multiple instances, with different 
scenarios (same template, different templates, same user, different 
users), I have to wait that the first (async) creation job has been 
completed to execute the second, and so on.

Where could be the problem?

I'm currently using CloudStack 4.0 with VMware vSphere 5.1 .

Thanks in advance,

Gaspare
