Subject Re: Simulator : Error while creating a snapshot from a VM
Date Thu, 20 Mar 2014 16:52:53 GMT
Meghna,

I realized one thing that is missing from 4.3 and 4.2 that I added (it's on
4.4 and master though).  Here is the commit
https://github.com/apache/cloudstack/commit/dfb81ac1274d8ebe4a47223d10f3de44aa9091bf
.

If you apply that and re-build, it should fix the create VM snapshot issue.
