Subject Simulator : Error while creating a snapshot from a VM
Date Thu, 20 Mar 2014 10:56:08 GMT
Hi All,

I have been seeing an error while creating a snapshot from a VM in the
Simulator.
I faced this issue on both the versions 4.2 and 4.3.

Can anyone help me or provide pointers.

A similar NullPointer error is also thrown while creating a VM from a
personal template created from an existing VM.

Error from vmops.log :

ERROR [cloud.api.ApiServer] (31312594@qtp-24163675-2:) unhandled exception
executing api command: createVMSnapshot
java.lang.NullPointerException
