Simulator : Error while creating a snapshot from a VM
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

We aren't going to release another 4.2.x release, so only 4.3.x applies here.

I was able to create a snapshot in 4.2 simulator after applying the changes
from
https://github.com/apache/cloudstack/commit/dfb81ac1274d8ebe4a47223d10f3de44aa9091bf
patch
suggested by David.
Just a suggestion, if the fix is present in 4.4 can we have this 4.3 and
4.2 as well.
Thanks
Meghna.

RE: Simulator : Error while creating a snapshot from a VM
Posted by Santhosh Edukulla <sa...@citrix.com>.
Meghna,
Please check the code from master or 4.4, there were few fixes added to simulator code, few cases failing in earlier versions were now working.
Also, not all cases are possible with simulator i believe, few cases still has dependencies inbuilt. first check simulator code from master\4.4 first and then see if it works, else log a bug, so we can look at it.
Santhosh

Re: Simulator : Error while creating a snapshot from a VM
Posted by David Grizzanti <da...@sungard.com>.
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.
