I am finding it difficult to find Quickstart VM on official website.
Are these VM's still there on sites, please suggest.
We are in a transition period away from that version of the Cloudera Quickstart VM, as it was old, outdated and nearing end of support. The previous reply from @HadoopHelp is a good suggestion, you can still download and use the HDP "Sandbox".
If you really must have that version of the QuickStart, please see the solution found here.

Yes It is. The compressed file is around ~20GB.
