SSRS report using virtual entity for datasource

Question

I have a SSRS report which uses virtual entity for datasource.
It works fine in dev instance, but after deploying to qual, the report does not execute, even the plugin is not executing.
Can anyone please help me to know if i am missing anything after deployment?

Components which i have deployed are: 1>virtual entity, 2>virtual entity datasource, 3>plugin assembly, 4>SSRS report

Thanks in advance.
