Replace PHP with HHVM?

I am struggling finding a manually way to replace PHP with HHVM but no change to get a positive result. I am using Virtualmin as it is in a test environment. I installed HHVM in terminal, then when I tried to install it for Apache using hhvm script I get

Detected enabled fcgid.load configuration, setting up integration
Force enabling module hhvm_fcgid.conf
WARNING: Unsupported hhvm_fcgid, not configuring
Restaring Apache

Without Virtualmin, just a LAMP installation, HHVM replaces perfectly PHP

Please those who managed replacing PHP with HHVM please give a solution. Thank you.
