This code produces the following reference qualifier:

Active is true

AND Name is not "Red Hat EL 6.x English - 64 bit"

AND VM Type is <value of vm_type variable>

AND Data center = <value of datacenter variable>

if Launch Method is not "Manual" then an extra condition is added:

AND VCAC Flag is true
