# Create render layer

r1 = rs.createRenderLayer("char_beauty")


# Create collections

c1 = r1.createCollection("char")

so.setattribute('primaryVisibility')

It looks like your code is missing a finalize method call on the override:

import maya.app.renderSetup.model.override as override
import maya.app.renderSetup.model.selector as selector
import maya.app.renderSetup.model.collection as collection
import maya.app.renderSetup.model.renderLayer as renderLayer
import maya.app.renderSetup.model.renderSetup as renderSetup
import maya.cmds as cmds

rs = renderSetup.instance()    

# Create render layer
r1 = rs.createRenderLayer("char_beauty")

# Create collections
c1 = r1.createCollection("char")
c2 = r1.createCollection("trk_geo")
c2pv=c2.createCollection("PV")
c2pv.getSelector().setFilterType(2)

# Create override
so = c2.createOverride('PV', override.AbsOverride.kTypeId)
so.finalize('visibility')

If you don't know the name of the attribute, you may skip the last finalize call, then assign the override manually by drag-and-dropping the attribute from the Attribute Editor and then call the print so.attributeName() to see the actual name.
