The poller.py is from the package rhn-virtualization-host - you may
check this with :

# rpm -qf /usr/share/rhn/virtualization/poller.py
rhn-virtualization-host-1.0.1-41

Information on the package :

rpm -qi rhn-virtualization-host


The file poller.py polls the Dom0 for currently running DomU's ( guests ).

I am not entirely sure why you have it installed. It is simple enough to
remove it:

yum remove rhn-virtualization-host
