You need to set host_string an example would be:

from fabric.context_managers import settings as _settings

def _get_hardware_node(virtualized):
    return "localhost"

def mystuff(virtualized):
    real_host = _get_hardware_node(virtualized)
    with _settings(
        host_string=real_host):
        run("echo I run on the host %s :: `hostname -f`" % (real_host, ))
