Ill try yours in a few,
Ive came up to this for the moment which might not be the perfect algo:

def xen_is_installed(rootdir):
  clear_rpm_db_files (rootdir)
  ts = rpm.TransactionSet(rootdir)
  for mi in ts.dbMatch ():
    name = mi['name']
    if name.find('hypervisor') <> -1:
      # for /lib/modules
      kernel_version = "%s-%s%s" % (mi['version'], mi['release'], 'hypervisor')
      clear_rpm_db_files (rootdir)
      return kernel_version
