Yep libvirt supports a config file for credentials

  http://libvirt.org/auth.html#Auth_client_config


For vmware esx IIRC you would create

  $HOME/.config/libvirt/auth.conf

containing

  [credentials-prod]
  username=fred
  password=123456

  [auth-esx-test1.example.com]
  credentials=prod

  [auth-esx-test2.example.com]
  credentials=prod

  [auth-esx-test3.example.com]
  credentials=prod
