Now we have completed the developments of "keepalived"configuration generation through the lvs extension.It supports the regeneration of master and slave configuration in the case of real server scale up and down. Please refer the INSTALL.md[1] file which describes how to install the lvs extension for "keepalived" configuration generation.
Related developments are pushed into the "lvs_extension" branch.
