Hi Neil and all,
    Currently from LAVA deployment of:
Now we installed the lava-server-2017.2 and lava-dispatcher-2017.2 on a server,  from the system can use:
    lava                   lava-dashboard-tool    lava-dispatcher-slave  lava-mount-masterfs    lava-slave             
    lava-daemon            lava-dispatch          lava-master            lava-publisher         lava-tool 
My question is:
1. How to use those command under linux to let it works as the picture shows ?  
2. We try to use $lava-master, the log shows following error, seems the lava-server can't run as a sub-process, since from the git lava-server package there is no lava-server executive command installed, can you help it ?
  File "/usr/local/bin/lava-master", line 4, in <module>
    __import__('pkg_resources').run_script('lava-server==2017.2', 'lava-master')
