I have the next issue: when I configure ElasticSerch to connect remotely from Windows host (ElasticSearch is running in Linux VM) I've put "network.host: 0.0.0.0" .
But when I run de bin to start ElasticSearch I get this error:
ERROR:  bootstrap checks failed
: max file descriptors  for elasticsearch process is too low, increase to at least 
: max virtual memory areas vm.max_map_count  is too low, increase to at least 
Nevertheless, if I run ElasticSearch to been accessed from localhost I have no errors from file descriptor neither virtual memoryonly WARNINGS.
