i have vagrantfile defines multiple machines. 1 of these machines used daily development, other 1 exists solely occasional integration testing. is there way make vagrant never bring secondary machine default? when run vagrant up , i'd bring default machine defined as: config.vm.define "centos7", primary: true |centos7| and never bring secondary machine defined as: config.vm.define "centos6", primary: false |centos6| i know can run vagrant centos7 not bring other machine, i'd make life easier on consumers of project , not have them inadvertently start 2 vms simultaneously on machines, since second 1 irrelevant daily needs. you can define follow config.vm.define "centos6", autostart: false , primary: false |centos6| the autostart setting allows tell vagrant not start specific machines when you'll runn vagrant "centos7" automatically start, "centos6" not start. if want run test you'll force ...

the question not 'how to' generate such key. there tons of answers. simple timestamp others not unique enough chars rand(). what thougth is, why not combine both? if take timestamp in seconds or milliseconds , add random chars (but no numbers) in between, wouldn't result random , unique string? the question not specific 1 programming language give code made in php: $token = (string) preg_replace('/(0)\.(\d+) (\d+)/', '$3$1$2', microtime()); $l = strlen($token); $c = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz"; for($i = 0; $i < $l; $i++){ $token = substr_replace($token, $c[rand(0, 51)], rand(0, $l+$i), 0); } echo $token; i'm realy looking forward randomness-pro's answer! thanks ;) lenny i prefer generate guid. here code you. function getguid(){ if (function_exists('com_create_guid')){ return com_create_guid(); }else{ mt_srand((double)microtime()*1...
