vagrant asks password at only the first time 'vagrant up'
问题 I made my custom vagrant box for CentOS 6.6. My question is why vagrant always requires password when I 'vagrant up' at only first time. Here is the console log: $ vagrant up Bringing machine 'ns' up with 'virtualbox' provider... ==> ns: Clearing any previously set forwarded ports... ==> ns: Clearing any previously set network interfaces... ==> ns: Preparing network interfaces based on configuration... ns: Adapter 1: nat ns: Adapter 2: hostonly ==> ns: Forwarding ports... ns: 22 => 2222
