This is the way I ve assigned names to individual VMs  Change YOURNAMEHERE to your desired name   Contents of Vagrantfile   Vagrant configure  2   do  config       Every Vagrant virtual environment requires a box to build off of    config vm box    precise32       The url from where the  config vm box  box will be fetched if it     doesn t already exist on the user s system    config vm box url    http   files vagrantup com precise32 box     config vm define  YOURNAMEHERE do  t    end  end   Terminal output     vagrant status Current machine states   YOURNAMEHERE             not created  virtualbox

I specify the name by defining inside the VagrantFile and also specify the hostname so i enjoy seeing the name of my project while executing Linux commands independently from my device s OS      config vm define  abc  config vm hostname    abc

I found the multiple options confusing  so I decided to test all of them to see exactly what they do    I m using VirtualBox 4 2 16-r86992 and Vagrant 1 3 3   I created a directory called nametest and ran   vagrant init precise64 http   files vagrantup com precise64 box   to generate a default Vagrantfile   Then I opened the VirtualBox GUI so I could see what names the boxes I create would show up as    Default Vagrantfile  Vagrant configure  2   do  config      config vm box    precise64      config vm box url    http   files vagrantup com precise64 box  end   VirtualBox GUI Name    nametest default 1386347922   Comments   The name defaults to the format DIRECTORY default TIMESTAMP  Define VM  Vagrant configure  2   do  config      config vm box    precise64      config vm box url    http   files vagrantup com precise64 box      config vm define  foohost  end   VirtualBox GUI Name    nametest foohost 1386347922   Comments   If you explicitly define a VM  the name used replaces the token  default   This is the name vagrant outputs on the console  Simplifying based on zook s  commenter  input Set Provider Name  Vagrant configure  2   do  config      config vm box    precise64      config vm box url    http   files vagrantup com precise64 box      config vm provider  virtualbox do  vb          vb name    foohost      end end   VirtualBox GUI Name    foohost   Comments   If you set the name attribute in a provider configuration block  that name will become the entire name displayed in the VirtualBox GUI   Combined Example  Define VM -and- Set Provider Name  Vagrant configure  2   do  config      config vm box    precise64      config vm box url    http   files vagrantup com precise64 box      config vm define  foohost      config vm provider  virtualbox do  vb          vb name    barhost      end end   VirtualBox GUI Name    barhost   Comments   If you use both methods at the same time  the value assigned to name in the provider configuration block wins  Simplifying based on zook s  commenter  input Set hostname  BONUS   Vagrant configure VAGRANTFILE API VERSION  do  config    config vm hostname    buzbar  end   Comments  This sets the hostname inside the VM  This would be the output of hostname command in the VM and also this is what s visible in the prompt like vagrant  lt hostname gt   here it will look like vagrant buzbar   Final Code      Vagrant configure  2   do  config          config vm box    precise64          config vm box url    http   files vagrantup com precise64 box          config vm hostname    buzbar          config vm define  foohost          config vm provider  virtualbox do  vb              vb name    barhost          end     end     So there it is   You now know 3 different options you can set and the effects they have   I guess it s a matter of preference at this point    I m new to Vagrant  so I can t speak to best practices yet

You can change vagrant default machine name by changing value of config vm define   Here is the simple Vagrantfile which uses getopts and allows you to change the name dynamically     - - mode  ruby - - require  getoptlong   opts   GetoptLong new       --vm-name          GetoptLong  OPTIONAL ARGUMENT      vm name          ENV  VM NAME       default   begin   opts each do  opt  arg      case opt       when  --vm-name          vm name   arg     end   end   rescue end  Vagrant configure 2  do  config    config vm define vm name   config vm provider  virtualbox  do  vbox  override      override vm box    ubuntu wily64              end         end   So to use different name  you can run for example   vagrant --vm-name my name up --no-provision   Note  The --vm-name parameter needs to be specified before up command   or   VM NAME my name vagrant up --no-provision

If you want to change anything else instead of  default   then just add these additional lines to your Vagrantfile   Change the basebox name  when using  vagrant status    config vm define  tendo  do  tendo    end   Where  tendo  will be the name that will appear instead of default

In case there are many people using your vagrant file - you might want to set name dynamically  Below is the example how to do it using username from your HOST machine as the name of the box and hostname   require  etc  vagrant name    yourProjectName-    Etc getlogin Vagrant configure  2   do  config    config vm box    ubuntu xenial64    config vm hostname   vagrant name   config vm provider  virtualbox  do  v      v name   vagrant name   end end
