Virtualbox - Renaming Error

If you are receiving an error like the one below, this page will help you resolve it.

A customization command failed:

["modifyvm", :id, "--name", "protobox"]

The following error was experienced:

#<Vagrant::Errors::VBoxManageError: There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["modifyvm", "5d9acc2a-ffb2-406e-83a0-5073e78ac6ab", "--name", "protobox"]

Stderr: VBoxManage: error: Could not rename the directory '/home/protobox/VirtualBox VMs/protobox_default_1391243423387_88058' to '/home/protobox/VirtualBox VMs/protobox' to save the settings file (VERR_ALREADY_EXISTS)

Please fix this customization and try again.

This appears to be a common vagrant error without pre-set solution yet [1][2][3]. In our experience trying the following helped resolve the issue depending on your configuration:

  • vagrant reload - this should hopefully clear up the issue
  • open virtualbox application, if you see an old machine on the left delete it if you don't need it
  • try a vagrant destroy -f to clear the old one out
  • if all else fails you can manually delete /home/protobox/VirtualBox VMs/protobox_default_1391243423387_88058 (folder from the error above) and vagrant up should work

If none of these work, please file an issue at the vagrant github repository.
