Vagrant unable to start VMs - (force shutdown, unable to find net/ssh)

[fedesilva]

I am trying to start a stock (generated by vagrant) Vagrantfile with ubuntu 14.04 machines from chef/ubuntu-14.04 and/or ubuntu cloud images and apparently vagrant is forcing shutdown before connecting to the vm and is reporting failure to require "net/ssh"

Versions are

f@Omoikane:~/tmp/vms$ vagrant --version
Vagrant 1.7.2
f@Omoikane:~/tmp/vms$ vboxmanage --version
4.3.26r98988

Host OS: Mac OS X 10.10.3

Here is sample output without debug flag

Here is a link to the full vagrant output with --debug on:

Virtualbox works correctly if one installs a machine manually.

For the sake of completeness here is the installed plugin list (after removing everything, nothing changed)

f@Omoikane:~/tmp/vms$ vagrant plugin list
vagrant-share (1.1.3, system)

Tried downgrading to Vagrant 1.6.5 without success. Same exact error output.

This happens with manually installed vagrant and virtualbox and also with them installed via Homebrew Cask (fwiw).

FIXED!

Turned out an old .vagrant.d was being used as restored from Time Machine (old machine died, new machine is restored from old backup).

Moved away (kept for testing later) the .vagrant.d directory and problem solved.

I would not close this issue as this can happen to someone else and the output is not helpful plus still no idea what is broken in the old one.

Thanks for the great debugging. Do you have any suggestions of how Vagrant might better detect this? Old ".vagrant.d" directories certainly do cause problems but there isn't a good sentinel file to detect when this is the case. I'm not sure if we can actually error here. :(
