Accessing remote files as local
I always tried to access my home network shares from outside (at work i.e.) under windows. After trying many different solutions I found win-sshfs. In short: It adds a network drive to your local windows system. Transport, security etc. is done via ssh. A Manager lets you config the access data:

Packer.IO
Quote:
Packer is easy to use and automates the creation of any type of machine image.
packer.io seems to be a very nice and slim tool to do provisioning of VMs for different cloud solution providers. You can also test your VMs locally via VirtualBox or VMWare.

Your VM has become “inaccessible.”
After some time a restarted playing around with my private vagrant setup when i came across this message, after trying to “up” my machines:
Your VM has become “inaccessible.”
So my setup is broken and I had to repair the machines. Luckily this is very easy:
$ vboxmanage list vms
"<inaccessible>" {652819f9-a4c4-4b18-b7e0-ea8e8bcec828}
There you can see the inaccessible vm and its id. Just unregister it and vagrant will be able to bring up your system from scratch.
$ vboxmanage unregistervm 652819f9-a4c4-4b18-b7e0-ea8e8bcec828
$ vagrant up
