Subject: Re: Samba Connecting, cannot transfer files
If you are looking for a fast way to get VirtualBox VM's up and running for
LAMP development you should install and look into using Vagrant. It is a
provisioner which uses Ruby to automatically build VM's in VirtualBox. I
have a simple setup of provisioning scripts that stand up LAMP servers
using Vagrant. Feel free to use it, or make it your own.
