Notes

When you clone your repo make sure you ignore the files inside the .vagrant directory

cat .gitignore 
.vagrant

Vagrant hostmanager plugin (1.5.0) can't get dhcp ip addresses without the configuration found in the sample vagrant files
Vagrant VMWare plugin does not always create new networks correctly. So it is better to use dhcp rather than setting a static private address.
The order virtual machines are created may be important. For example if your provisioning scripts depend on other vms then they should be created first. ie database hosts, web hosts and proxies last
In vagrant (1.7.2) there is a bug, fixed in (1.7.3) that means if you are using virtualbox and receive an error about "a host only network interface attempting to configure via DHCP" you should run the following command as yourself:

VBoxManage dhcpserver remove --netname HostInterfaceNetworking-vboxnet0

When using apache and nginx along with virtualbox, be sure to disable sendfile http://docs.vagrantup.com/v2/synced-folders/virtualbox.html
