-# choose “vagrant” as the password -# set up sudo permissions: visudo -# Add the following lines at the bottom: -# # Vagrant user should be able to sudo -# %admin ALL=NOPASSWD: ALL

-# Comment out the following line: -# Defaults requiretty -# (otherwise ssh <command> doesn’t work)

-# Add the variable “PATH” to the “Defaults env_keep” list. -# (otherwise sudo cleans the path, and loses ruby, which ohai needs) -# (See http://stackoverflow.com/questions/257616)

-# Add the usr/sbin and /sbin to the path: echo ‘export PATH=$PATH:/usr/sbin:/sbin’ >> ~vagrant.bashrc

• chmod 755 .ssh
• curl http://github.com/mitchellh/vagrant/raw/master/keys/vagrant.pub > .ssh/authorized_keys
• chmod 644 .ssh/authorized_keys

Fiddle with MAC addres

• sudo /sbin/ifconfig
• write down MAC address of eth0 (eg. 08:00:27:60:AE:41)

sudo yum clean headers packages dbcache expire-cache

• shut down vm

Export and package

• vagrant package –base vagrant-centos –vagrantfile CentOS-6.3-x86_64-minimal.box
