Vagrant commands manage

A VirtualBox machine with the name 'vm_name' already exists. Please use another name or delete the machine with the existing name, and try again.

I listed current running virtual machines from the command line :

vboxmanage list vms

Result :

"vm_name" {8ba467b7-da96-4f68-9bf8-671dd6f0d007}

Then proceeded with the removal of the offending virtual machine :

VBoxManage unregistervm 8ba467b7-da96-4f68-9bf8-671dd6f0d007 --delete

vagrant up --provision

The Bootstrap Process

So George's request for /about-us has been handed to Drupal, and index.php is ready to bootstrap Drupal. What does that mean?

A quick summary

At a code level, we're talking about the drupal_bootstrap function, which lets you pass in a parameter to tell it which level of bootstrap you need. In almost all cases, we want a "full" bootstrap, which usually means "this is a regular page request, nothing weird, so just give me everything."
