Dean Troyer 1a6d4492e2 Periodic formatting cleanup 
This is the semi-irregular comment and docs cleanup.

No functional changes should be here although some code is moved in a
small attempt to sort functions and get things where they need to be.

# bridge. This will happen when you launch your first instance. Upon launch
# you will lose all connectivity to the node, and the VM launch will probably
# fail.
