cloud-init "nocloud" networking setup

cloud-init is absolute cancer. Its code is horrible. It has no documentation at all.

It took me 5 fucking hours to figure out how to properly configure networking on recent cloud-init (Ubuntu 16.04 cloud image) with local datasource.

It's not mentioned anywhere you need to provide dsmode: local. (but only if you need network-config, besides that everything is fine; someone below noted that -m flag does the same thing, good to know) Of course nobody needs documentation for network-config format either. (cloudinit/net/__init__.py is a protip, enjoy the feces dive)

Oh, and by the way - no, it's not possible to provide network-config to uvt-kvm without patching shit.

How to transition from EasySIMBL to SIMBL

#How to transition from EasySIMBL to SIMBL

( ~ is your home directory )

  1. Launch EasySIMBL.app. Turn OFF Use SIMBL checkbox. Quit EasySIMBL.
  2. Remove ~/Library/ScriptingAdditions/EasySIMBL.osax if exists.
  3. SIMBL directory and EasySIMBL.osax located in ~/Library/Containers/ is not needed. Find from Finder or find command like find ~/Library/Containers -name "*SIMBL*" -ls and remove manually if exists.
  4. Restart Mac (just in case).
  5. Install SIMBL-0.9.9 (original SIMBL-0.9.9.pkg is not code signed. So open from context menu)
  6. Done.
