Sync: VBox, Vagrant, and Guest Additions ...

Are you seeing:

[default] Importing base box 'qa-vm'...
[default] The guest additions on this VM do not match the install version of
VirtualBox! This may cause things such as forwarded ports, shared
folders, and more to not work properly. If any of those things fail on
this machine, please update the guest additions and repackage the
box.

Guest Additions Version: 4.1.0
VirtualBox Version: 4.1.8

I followed the steps posted by Yodi.
It looks like you can change the iso name to match the version needed.

* Important * On the vm.
I used the following:


wget -c http://download.virtualbox.org/virtualbox/4.1.8/VBoxGuestAdditions_4.1.8.iso
sudo umount /mnt
sudo mount VBoxGuestAdditions_4.1.8.iso -o loop /mnt
sudo sh /mnt/VBoxLinuxAdditions.run


Thank you Yodi.

This appears to have worked on both:
* centos 6 2.6.32-71.el6.x86_64 x86_64 GNU/Linux
* ubuntu 2.6.32-33-server #70-Ubuntu SMP Thu Jul 7 22:28:30 UTC 2011 x86_64 GNU/Linux

Package version list CentOS

Have you ever needed to share a package list?




rpm -qa --qf '%{NAME} %{VERSION}-%{RELEASE} %{ARCH}\n' > pkglist.txt

Vagrant couldn't determine the SSh port for you VM!

Saw the following message on vagrant up and vagrant ssh:

"[mongrel@localhost massiveapp]$ vagrant ssh
Vagrant couldn't determine the SSH port for your VM! This is a rare,
exceptional event, and a bug should be filed. Please try recreating your
VM (vagrant destroy, then vagrant up). Sorry!"

Resolved by changing the vm.name.

Install Ruby 1.9 on CentOS

In case you did not know and because I found out the hard way;

Attention: Ruby 1.9.2 now includes RubyGems so there's no need to install it separately. As a matter of fact, if you try doing so you will get an error like:

rubygems-1.3.7/lib/rubygems/source_index.rb:68:in `installed_spec_directories': undefined method `path' for Gem:Module (NoMethodError

DevOps

“DevOps”. This word was coined by Patrick Debois to describe “an emerging set of principles, methods and practices for communication, collaboration and integration between software development (application/ software engineering) and IT operations (systems administration/infrastruc- ture) professionals.”1. In other words, software systems tend to run more smoothly when the people who are writing the code and the people who are running the servers are all working together.
