Vagrant_PyFab-LXD

1. Use vagrant box add to install an Ubuntu 14.04 x64 box for the "vmware_fusion" provider. I have a base box you can use for this purpose; to use my Ubuntu 14.04 x64 base box, add the box with vagrant box add slowe/ubuntu-trusty-x64. (In theory you should be able to use this Vagrant environment with VMware Workstation as well, but only VMware Fusion was tested.)

2. Place the files from the lxd directory of this GitHub repository (the "lowescott/learning-tools" repository) into a directory on your system. You can clone the entire "learning-tools" repository (using git clone), or just download the specific files from the lxd directory.

3. Edit servers.yml to ensure that the box specified in that file matches the Ubuntu 14.04 x64 base box you just installed and will be using. I recommend that you do not change any other values in this file unless you know it is necessary.

4. From a terminal window, change into the directory where the files from this directory are stored and run vagrant up to bring up the VMs specified in servers.yml and Vagrantfile. (By default, it will create and power on only a single VM.)

5. Once Vagrant has finished creating, booting, and provisioning the VM (note you'll need Internet access for this step), log into the VM (named "lxd-01" by default) using vagrant ssh.

6. Add the public LinuxContainers.org image repository by running lxc remote add lxc-org images.linuxcontainers.org.

7. Copy the 32-bit Ubuntu 14.04 container image to your system with the command lxc image copy lxc-org:/ubuntu/trusty/i386 local: --alias=trusty32.

8. Launch a container based on this image with the command lxc launch trusty32 lxd-test-01. This will start a container named "lxd-test-01" based on the "trusty32" image (which is an alias for the image you copied in step 7).

9. Run file /bin/ls and note the output. (You'll use the output for comparison in just a moment.)

10. Open a shell in the 32-bit container you launched in step 8 with the command lxc exec lxd-test-01 /bin/bash.

11. Inside the container, run file /bin/ls and compare the output to the output of the same command you ran outside the container. You'll see that inside the container the file is reported as a 32-bit ELF executable; outside the container the same file is listed as a 64-bit ELF executable.

12. Press Ctrl-D to exit the shell in the container.

13. The container is still running, so stop the container with lxc stop lxd-test-01.
