Update the YAML configuration files for KVM-based environments to use the "vmw_box" notation for VMware-formatted boxes, even though VirtualBox is not supported for these environments.
For KVM-based environments (which require nested virtualization support), update the README.md to note that VirtualBox is not supported. Also update the Vagrantfile for clearer indications that only VMware-based providers are supported.
Added line to Vagrantfile to read instance_type from instances.yml; this will allow user to specify the AWS instance type to be created.
Addresses #54.
Update the README.md file for multiple learning environments to reflect file name changes, changes in the process for using the learning environment, and changes in the supported/tested software versions.
Edit Consul Upstart configuration to force Consul to bind to secondary Ethernet interface. This fixes problems when using this environment with VirtualBox.
Modify `consul.conf` to force Consul to bind to eth1 instead of eth0. Edit `server.json` to use the correct working directory for Consul, as created by `consul.sh` during provisioning.
Continue standardizing on `machines.yml` instead of `servers.yml` for external data file. Add multi-platform support to environments via provider overrides.
Add information to the README for the OVS multi-bridge configuration to state that Ansible 2.1.1.0 or later is required. Earlier versions had a bug in the OVS modules that would cause an error after the initial run of the playbook.
Add Libvirt XML definitions, Ansible configuration file and playbook, YAML data file, README, and Vagrantfile for an environment enabling users to easily experiment with multi-bridge OVS configurations. Instructions are not yet fully complete. Also tracking a potential bug in the openvswitch_port Ansible module used.
Fix some errors in the provisioning script. Add lines to create 'rkt' group if it doesn't already exist, and to create /var/lib/rkt if it doesn't already exist.
Add new shell script for configuring VMs with CoreOS rkt. Modify Vagrantfile to "pre-download" files if they exist in current directory. Add new multi-platform code to Vagrantfile. Change filenames to adhere to new naming convention.
Commit updated machines.yml with Vagrant boxes specified for different platforms. Commit updated Vagrantfile that uses VAGRANT_DEFAULT_PROVIDER environment variable to choose appropriate box.
Add Vagrantfile and external YAML data file for IPVLAN L3 environment with Docker. Add shell scripts for configuring Docker host VMs. Update README.md for IPVLAN L3 instead of IPVLAN L2.
