This configuration was tested using Vagrant 1.8.1, VMware Fusion 8.1.0, the Vagrant VMware plugin, and Ansible 1.9.1. Other versions of these products are likely to work, but haven't been tested. + +## Contents + +* **ansible.cfg**: This Ansible configuration file instructs Ansible to use an inventory file named `hosts` in the current directory, to use the default vagrant user (`vagrant`) and default insecure Vagrant SSH private key, and to use the Vagrant-generated Ansible inventory file (found, by default, in `./.vagrant/provisioners/inventory/vagrant_ansible_inventory`). + +* **machines.yml**: This YAML file contains a list of VM definitions and associated configuration data. It is referenced by `Vagrantfile` when Vagrant instantiates the VMs. Generally the only change this file needs is to ensure the "box" value correctly references the Vagrant box you're using. The "ip_addr" value is also required in order to build the Ansible inventory file; you may want to edit this to a value appropriate for your environment. + +* **provision.yml**: This YAML file is an Ansible playbook that configures the VMs created by Vagrant when they are first provisioned. Ansible is called automatically by Vagrant; you do not need to invoke Ansible separately. No changes are needed to this file. + +* **README.md**: The file you're currently reading. + +* **Vagrantfile**: This file is used by Vagrant to spin up the virtual machines. This file is fairly extensively commented to help explain what's happening. You should be able to use this file unchanged; all the VM configuration options are stored in `machines.yml`. + +## Instructions + +These instructions assume you've already installed VMware Fusion, Vagrant, the Vagrant VMware plugin, and Ansible. Please refer to the documentation for those products for more information on installation or configuration. + +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. Copy the files from the `kvm` directory of this repository (the "learning-tools" repository) to a directory on your system. You can clone the entire "learning-tools" repository (using `git clone`), or just download the specific files from the `kvm` directory. + +3. Edit `machines.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 according to the instructions in `machines.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 "kvm-01" by default) using `vagrant ssh`. + +You can now use this VM to do any testing or experimentation with KVM and Libvirt. diff --git a/ovs-geneve/Vagrantfile b/ovs-geneve/Vagrantfile new file mode 100644 index 0000000..6f689c1 --- /dev/null +++ b/ovs-geneve/Vagrantfile @@ -0,0 +1,76 @@ +# -*- mode: ruby -*- +# vi: set ft=ruby : + +# Specify Vagrant version, Vagrant API version, and desired clone location +Vagrant.require_version '>= 1.6.0' +VAGRANTFILE_API_VERSION = '2' +ENV['VAGRANT_DEFAULT_PROVIDER'] = 'vmware_fusion' +ENV['VAGRANT_VMWARE_CLONE_DIRECTORY'] = '~/.vagrant' +#ENV['VAGRANT_DEFAULT_PROVIDER'] = 'virtualbox' +#ENV['VAGRANT_DEFAULT_PROVIDER'] = 'vmware_appcatalyst' + +# Require 'yaml' module +require 'yaml' + +# Read YAML file with VM details (box, CPU, and RAM) +machines = YAML.load_file(File.join(File.dirname(__FILE__), 'machines.yml')) + +# Create and configure the VMs +Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| + + # Always use Vagrant's default insecure key + config.ssh.insert_key = false + + # Iterate through entries in YAML file to create VMs + machines.each do |machine| + config.vm.define machine['name'] do |srv| + + # Don't check for box updates + srv.vm.box_check_update = false + srv.vm.hostname = machine['name'] + srv.vm.box = machine['box'] + + # Configure default synced folder (disable by default) + if machine['sync_disabled'] != nil + srv.vm.synced_folder '.', '/vagrant', disabled: machine['sync_disabled'] + else + srv.vm.synced_folder '.', '/vagrant', disabled: true + end #if machine['sync_disabled'] + + # Assign additional private network + if machine['ip_addr'] != nil + srv.vm.network 'private_network', ip: machine['ip_addr'] + end # if machine['ip_addr'] + + # Configure CPU & RAM per settings in machines.yml (Fusion) + srv.vm.provider :vmware_fusion do |vmw| + vmw.vmx['memsize'] = machine['ram'] + vmw.vmx['numvcpus'] = machine['vcpu'] + if machine['nested'] == true + vmw.vmx['vhv.enable'] = 'TRUE' + end #if machine['nested'] + end # srv.vm.provider vmware_fusion + + # Configure CPU & RAM per settings in machines.yml (AppCatalyst) + srv.vm.provider :vmware_appcatalyst do |vmw| + vmw.vmx['memsize'] = machine['ram'] + vmw.vmx['numvcpus'] = machine['vcpu'] + #vmw.vmx['guestos'] = 'other3xlinux-64' + if machine['nested'] == true + vmw.vmx['vhv.enable'] = 'TRUE' + end #if machine['nested'] + end # srv.vm.provider vmware_appcatalyst + + # Configure CPU & RAM per settings in machines.yml (VirtualBox) + srv.vm.provider :virtualbox do |vb| + vb.memory = machine['ram'] + vb.cpus = machine['vcpu'] + end # srv.vm.provider virtualbox + end # config.vm.define + + # Provision the VM with Ansible + config.vm.provision 'ansible' do |ansible| + ansible.playbook = 'provision.yml' + end # config.vm.provision + end # machines.each +end # Vagrant.configure diff --git a/ovs-geneve/ansible.cfg b/ovs-geneve/ansible.cfg new file mode 100644 index 0000000..b3a4567 --- /dev/null +++ b/ovs-geneve/ansible.cfg @@ -0,0 +1,5 @@ +[defaults] +inventory = ./.vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory +private_key_file = ~/.vagrant.d/insecure_private_key +remote_user = vagrant +host_key_checking = False \ No newline at end of file diff --git a/ovs-geneve/machines.yml b/ovs-geneve/machines.yml new file mode 100644 index 0000000..d683597 --- /dev/null +++ b/ovs-geneve/machines.yml @@ -0,0 +1,13 @@ +--- +- name: kvm-01 + box: slowe/ubuntu-trusty-x64 + ram: 1024 + vcpu: 1 + ip_addr: 192.168.100.100 + nested: true +- name: kvm-02 + box: slowe/ubuntu-trusty-x64 + ram: 1024 + vcpu: 1 + ip_addr: 192.168.100.101 + nested: true diff --git a/ovs-geneve/provision.yml b/ovs-geneve/provision.yml new file mode 100644 index 0000000..88239d7 --- /dev/null +++ b/ovs-geneve/provision.yml @@ -0,0 +1,18 @@ +--- +- hosts: "all" + sudo: "yes" + remote_user: "vagrant" + + tasks: + - name: "Install KVM and Libvirt" + apt: + state: "present" + update_cache: "yes" + name: "{{ item }}" + with_items: + - qemu-kvm + - libvirt-bin + - git + - autoconf + - libtool + - virtinst diff --git a/ovs-geneve/vxlan.xml b/ovs-geneve/vxlan.xml new file mode 100644 index 0000000..826f3d3 --- /dev/null +++ b/ovs-geneve/vxlan.xml @@ -0,0 +1,6 @@ + + vxlan-net + + + +
