This Abiquo Cloud Walkthrough introduces the main concepts for Abiquo users and also presents some basic steps that you can take to get started, so if you have access to the platform, you can follow along. 

Virtual datacenters

To work with the cloud platform, you will use virtual datacenters (VDCs) to access your cloud resources and provision new virtual environments.   A virtual datacenter is an abstraction of a physical datacenter that offers the same capabilities (such as network infrastructure, external storage system, backup, security, etc) with the added advantages of cloud computing:

Virtual appliances

Within your virtual datacenter, virtual appliances (VApps) are folders that contain groups of VMs. When you open a VDC, you will probably see one or more virtual appliances. And you can create more virtual appliances of your own to organize groups of related VMs.

titleClick here to show/hide the task: Create virtual appliance
  1. Open the Virtual datacenters view. It should open at the Virtual appliances tab
  2. Select the virtual datacenter you want to deploy a virtual appliance in
  3. Click the 'Create virtual appliance' button on the main panel of the Virtual Appliances tab
    Create a virtual appliance popup
  4. Click on a virtual appliance name to enter the virtual appliance editor. A virtual appliance will not do anything unless you add at least one VM template to it
  5. The Virtual machines tab of the Virtual appliance editor is divided into: 
    • The Templates panel, which shows the VM templates ready to be deployed
    • The Virtual machines panel, where you will be able to design your virtual application and do actions with it
  6. Simply double-click templates or drag and drop them into the Virtual machines panel

Deploy to launch your VMs

When you deploy a virtual appliance, the platform launches and starts up all the VMs. You can also deploy individual VMs. When a VM is deployed, the platform copies the system disk images to the hypervisor and uses the VM template definition and user configuration to create the VM.

Monitor a VM

Your environment may have VM monitoring configured by default, in which case you can open the virtual appliance's Monitoring tab to view metrics. And you can select the metrics to display and create alarms for VM metrics when you edit the VM.

To monitor a VM

  1. Log in to the platform as an enterprise user
  2. Open the configuration of a deployed VM
  3. Mark the checkbox to Retrieve metrics
  4. Select the metrics you wish to retrieve
  5. Save the virtual machine configuration
  6. Open the monitoring view; the metrics should be displayed. You can also filter the display.

You can retrieve and display metrics to monitor the performance of your VM.

Select VM metrics to display

 

Copy VM disks to create an Instance template 

An Abiquo instance is a copy of the selected disks of a VM at a given time that is stored as a VM template. In private cloud with hypervisors, the platform saves the disks and a copy of the original template definition, unless the VM was captured from outside Abiquo, in which case it saves the configuration of the VM. In private cloud, the platform stores the instance with the original (master) template in the Apps library. In public cloud, the instance template should be available directly in the Apps library.

...

In private cloud, to use an instance template to create a VM, drag and drop or double-click the master template that was used to create the VM. The platform will display a list of the instances for you to select from. In public cloud, you can select the instance directly from the master templates.

Change the configuration of a deployed VM

You can configure VMs before you deploy them, and if your environment supports "reconfigure" operations, you can also configure them after they are deployed. For example, you can add memory and CPU, and additional network interfaces or storage, as well as configuring remote access. If your environment and operating system supports hot-add and hot-reconfigure, you can change the configuration while the VM is powered on. Otherwise, you will need to shut the VM down before you make any changes.

titleClick here to show/hide the task: Reconfigure a VM
  1. To change VM settings, from the VM options menu, select Edit.
    Select Edit from virtual machine options menu  
  2. The VM edit dialog will open. On the General tab, enable remote access, obtain the password and optionally increase CPU and/or RAM. Also make a note of the SSH user and password if they are available.
  3. On the Network tab, open the Private tab and select the default_private_network
    Edit the virtual machine network connections
  4. Add an IP address, and then drag and drop the IP address or the "Auto-generated IP" tag to the VM
  5. Remove the original IP address (so as to not have two IP addresses on the same network)
  6. On the Storage tab, add a hard disk by clicking the + Add button on the right-hand side at the top of the page
    Add storage to your VM
  7. Enter appropriate values for a disk in your environment and click Save.

Connect to your VMs

You can connect to VMs on most hypervisors and providers using VNC (or RDP) by clicking the eye button on the VM control panel (on the left of the following screenshot). You may also neeed to store your SSH public key and telephone number for connecting to the VM using SSH or RDP. See Configure your user account

titleClick here to show/hide the task: Connect to a VM
  1. Obtain the login credentials for the VM.
  2. Select the VM and on the VM control panel, near Remote access, click Show password to obtain the password. (You may also be able to obtain the login credentials from here).
  3. To open a remote access window, click the eye icon on the left-hand side of the control panel.
  4. Enter the remote access password.
  5. At the VM login prompt, enter the VM login credentials.

Make changes to a running virtual appliance

Sometimes you will have a VM that is deployed, while another is not deployed. For example, when you add new VMs or deploy only one VM out of a group. This means that the virtual appliance is deployed but not synchronized with the hypervisor or provider. So the Deploy virtual appliance button changes to become Deploy all VMs button. To deploy the VM(s) that are not allocated, click this button. If you need to remove VMs while the virtual appliance is in this state, you can undeploy or delete individual VMs.
