Virtual datacenters
To work with the cloud platform, you will use virtual datacenters (VDCs) to access your cloud resources and provision new virtual environments. In a virtual datacenter you can work with virtual resources, including network infrastructure, external storage systems, backups, security, and so on. A virtual datacenter also has the advantages of cloud computing:
Virtualization
Pay-as-you-go billing
Quick scalability
Technology and hardware abstraction.
A virtual datacenter offers datacenter infrastructure as a service, so you can run your applications more cheaply and with greater flexibility. In your VDC, you will find compute resources and other resources, such as volumes and public IPs, that you an attach to your VMs. Each VDC has similar features and functionality and each VDC belongs to a private cloud datacenter or public cloud region. In private cloud, a VDC uses a hypervisor of one type only and in public cloud, a VDC can be created by the provider, e.g. in AWS a VDC corresponds to a VPC, or by the platform.

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.
Within your virtual appliance folders, you can easily create VMs by dragging and dropping VM templates (or by double-clicking on the VM templates). And if your environment supports virtual appliance specifications (VApp specs), to create a virtual appliance from a saved configuration, you can just select one of these blueprints.

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 you deploy a VM, the platform copies the system disk images to the hypervisor and uses the VM template definition and user configuration to create the VM.

To start the virtual appliance, click the Deploy virtual appliance button in the top right-hand corner of the Virtual machines panel. This will deploy and start the VMs in the virtual appliance. You can also deploy virtual appliances using the controls that appear when a virtual appliance is selected in the virtual datacenter view. When the Virtual appliance is deployed, the Deploy button becomes an Undeploy button or a Deploy all VMs button. To destroy all the VMs and all your data on the hard disks, click the Undeploy button. |

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.
...

Open a virtual appliance
...
Shut down the VMs you want to copy the disks from to make the instance. For each VM, click the stop or 'power button' and if your VM has the appropriate configuration (VM tools), select the option to shut down the VM. Otherwise, you can connect directly to the VM to perform a graceful shutdown, or select the option to perform a hard power off.
...
Select one of the VMs to instance
...
Select the disks
If you want to create more instances, select Keep window open
...
Click Create Instance. The platform will lock the VM to create the instance
If you kept the dialog open, click Back to list and create more instances as required, then close the dialog
In private cloud, to use an instance template to create a VM, select 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 because it is at the same level as 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.
Screenshot: Reconfigure a VM, General Information
Connecting your VMs: If you don’t configure a network interface card (NIC) before you deploy your VM, the platform will configure a default one. You can add NICs to your VMs to add IPs in a private network for communication within the VDC, or another type of network with access outside the VDC, as configured by your administrator.
Add hard disks to save your data: Hard disks on the hypervisor datastore are not persistent and when the user undeploys the virtual appliance, the hard disks are destroyed. To create a hard disk, edit the VM and go to the Storage tab.
...
| title | Click here to show/hide the task: Reconfigure a VM |

...
To change VM settings, from the VM options menu, select Edit.
...
...
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.
...
Add an IP address or add the "Auto-generated IP" tag to the VM
...
Remove the original IP address (so as to not have two IP addresses on the same network)
...
On the Storage tab, add a hard disk by clicking the + add button at the bottom of the top of the page
...
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 console button on the VM control panel. To connect in public cloud, before you deploy your VM, you will need to store your SSH public key in your user account. And in some platforms you will need to enter your telephone number in your user account for connecting to the VM using SSH or RDP. See Edit your user account details

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.
To destroy a standard VM in the hypervisor, undeploy it. The platform will maintain the configuration of the undeployed VM until you delete it. If you deploy the VM again, the platform copies the template again from the Apps library. And any changes you made to the configuration and the disks are lost.
