Display virtual datacenter networks

To display the networks available to a virtual datacenter:
  1. Go to Virtual datacenters → select virtual datacenter → Network.
  • The default network is highlighted with a star symbol
  • A network with an internet gateway is highlighted with a globe symbol.

API Features

Virtual datacenter networks are available in the Abiquo API. For example, see VirtualDatacentersResource and PrivateNetworksResource.


Network tab in virtual datacenter highlighting default network and internet gateway

In the Networks list, to view the pool and allocation of IPs:

  • To see all the IPs in the virtual datacenter, click the All button on the top of the list
  • To see the IPs in a VLAN, click the VLAN name

You can then:

  • use the slider at the bottom of the list to move through the pages 
  • filter the list by entering text in the search box. The filter works with all the columns of the table including:
    • IP Address
    • MAC address
    • VLAN name
    • Virtual appliance using the IP
    • VM using the IP
    • Provider ID of the entity using the IP (for example, a load balancer)




Create a private network

Private networks are only available within a virtual datacenter. However, your cloud provider may configure an external gateway for your virtual datacenter.

To create a private network:

  1. Go to Virtual datacenters → select virtual datacenter → Network
  2. Click the  button  and complete the form

Use private networks in public cloud

In public cloud providers that support networks:
  • When you onboard resources, the platform will onboard private networks, including details of IP addresses not used by VMs
  • You can synchronize private networks
  • You can create additional private networks in the provider
    • When you create a custom private network in AWS, you can choose the Availability Zone. Availability Zones enable users to deploy VMs separately, with high availability. 
    • To deploy in an Availability Zone, assign a private IP address in the network belonging to that Availability Zone


When using the platform, DO NOT DELETE networks directly in the provider because this may cause inconsistency. The synchronization process is especially designed to onboard public cloud elements when you begin to work with a public cloud provider.




Create IP addresses in private networks

To create new IP addresses in a private network do these steps.

  1. Go to Virtual datacenters → optionally select Virtual datacenter → Networks → Private → select Private network
  2. Click the Add button in the top right-hand corner of the Private IPs page. 
    OR
  3. Add the IP directly to a VM: Go to Virtual datacenters → edit VM → Network and select an automatically generated IP or click the + add button

Enter the number of IPs and the first IP address in the range. The first IP address must be a new address that does not already exist in the network. After creating the first IP address, the platform will try to create the other IPs and it will skip any existing IP addresses. 

For example, if you have IP addresses in network 30.30.30.30, which are 30, 33, and 34 and then you request 3 new IPs from 30.30.30.31. The new IPs created should be as follows: 31, 32, 35. 
IP Addresses
30.30.30.30
30.30.30.31
30.30.30.32
30.30.30.33
30.30.30.34
30.30.30.35
 Click here to show/hide IPv6 details

When you add IPv6 addresses on strict networks, you don't need to set the starting address.

On non-strict IPv6 networks, Abiquo recommends that you create an automatic IP address, or you can enter an IP address manually as shown here.




Reserve IP addresses in private networks

The private IP reservation feature will prevent users from assigning reserved IPs to VMs within the platform. The platform does not display reserved IPs to allow users to select them for VMs. You can only assign reserved IPs to VMs from outside of Abiquo, for example, using a script. If you onboard a VM with a reserved IP, the platform logs a warning message.

Privilege: Manage private IP reservation

To reserve private IPs:

  1. Go to Virtual datacenters → Networks → Private
  2. Select the IPs and click the lock button
  3. Enter the reason for the reservation
  4. The platform will list the VMs in the virtual datacenter. Optionally select VMs to indicate where the IPs might be used. Note that you must check that the VMs are able to use these IPs. This selection does not assign the IPs to VMs.

The platform will display a padlock symbol beside the IP reserved addresses.



Edit a private network

To edit a private network
  1. Select the network
  2. Click the Edit button  above the Networks list:
  3. You can change the network name, gateway, DNS settings, and make the network the new default for this virtual datacenter.
  4. Click Save

The new settings will apply to all VMs deployed after you save the network.




Delete a private network

You can delete a private network if no VMs are using its IPs and it is not the default network for the virtual datacenter.

To delete a private network:

  1. Go to Virtual datacenters → Network → Private
  2. Select the network and click the delete button  above the Networks list. 




Display onboarded external networks

The platform automatically onboards external networks when you onboard virtual datacenters from vCloud Director.

To display onboarded external networks

  1. Go to Virtual datacenters → Network → Select vCloud VDC → External



Delete an onboarded external network

If an onboarded network has been deleted in the provider, its name will display in light gray text. If a VM is using an IP from this network, then you cannot deploy the VM.

If there are no VMs using the IPs of an external network that was already deleted in the provider, to delete the network in the platform, select it and click the Delete button.



Set default virtual datacenter networks

If you deploy a VM without assigning a NIC, Abiquo will add one in the virtual datacenter's default network.

To set a new or existing network as the default:

  1. When you create or edit the network, select the Default network checkbox. The new default network will apply to all VMs deployed after you set it.  

In private cloud, if you set a public network as the default, remember to obtain IP addresses for your VMs before you deploy!



Obtain IP addresses from public networks

In public networks you can reserve or purchase public IP addresses for your VMs. Reserved IPs may be charged while they are reserved, even if they are not used in VMs. You can also reserve public IPs directly from the Edit VM dialog.

Privilege: Manage public IPs

To add new public IP addresses to your virtual datacenter:

  1. Click the + Add button in the top right corner of the Public IPs page to display the list of available Public IPs
    1. To move between pages, use pagination controls such as arrows and page numbers
    2. Filter your search by entering an IP address or VLAN name in the filter box
  2. Select IP addresses to add them to your virtual datacenter 
  3. Click Add to reserve the IPs

The platform will add the IPs to your VDC

The following screenshot shows two IP addresses selected. 




Obtain public IP addresses in public cloud

During onboarding from public cloud, the platform will onboard existing public IP addresses in providers that support them, such as AWS and Azure. You can obtain them from the provider and assign them to your virtual datacenters and VMs.

Amazon may charge for Elastic IP addresses as soon as you reserve them for your virtual datacenter. Therefore you should reserve your IP addresses just before you deploy and check they are deleted when you undeploy your VMs.


To add public IP addresses to your virtual datacenter, so that you can later assign them to your VMs:

  1. Select a virtual datacenter in public cloud and go to Network → Public
  2. Click the add button  in the top right corner of the PUBLIC IPs page
  3. To add the public IP to a virtual datacenter, click the Add to VDC link near the IP address

Now when you edit a VM in the VDC and go to Network → Public, you will see the public IP address and you can add it to your VM.




Synchronize public IP addresses with the cloud provider

To onboard any public IP addresses that were already created in your cloud provider, or update changes made directly in the provider

  1. Go to Virtual datacenters → Network → Public
  2. Click the Synchronize public IPs button




Release a reserved public IP address

You can release a public IP if it is not assigned to a VM. To release a public IP, select the IP in the list and click the Delete button. In public cloud, click the link to Remove from VDC and the Delete button.
