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 a virtual datacenter
  2. Go to NetworksPrivate → select a private network
  3. On the Private IPs page, click the add + button and enter details

Or you can add an IP directly to a VM. To do this:

  1. Go to Virtual datacenters → Edit VM → Network
  2. Click the add + button and enter details (or drag the Auto-generated IP label into the Network pane)

Enter the Number of IPs to create and the From IP address (the first in the range). The From 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, which are 30, 33, and 34 and then you request 3 new IPs from The new IPs created should be as follows: 31, 32, 35. 
IP Addresses

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 a From IP address manually.

Edit a private network

To edit a private network
  1. Go to Virtual datacenters → select a virtual datacenter → Network
  2. Select the network
  3. Click the pencil edit button below the Networks list
  4. You can change the network Name, Gateway, DNS settings, and optionally make the network the new default for this virtual datacenter.
  5. 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 → select a virtual datacenter → NetworkPrivate
  2. Select the network and click the delete button below the networks list. 

Display onboarded external networks

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

Privileges: Manage virtual network elements, Access external networks tab, Manage external network elements

To display onboarded external networks

  1. Go to Virtual datacentersNetwork → 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 the default network for a virtual datacenter

Each virtual datacenter requires a default network. If you deploy a VM without assigning a NIC, the platform will add one from the default network. You cannot unselect the default network, instead you must assign a new default network to replace it.

To set a network as the default, you will require privileges to access this network in the virtual infrastructure.

Privileges: Manage virtual datacenter network elements, Access public network tab, Manage public network elements, Access external network tab, Manage external network elements

To assign a network as the default for a virtual datacenter do these steps:

  1. Go to Virtual datacenters → select virtual datacenter → Network → network type, e.g. Private
  2. Create or edit a network
  3. Select the Default network checkbox 
    • This default will override the platform default network and any network set for the enterprise in the datacenter
    • The new default network will apply to all VMs deployed after you set it
    • For a public network that is the virtual datacenter default, 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. 

Privilege: Manage public IPs, Access public networks tab, Manage public network elements

To add new public IP addresses to your virtual datacenter:

  1. Click the + Add button on 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. To filter your search, enter an IP address or Network name in the Search 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

You can also reserve public IPs directly from the Edit VM dialog.

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.

The provider may charge for public 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. Remember that your provider may also limit the number of public IP addresses that you can use per virtual datacenter.

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

Privileges: Manage virtual network elements, Manage floating IPs, Access public networks tab, Manage public network elements

  1. Go to Virtual datacenters → Select a public cloud virtual datacenter → Network → Public
  2. On the Allocated public IPs page, click the + add button
  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, the platform will display the public IP address and you can add it to your VM.

To obtain a public IP directly for a VM, click Purchase public IPs.

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:

Privileges: Manage virtual network elements, Manage floating IPs, Access public networks tab, Manage public network elements

  1. Go to Virtual datacenters → select a public cloud virtual datacenter → Network → Public
  2. Click the double arrow synchronize public IPs button (beside the + add button)

Release a reserved public IP address

You can release a public IP if it is not assigned to a VM.

In private cloud, to release a public IP that belongs to a public network, select the IP in the IP list and click the delete button.

In public cloud, click the link to Remove from VDC and then click the delete button.

Limit Public IP bandwidths for a VDC

You can use Quality of Service (QoS) traffic shaping parameters to limit the bandwidth for each public IP in a virtual datacenter.  

This feature applies to public IPs in infrastructure and managed by NSX in vCenter and vCenter clusters.

Privileges: Manage public bandwidth limit

When you upgrade the platform or create a virtual datacenter, the public IPs bandwidth limit is disabled. To enable the limit for the public IPs of the VDC, edit the bandwidth limit. 

To edit the bandwidth limit and enable it in the platform:

  1. Select the virtual datacenter and go to Network → QoS
  2. Click the pencil edit button 
    1. To set the bandwidth limit in a specific direction, select the Enabled checkbox for that direction
    2. Set QoS values to apply to each public IP in virtual datacenter. This bandwidth will be set for each public IP in the virtual datacenter.

    EnabledTo enable traffic shaping in a specific direction, select this checkbox
    AverageThe average amount of bandwidth, in bits per second, that each public IP in the virtual datacenter can use
    PeakThe maximum bandwidth in bits per second that each public IP in the virtual datacenter can use
    Burst sizeThe amount of data that can be transmitted at the peak bandwidth rate in bytes. A burst bonus accumulates when traffic is below the Average value and this bandwidth can be used for bursts

To register changes that were made outside the platform, save existing public IP bandwidth values. In the API, to register changes, send a POST request with the existing values.

Reserve private IPs

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 and the reason beside the IP reserved addresses.
