This page describes how to view and manage networks at the virtual datacenter level, and manage IP addresses of public networks and change the default network of a virtual datacenter.

Privilege: Manage virtual network elements

Virtual datacenter networks

To view the networks available to a virtual datacenter, open Virtual datacenters view, select the virtual datacenter and click on the Network tab.

  • 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 VirtualDatacenterResource 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:
    • 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)

Manage private networks

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

Create a private network

To create a private network in your virtual datacenter, click the  button  and complete the form below.

Create a private network

Button

Action

Name

Name of the network (VLAN). The name can contain up to 128 characters

IPv6Select checkbox for IPv6 network
NetmaskNetwork mask with an integer value of between 16 and 30

Network Address

Private address range of the network

Gateway

Gateway of the VLAN. Must be an IP within the range of the network address and mask

Primary DNS

The primary DNS

Secondary DNS

The secondary DNS

DNS suffix

The DNS suffix

Excluded from firewallSelect Excluded from firewall to define a network where VM firewalls will not apply

Static Routes

Select Define to create static routes. See Configure Static Routes

Default network

Make this network the default network, replacing the existing default network.

You can configure static routes when you create or edit a VLAN. However, you should check with your systems administrator about when changes to static routes may be received by your VM.

Field

Description

Example

Netmask

Destination network mask

255.255.255.0

Network ID

Destination network or host

1.1.1.0

Gateway IP

Strict network

 

Non-strict network

FieldDescription

Name

Name of the VLAN. The name can contain up to 128 characters

IPv6Select checkbox for IPv6 network
StrictIPv6 only. If you select Strict, Abiquo will automatically generate the network address (ULA) and also the IP addresses. If you do not select strict, you can enter the network address and IP addresses.
NetmaskNetwork mask of 48, 56 or 64.

Network Address

Private address range of the network. Only for non-strict networks

Primary DNS

The primary DNS

Secondary DNS

The secondary DNS

DNS suffix

The DNS suffix

Default network

Make this network the default network. In a datacenter, this will override the existing default network

Public cloud

When you onboard from public cloud, if the provider supports networks, then the platform will onboard private networks, including details of IP addresses not used by VMs. You can synchronize these networks.

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

When creating a custom private network in AWS, you can choose the Availability Zone. Availability Zones enable users to deploy VMs separately, with high availability. You can deploy in an availability zone by assigning a private IP address in the network belonging to that Availability Zone.

Add IPs to private networks in datacenters

To create new IP addresses in your private network, click the Add button in the top right-hand corner of the Private IPs page. You can also create IPs automatically, directly in the Edit VM popup.

To create a range of IP addresses, 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 private networks in environments with reserved ranges, the platform will display the available ranges and indicate with a green arrow if the IP address is within the available range.

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.

Delete IPs

To delete IP addresses, select the network, then select the IP addresses and click the delete button. The platform will delete only the IP addresses that are not in use, which means not attached to a VM, or not purchased by the enterprise.

Edit a private network

To edit a private network, select the network, then click the Edit button  above the Networks list:

You can change the network name, gateway, DNS settings, and make the network the new default for this virtual datacenter.

Changes will apply to all VMs deployed after you click Save.

Delete a private network

You can delete a private VLAN if no VMs are using its IPs and it is not the default network. To delete a private VLAN, select it and click the Delete button  above the Networks list. 

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 defualt, when creating or editing the network, select the Default network checkbox. The new default network will apply to all VMs deployed after you set it.  

If you set a public network as the 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. 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

In public cloud, when you synchronize your virtual resources, the platform will synchronize existing floating IP addresses. You can also obtain these IP addresses and assign them to your 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.

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.
