Unmanaged NetworksIn private cloud datacenters, unmanaged networks are a special type of external network : Abiquo does not manage the IP addresses for virtual machines attached to these networks. You must allocate these IP addresses outside of Abiquo. You can assign the IP address to virtual machines using the corporate DHCP server or by manually entering configuration with ifconfig in a shell, for example. Unmanaged networks can use public or private IP address ranges and they can be shared across one or more virtual datacenters. 

The Abiquo DHCP server does not allocate IP addresses to virtual machines on unmanaged networks. And the virtual machines on unmanaged networks do not communicate with the Abiquo DHCP Server, so they will not receive static routes set using DHCP in Abiquo.

Administer unmanaged networks on the External network tab in Infrastructure view.

View Unmanaged Networks

Unmanaged networks are displayed with  (unmanaged) beside their name in the network list on the External networks page.

If you click on an unmanaged network in the list on the External networks tab, Abiquo will only display the gateway address and any addresses you registered, for example, during virtual machine capture. 

Note

The cloud administrator is responsible for the proper administration of IP address ranges and VLAN tags.

From these screens the cloud administrator or other authorized user can perform these actions:

Create VLANs for Unmanaged Networks

Before you begin:

...

with IP addresses that are allocated outside of the platform. 
Abiquo does not manage the IP addresses for VMs attached to these networks.

Before you begin, obtain the details of your network in the infrastructure, including the VLAN tag, network address, and gateway.

To create unmanaged networks do these steps:

  1. In Infrastructure view, go to the external networks page of the Network tab
  2. Click the add button at the top of the External networks page and complete the form
    1. External and unmanaged networks are created with the same form. Mark the Unmanaged checkbox to create an unmanaged network
    2. You must enter the network and the gateway for IPv4 networks
Info
titleTag Availability Info*

The check availability button will check if the VLAN tag is available for all the racks of the datacenter. An unmanaged VLAN can be used on any rack and should be tagged in the same way on all racks. Tags in use by other VLANs will display a yellow warning signal but they may be used; only invalid tags will be rejected, with a red signal.

IPv4 networks

...

No static routes using DHCP in unmanaged networks

Machines on unmanaged networks will not receive static routes by DHCP because they do not connect to the Abiquo DHCP Server.

IPv6 networks

Edit Network Information

To edit the Network Information for an unmanaged VLAN, select it in the VLAN list on External page. Then click the edit  button at the top of the NETWORKS list.

Add IP Addresses

You can add IP addresses of NICs in unmanaged networks for display in Abiquo. These IP addresses are for display only - Abiquo does not allocate them or manage them. You can add display IP addresses during the capture process (using GUI or API) or at any time (using the API).

Screenshot: adding IP addresses during the capture process. First select the unmanaged network with the same VLAN tag as the hypervisor network used by the VM. Then enter the IP address for the VM. As mentioned above, this is for display purposes only. As for all unmanaged networks, you must assign the IP address to the virtual machine outside of the platform.

  3. On the External page, click the + add button  

  4. Complete the dialog as described, marking the Unmanaged checkbox.

    Image Added


Field

Value

Name

The name of the unmanaged VLAN with up to 128 characters

IPv6

To create an IPv6 network, select this checkbox

Strict

For IPv6 networks only. If you select Strict, Abiquo will automatically generate EUI64 IP addresses and you will not be able to manually generate them

Address

The network address of the VLAN

Netmask

The network mask in CIDR format

Gateway

The gateway of the network. It must be an IP address inside the range defined by the network address and the network mask

Tag

The VLAN tag to use for this VLAN

Check

Check tag availability for all racks of the datacenter. You should define a VLAN with the same tag on all racks.
Green = available, Yellow = in use, Red = unavailable

Network service type

Select the Network Service Type, which represents a network interface on the hypervisors

Unmanaged

Select to create an unmanaged network, when you will manage IP addresses outside Abiquo

Enterprise

Select the owner enterprise that will use the unmanaged VLAN

Device

Not used for unmanaged networks

Primary DNS

The IP address of the Primary DNS server

Secondary DNS

The IP address of the Secondary DNS server

DNS suffix

The default DNS suffix

Restricted

Mark this checkbox to create a Restricted network.
To work with IPs in a restricted network, users require the privileges to Attach NICs in restricted networks and/or Detach NICs from restricted networks

Excluded from firewall

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

Static routes

Not used for unmanaged networks

To display IP addresses of NICS in unmanaged networks, add them:

  • using the API; or

  • during VM capture using the UI or API 

For strict IPv6 networks, you cannot add IP addresses.
However, the platform retrieves the MAC address from the hypervisor and uses that to generate an IPv6 address for display. The addresses displayed in Abiquo for strict IPv6 networks
The display address should be the same as those the address allocated by the router system.

View the IP List

On the right side of the screen, in the External IPs pane, you will see details of the IPs added for the selected unmanaged VLAN. Click in the header of a column to sort by that column, use the Search button to filter the results by any field and navigate through the pages with the page scroll.

Delete Unmanaged VLANs

To delete an unmanaged VLAN, select it in the VLAN list on the External tab and press the delete button Image Removed and the unmanaged VLAN will be deleted.
