This section describes the VLAN Network configuration for the Abiquo Platform.
The Service Network is a VLAN network that includes the following virtual network types:
Virtual machines on internal private networks can only communicate within the virtual datacenter. A virtual gateway can be used for communication outside the virtual datacenter. Virtual machines on public, external and unmanaged networks can communicate outside the virtual datacenter. VLAN tags should be assigned by the Network Administrator and entered into Abiquo for each external, public and unmanaged network.
Abiquo management of the service network has two main aspects:
Do these steps for the following hardware to configure the service network.
After the Network Administrator has configured the physical networks as described above, configure the Service Network VLAN tags in Abiquo.
The following screenshots show the configuration of an example scenario in Abiquo.
This is an example to show the GUI functionality and this configuration is not supported by Abiquo.
In this example, only one network service type is used.
Create a public network in Abiquo using the first public IP range you have purchased for your datacenter and a configured VLAN tag (in our example tag 2).
After purchasing more public IPs for the datacenter, add a second public VLAN, also with the public VLAN tag (in our example, tag 2).
Create an external network with a configured VLAN tag (in our example, tag 3)
Create an unmanaged network with a configured VLAN tag (in our example, tag 4)
Create a rack with reserved VLAN tags. In our example, tags 2 to 6 are reserved for the public, external, unmanaged networks and future networks of these types.
When we deploy the first virtual machine, a private network is created with the first free VLAN tag (in this case, tag 7)
The default Service Network configuration has one virtual switch or NIC per Host. All of the vNICs of virtual machines deployed on the hypervisor are attached to the same virtual switch or NIC. It was also connected to all the VLANs in the Infrastructure. The following diagram shows only one network service type (Service Network), which is the default configuration in Abiquo 2.4.
The new Network Service Type feature allows you to use multiple virtual switches or NICs in each hypervisor. The 'Network Service Type' is a 'tag' for identifying the networks your virtual switches or NICs will attach to. The infrastructure administrators tag each virtual switch or NIC to enable it and identify its network in Abiquo. Then administrators of public, external and unmanaged VLANs also tag each of these VLANs with a network service type. When users deploy virtual machines, Abiquo will attach their vNICs to the virtual switches or physical NICs with the tags matching their VLANs. The following diagram shows this approach.
For private networks isolated within a virtual datacenter, multiple VLANs can use the same IP address range, i.e. every customer can create its own network name (VLAN) with network address 192.168.0.0/24. This will create different VLANs but the same IP Network. Network administrators should be aware of this default configuration. For example:
