Software defined networking
Abiquo supports software defined networking (SDN) through integrations with network managers such as OpenStack Neutron and VMware NSX, providing SDN and firewalls and load balancers in private cloud datacenters or regions.
Typically, the administrator configures the network manager in Abiquo with a set of reserved IPs in a public or external VLAN. The network manager is configured to manage private VLANs on a virtual datacenter level, with a number of reserved IPs in each private VLAN for router, gateway, and load balancers. The network manager can also assign an external or public IP from the reserved range to enable VMs on the private VLAN to access the outsider world, or for a public load balancer address, for example.
Abiquo will connect VMs to the private VLANs, and from here they can have automatic access to other networks through the external or public IP assigned by the network manager.
DHCP or guest setup
To configure VMs in virtual networks (private, external and public), you can use the Abiquo DHCP server or supply your own. Abiquo creates leases and sends them to the DHCP Server over the management network using the OMAPI protocol, when the user deploys the virtual machine, and before it powers on. The lease contains the MAC address that Abiquo assigned to the VM and the IP address that the user or Abiquo selected. If no DHCP server is found, Abiquo will inject the network configuration using guest setup. See Guest setup
