Abiquo manages vCenter as a master hypervisor, which can be added through the UI.
You can set Abiquo configuration properties to configure the vCenter as required, as well as the DVS and optional NSX.
After you create a rack, you can add a hypervisor, selecting vCenter as the hypervisor type. Then you can select the ESXi hypervisors of the vCenter to add to the platform and configure them.
Abiquo automatically detects the clusters of the ESXi hypervisors and adds them to the appropriate Abiquo racks.
