Some embodiments of virtualization management using a centralized server have been presented. In one embodiment, a centralized server obtains metadata of an operating system and information on provisioning computing resources from a software vendor. The centralized server is deployed within an internal network of a customer of the software vendor, where the internal network further includes a set of at least one physical machine. The centralized server may further generate a graphical user interface to allow users of the centralized server to manage a set of virtual machines running on the set of at least one physical machine. The set of virtual machines may include at least one virtual host and at least one virtual guest.
