Abstract: An intelligent virtual desktop infrastructure (iVDI) system is described. The system includes a first storage module having a processor, in communication with a hypervisor, and implemented by a volatile memory. The first storage module supplies a plurality of virtual machine operating systems (VMOSs) to the hypervisor. The hypervisor runs virtual machine (VMs) corresponding to the VMOSs. The systems also includes a VMOS management module configured to execute a first determination operation to determine if a usage of the first storage module has reached a preset storage limit. If yes, the VMOS management module selectively (a) initiate a deduplication operation directed to the plurality of VMOSs stored in the first storage module and (b) initiate a removal operation including removing at least one of the VMOSs from the first storage module and/or turning off at least one of the VMs running on the hypervisor.

Abstract: Systems and methods for dynamically allocating resources of virtual machines (VMs) using service level agreements (SLAs) and privilege levels of users. The system includes VM servers for executing the VMs. When a software application is to be executed on one executed VM on a VM server, a management device determines, from a first table, the privilege level of each executed VM based on the SLA, and then retrieves, from a second table, the resource allocation information for the software application to be executed using the privilege level of the executed VM. If, based on the resource allocation information, the resource of the VM server is determined to be unavailable for execution of the software application, one or more executed VMs having a lower privilege level on the VM server may be migrated to other VM servers to free up the resources.
