A system (600) and method (500) for virtualizing hardware acceleration resources with a guaranteed quality of service is described. In one aspect, the system (600) implementing the method (500) creates virtual hardware accelerators (308A, 308B, 308C) on a hardware accelerator unit (104) coupled to a host server or a host processing unit (102). Address registers and device configuration address registers are assigned to each virtual hardware accelerator (308A, 308B, 308C). Requests for executing applications are received from the virtual hardware accelerators (308 A, 308B, 308C) and translated into hardware accelerator resource requirements. The hardware accelerator resources are partitioned and allocated to the virtual hardware accelerators (308A, 308B, 308C). The hardware accelerator resources (314, 316, 318) are monitored for the usage of each virtual hardware accelerator (308A, 308B, 308C).

Quality of service parameters are enforced for each virtual hardware accelerator (308 A, 308B, 308C) by dynamically monitoring and modifying resource allocation based on the comparison and maintaining address space isolation between the virtual hardware accelerators.
