This paper is intended to provide an abstract and transparent layer for virtual machines (VM) to access reconfig-urable resources. The underlying infrastructure of partial reconfiguration management is hidden from the VMs. D-PR accelerators are presented as virtual devices, which are universally mapped in each VM space as ordinary peripherals. The framework automatically allocates D-PR resources dynamically according to a preemptive allocation mechanism. The evaluation of DPR management overheads demonstrates that our mechanism is implemented with low latency.
