Abstract
Mechanisms are provided for an I/O virtualization management partition (IMP) to control the shared functionality of an I/O virtualization (IOV) enabled I/O adapter (IDA) through a physical function (PF) of the IOA while the virtual functions (VFs) are assigned to client partitions for normal I/O operations directly. A hypervisor provides device-independent facilities to the code running in the IMP and client partitions. The IMP may include device specific code without the hypervisor needing to sacrifice its size, robustness, and upgradeability. The hypervisor provides the virtual intermediary functionally for the sharing and control of the IOA's control functions.
