A computer implemented method includes receiving a request to access a configuration space that is associated with a virtual function. The request may include a configuration space address and a root complex identifier. The computer implemented method may include identifying a root complex based on the root complex identifier. The computer implemented method may also include selecting a slot that is associated with the root complex. The slot may be capable of coupling a hardware input/output adapter to the root complex. The computer implemented method may further include determining whether the configuration space address is associated with the selected slot. The computer implemented method may include accessing the configuration space using an access mechanism in response to determining that the configuration space address is associated with the selected slot.
