Embodiments include a method of organizing communications channels associated with virtual functions of a single root input and output virtualization (SR-IOV) adaptor. The method includes organizing a first coupling channel according to a first channel path identifier bound to designated communications over a first virtual function of the SR-IOV adaptor allocated according to first virtual function resources that support the first coupling channel. The method also includes enabling access to the first coupling channel to a first guest operating system. The method also includes receiving a teardown command associated with the first coupling channel. The method further includes initiating a reset of the first virtual function that deallocates the first virtual function resources associated the first virtual function.
