Abstract
An embodiment of the invention is associated with a virtualized environment that includes a hypervisor, client LPARs, and virtual servers that each has a SEA, wherein one SEA is selected to be primary SEA for connecting an LPAR and specified physical resources. A first SEA of a virtual server sends a call to the hypervisor, and in response the hypervisor enters physical adapter capability information, contained in the call and pertaining to the first SEA, into a table. Further in response to receiving the call, the hypervisor decides whether or not the first SEA of the virtual server should then be the primary SEA. The hypervisor sends a return call indicating its decision to the first SEA.
