In a method for managing shared Ethernet adapters in a virtualized computer environment, a computer programmed with a hypervisor program receives a first request from a virtual client to transmit data. In response to receiving the first request, the computer programmed with the hypervisor program selects a first active virtual server from a first plurality of concurrently active virtual servers of the virtualized computer environment. The computer programmed with the hypervisor program copies the data from a memory of the virtual client to a trunk adapter of a first shared Ethernet adapter of the selected first active virtual server.
