Abstract
A method, system and program product for managing assignment of virtual physical addresses. The method includes requesting, using a services function provided by a virtual machine operating system, a MAC address assignment for a real device and searching, in a MAC assignment table created and stored within a virtual memory space, to determine whether or not an explicit MAC address is assigned to the device. If an explicit MAC address is determined to be assigned to the device, retrieving the explicit MAC address upon verifying that the MAC address is not in use by another device and forwarding, using the services function, the explicit MAC address retrieved for assignment to the real device. If an explicit MAC address is not assigned to the device, retrieving an available MAC address from a MAC address pool table and forwarding the available MAC address retrieved for assignment to the real device.
