Claim Text:
1. A method comprising: determining that a first server, which hosts a virtual machine, is in a first subnet and that a second server, which hosts a replica copy of the virtual machine, is in a second subnet; determining that the virtual machine has a fixed network address; in response to determining that the first server and the second server are in different subnets and that the virtual machine has a fixed network address, determining, at a control service, network adaptor configuration information for a network adaptor of the replica copy based, at least in part, on the first and second servers being in different subnets; mounting, at the second server but outside of a child partition corresponding to the replica copy of the virtual machine, a virtual storage drive associated with the replica copy of the virtual machine; copying the network adaptor configuration information to the virtual storage drive; setting an injector tool to configure a virtual network adaptor of the replica copy with the network adaptor configuration information in response to start up of the replica copy of the virtual machine for switchover from the virtual machine to the replica copy of the virtual machine; and unmounting the virtual storage drive after configuration of the virtual network adaptor.
