Abstract: A computer-implemented method for live migration of a logical dedicated host and virtual machines (VMs) associated therewith from a first physical server to a second physical server, in accordance with one aspect of the present invention, includes, in response to receiving a request to migrate a logical dedicated host from the first physical server, creating a clone of the logical dedicated host thereby creating a clone dedicated host. The clone dedicated host is provisioned on a second physical server. VMs are migrated from the logical dedicated host to the clone dedicated host. The migration is transparent such that user operations being performed on the VMs continue uninterrupted during the migration. In response to completion of the migrating of the VMs to the clone dedicated host, the logical dedicated host is caused to be de-provisioned from the first physical server.

Abstract: A method of controlling fuel injection in a dual fuel engine system includes determining, with a first controller, a diesel injection pulse indicative of a first amount of diesel fuel to be injected into a combustion chamber of the engine and a first timing at which the first amount of diesel fuel is to be injected. The method also includes determining, with a second controller, a combined injection pulse based on the diesel injection pulse. The method further includes injecting the second amount of diesel fuel and the third amount of natural gas into the combustion chamber in accordance with the combined injection pulse. In such a method, injection in accordance with the combined injection pulse results in a combustion event characterized by a second combustion characteristic substantially equal to a first combustion characteristic associated with the diesel injection pulse.
