Abstract: A particular portion of a program which can be read from on-disk representations of the program as well as from memory images of the program is identified for use as a version discriminator. A first representation of the portion may be obtained from a first memory image of the program, corresponding to a first running instance of the program. The first representation may be compared to a second representation obtained at a development environment. Based on the results of the comparison, a particular version of the program corresponding to the first running instance may be identified. An indication of the particular version may be stored.

Abstract: An opportunistic hypervisor determines that a guest virtual machine of a virtualization host has voluntarily released control of a physical processor. The hypervisor uses the released processor to identify and initiate a virtualization management task which has not been completed. In response to determining that at least a portion of the task has been performed, the hypervisor enters a quiescent state, releasing the physical processor to enable resumption of the guest virtual machine.

Abstract: Based on source code analysis of an API-invoker program, an expendable set of source code sections of an API-implementer program is identified. The expendable set corresponds to operations which are not expected to be performed on behalf of the API-invoker program at a particular computing environment. An optimized binary version of the API-implementer program is generated, which does not include executable code corresponding to the expendable set. The optimized binary version is transmitted to the computing environment for deployment.

Abstract: An offloaded virtualization management component of a virtualization host receives an indication from a hypervisor of a portion of main memory of the host for which memory allocation decisions are not to be performed by the hypervisor. The offloaded virtualization management component assigns a subset of the portion to a particular guest virtual machine and provides an indication of the subset to the hypervisor.
