Abstract: Interacting with an external environment of a segmented virtual machine is disclosed. An indication that a communication with an external environment is desired is received. It is determined whether the communication can be initiated directly from a core virtual machine of the segmented virtual machine without initiating the communication from a shell virtual machine of the segmented virtual machine. An attempt to initiate the communication is made based as at least in part on the determination.

Abstract: Providing data to an application running on a segmented virtual machine (VM) is disclosed. Providing data includes opening an interface between the segmented VM and an external data source, transferring data from the external data source to an interface buffer, transferring a first selected amount of data from the interface buffer to a shell VM buffer, transferring a second selected amount of data from the shell VM buffer to a core VM buffer, and providing portions of the data from the core VM buffer to the application in response to read requests from the application.

Abstract: Accessing data comprises executing a set of computer instructions in a first environment, wherein the first environment has limited addressing capability to address memory up to a size limit, specifying a set of data in a memory space of a second environment, wherein the memory space has a size that exceeds the size limit, and accessing the set of data from the first environment using the limited addressing capability.
