Fast restart of large memory systems

Abstract

Utilizing a storage replica data structure includes receiving, at a hyper-kernel running on a computing node in a plurality of interconnected computing nodes, an indication of an operation pertaining to at least one of a guest physical memory address or a stable storage address. A guest operating system is run on a virtual environment that is defined by a set of hyper-kernels running on the plurality of interconnected computing nodes. It further includes updating a storage replica data structure. The storage replica data structure comprises a set of entries. The set of entries in the storage replica data structure comprises associations among guest physical memory addresses, physical memory addresses, and stable storage addresses

What is claimed is: 
     
         1 . A computer system, comprising:
 a plurality of interconnected computing nodes, wherein a guest operating system is run on a virtual environment that is defined by a set of hyper-kernels running on the plurality of interconnected computing nodes; and   wherein based at least in part on receiving, by a hyper-kernel, an indication of an operation pertaining to at least one of a guest physical memory address or a stable storage address, the hyper-kernel updates a storage replica data structure, wherein the storage replica data structure comprises a set of entries, and wherein the set of entries in the storage replica data structure comprises associations among guest physical memory addresses, physical memory addresses, and stable storage addresses.
