Abstract

Techniques are provided for desktop streaming over wide area networks. In one embodiment, a computing device comprises pivot logic that is configured to be executed during a first boot of an operating system on a computing device as a pivot process that is the only process running when performing modifications to a file system on the computing device. During execution, the pivot process replaces a current set of files in the file system with a new desktop image that represents a complete view of the file system. The desktop image includes a prefetch set of files, but other files in the desktop image are represented by file metadata. The prefetch set of files includes a smallest subset of files that is needed to boot the computing device without requiring retrieval of additional files. During execution, the pivot process terminates the first boot and to invoke a second boot that is executed based on the prefetch set of files included in the new desktop image.

Claims24

Dependent claims

A computing device comprising:

one or more processors;
one or more storage media coupled to the one or more processors;
pivot logic stored in the one or more storage media and executable by the one or more processors, wherein the pivot logic is configured to cause the one or more processors to:
execute a pivot process during a first boot of an operating system (OS) on the computing device, wherein the pivot process is the only process running when performing modifications to a file system on the computing device, wherein during execution the pivot process causes the one or more processors to:
replace a current set of files in the file system with a new desktop image, wherein the new desktop image presents a complete view of the file system;
wherein a prefetch set of files is included in the new desktop image, but other files are represented in the complete view of the file system by file metadata that is included in the new desktop image;
wherein the prefetch set of files includes a smallest subset of files, in the new desktop image, that is needed to boot the computing device without requiring retrieval of additional files;
terminate the first boot and invoke a second boot that is executed based on the prefetch set of files included in the new desktop image.

5 more elements

A computer-readable non-transitory storage medium storing one or more sequences of instructions comprising pivot logic instructions which cause one or more processors to:

execute a pivot process during a first boot of an operating system (OS) on a computing device, wherein the pivot process is the only process running when performing modifications to a file system on the computing device wherein during execution the pivot process is configured to cause the one or more processors to:
replace a current set of files in the file system with a new desktop image, wherein the new desktop image presents a complete view of the file system;
wherein a prefetch set of files is included in the new desktop image, but other files are represented in the complete view of the file system by file metadata that is included in the new desktop image;
wherein the prefetch set of files includes a smallest subset of files, in the new desktop image, that is needed to boot the computing device without requiring retrieval of additional files;
terminate the first boot and invoke a second boot that is executed based on the prefetch set of files included in the new desktop image.
