Method and system for creating a virtual file system from a unified archive

A system for creating a VE in an NGZ from a UA, comprising:

• a processor;
• a host GZ, executing on the processor, and comprising the NGZ;
• the UA, wherein contents of the UA are accessible via a VFS comprising an index;
• a zone manager, located in the host GZ, and configured to:
• receive an instruction to create the VE within the NGZ using an image file of the VE, wherein the image file is located in the UA;
• access the image file using a guest VFS located within the NGZ;
• and
• create the VE from the image file.
• a VFS daemon, located in the host GZ, and configured to:
• identify a directory of the VFS corresponding to guest data of the UA, wherein the guest data is associated with the NGZ and comprises the image file;
• create a copy of the index comprising only portions of the index corresponding to the guest data;
• and
• create, based on the copy of the index, the guest VFS within the NGZ, wherein the guest VFS makes accessible only the contents of the UA corresponding to the guest data.

A non-transitory computer readable medium comprising executable instructions for:

• receiving an instruction to create a virtual environment (VE) within a non-global zone (NGZ) of a global zone (GZ) using an image file of the VE, wherein the image file is located in a UA, and wherein contents of the UA are accessible via a virtual file system (VFS) comprising an index;
• identifying a directory of the VFS corresponding to guest data of the UA, wherein the guest data is associated with the NGZ and comprises the image file;
• creating a copy of the index comprising only portions of the index corresponding to the guest data;
• creating, based on the copy of the index, a guest VFS within the NGZ, wherein the guest VFS makes accessible only the contents of the UA corresponding to the guest data;
• accessing the image file using the guest VFS;
• and
• creating the VE from the image file.
