Patent ID: 7461080

Claim:
A machine-implemented method, comprising: establishing, in association with a global operating system environment (OSE) controlled by an operating system kernel instance, a first log device node; establishing, in association with a first virtual operating system environment (VOSE) of a plurality of VOSEs controlled by the operating system kernel instance, a second log device node; wherein one or more interfaces of the first log device node are associated with one or more first files located in a global file system tree; wherein one or more interfaces of the second log device node are associated with one or more second files located in a first subtree of the global file system tree; and wherein the one or more first files are not located in the first subtree; establishing a first log file at a location in the global file system tree, wherein the location is not within the first subtree; establishing a second log file at a location in the first subtree; executing, in association with the global OSE, a first process that reads data from the first log device node and writes at least some of the data from the first log device node into the first log file; and executing, in association with the first VOSE, a second process that does not read data from any log device node other than the second log device node and writes at least some of the data from the second log device node into the second log file; wherein, to the second process, a directory path of the second log file appears to be the same as a directory path of the first log file.
