hostfs

VIRTUTECH CONFIDENTIAL Previous - Up - Next

Provided by: hostfs
Class Hierarchy: conf-object → log-object → hostfs
Interfaces Implemented: log_object, io_memory
Description: The hostfs device is used in conjunction with a target OS module to allow the simulated machine to access the filesystem of the host machine. In order to work, the hostfs-device needs to be mapped into a specific location in the physical memory space. This address is target OS and architecture dependent. Diskdumps from Virtutech already have the target OS module installed (where supported).

Commands

info	print information about the device
root	set or show the hostfs root directory
status	print status of the device

<hostfs>.info
Synopsis: <hostfs>.info
Description: Print detailed information about the configuration of the device.

<hostfs>.root
Synopsis: <hostfs>.root [dir]
Description: Set the host directory that is visible to the simulated machine to dir. If no directory is specified, the current root directory is shown. Changes may not take effect until next the file system is mounted.
