set-image-memory-limit [limit] [swapdir]
Limits the in-memory footprint of all image objects to limit megabytes. This only limits the memory consumed by image pages in memory. While this is typically a very large part of Simics's memory usage, other data structures are not limited by this command.
If limit is zero, the memory limit is removed. If swapdir is specified, it indicates a directory to use for swap files. If no argument is given, the current setting is displayed.
Simics sets a default memory limit at startup that depends on the amount of memory on the host system, generally about two-thirds.
