To suspend a UML instance, at the prompt use "stop" and "go". I'm not at all sure you can gdb the UML instance meanwhile... but especially it will suspend any I/O you can do, and I think every process inside the UML instance, including gdb. > Does swsusp work under UML? :) Maybe, Nigel Cunningham, the developer of Swsusp 2 come by sometimes on this list. For swsusp, I don't know at all what would be needed. In the archives there was also an announce for a separate project for UML only to implement suspending in a UML-specific way (it was meaningful, but I don't remember about it, even because they wanted to run their own mainling list). -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
