I'm not sure how that would work... if the guest is in suspended animation mode, how would it execute commands? CP would have to be involved in some way because it's the only thing that's awake the entire time. The idea of going into suspended mode (have the kernel write the entire VM state, including memory contents, to disk, log off, and then resume from the suspended image) might be an interesting variation to explore, though -- especially if combined with a Linux IPL from a NSS. The initrd from the NSS IPL could look for a "suspend" file, and if it found one, load it back into RAM and jump back into it. That would use a lot of disk space, which might make it impractical for ECKD-only systems, but it would let you do what you want reasonably safely. Me, I'm not terribly comfortable with it -- I've lost too much data to suspend-mode on laptops running Windows to feel safe with it -- but other people seem to swear by suspending their laptops. YMMV. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
