Subject: [uml-devel] UML on SSI Cluster / UML live migration ?
Date: Wed, 24 Nov 2004 01:37:46 +0100 [thread overview]
Message-ID: <058201c4d1bd$d23e9f40$2000000a@schlepptopp> (raw)
Hello,
does someone know, what exactly prevents UML from working on SSI Cluster-Systems like OpenMosix ? I`m not sure, but i think I
remember it was because of missing OpenMosix-Feature to migrate Threads or Processes using SharedMem. I read a little bit about
OpenMosix today and found, that there seems to be such feature (now) : http://mcaserta.com/maask/
I would find it VERY useful to be able to run a bunch of UMLs on such a Cluster - e.g. for Loadbalancing and Failover purpose.
Currently i know of 2 Virtualization-Technologies, which can do "Virtual Machine Live Migration":
VMWare ESX Server AddOn "VMotion" (too expensive) and XEN`s "Live Migration" feature (Not yet ready for production usage, IMHO).
Any comments?
regards
Roland
PS:
This is not about "OpenMosix-UML" (the patch to make UML act as an OpenMosix Cluster) - it`s about running UML inside an OpenMosix
Cluster.
