Depends on the kind of virtualization. As you're on Linux, you could use OpenVZ: it has similar characteristics as chroot - it just separates namespaces (eg. network interfaces, pids, etc) and allows different limits (eg. maxprocs, maxfiles, maxmem, ...) on per-VZ basis. BTW: my current customer already consolidated multiple formerly dedicated mysql servers (in mass hosting) onto one metal (now we're building a system which allows moving individual databases around in the cluster w/o being visible to the customer ...). The same should be easily possible w/ PostgreSQL and other RDBM'es. cu -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service - http://www.metux.de/ --------------------------------------------------------------------- Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ ---------------------------------------------------------------------
