Hello! Personally, as many may know, Ubuntu Lucid 10.04 have the Linux and the KVM with support for KSM enabled, look:
mart...@tcmc-air:~$ lsb_release -ra No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu lucid (development branch) Release: 10.04 Codename: lucid mart...@tcmc-air:~$ grep KSM /boot/config-`uname -r` CONFIG_KSM=y mart...@tcmc-air:~$ cat /sys/kernel/mm/ksm/run 1 mart...@tcmc-air:~$ cat /sys/kernel/mm/ksm/max_kernel_pages 125721 The KSM allows us to increase the density of virtual machines per hypervisor. See the following news: http://blog.dustinkirkland.com/2010/02/ksm-now-enabled-in-ubuntu-lucid.html http://events.linuxfoundation.org/lc09d22 http://www.linux-kvm.com/content/using-ksm-kernel-samepage-merging-kvm My questions are: 1) The Eucalyptus (eucalyptus-nc?) can "see" that the KSM is acting and thus, be able to start more instances than normal (without KSM) that the hypervisor (Linux + KVM + KSM) will manage the memory behind the scenes? 2) The Eucalyptus, knowing that there is the KSM acting at the nodes, it can try to start the same EMI always on the same hypervisor... Using more and more the KSM feature... Where this control can be done? Within the plugin that controls where the instances will be started? Thanks! Thiago
