Anatomy of Linux Kernel Shared Memory

Posted by kdawson on from the culture-by-another-name dept.

An anonymous reader sends in an IBM DeveloperWorks backgrounder on Kernel Shared Memory in the 2.6.32 Linux kernel. KSM allows the hypervisor to increase the number of concurrent virtual machines by consolidating identical memory pages. The article covers the ideas behind KSM (such as storage de-duplication), its implementation, and how you manage it.

    Not an "operating system" graduate course.

    Is it a slow news day or is the Slashdot crew too busy
    snorting the leftover cocaine from the
    Goldman Sachs Party?

    I think your problem is you just tried Linux by itself. GNU/Linux is an operating system.

    Wrong. GNU/Linux is the Linux kernel + GNU userland. You still have SysV vs. BSD init among other things to consider.

    Debian, Ubuntu, RedHat, Gentoo, etc. etc, are operating systems.
