Linux KSM (memory de-duplication)

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream.

Code: Select all
echo "KSM pages shared: $(( $(cat /sys/kernel/mm/ksm/pages_sharing) * $(getconf PAGESIZE) / 1024 / 1024 ))Mb"
