OpenVZ Question:

Do you know how to over-commit the memory in OpenVZ?

Answer:

To over-commit the memory in OpenVZ few pages has to be modified like vmguarpages and oomguarpages that provides the resource management configuration files. Out of these vmguarpages provides the maxium memory a container can have and oomguarpages provides the maximum memory that is being consumed by the processes. These are used to set the limit. Limit also has some files like privvmpages that puts an upper limit on container memory. It is also used for non-swappable kernel memory. By using these functions over-commitment of the memory can be done by using OpenVZ.
