Live Memory Recovery Using a Pluggable Memory Module

Systems and techniques for live memory recovery using a pluggable memory module are described herein. It may be detected that a spare memory module has been inserted into a computing device based on a signal transmitted from the spare memory module. The spare memory module may be initialized. A dynamic random-access memory (DRAM) module of the computing device may be identified that is predicted to fail. Freeze instructions may be transmitted to a virtual machine manager to pause virtual machines executing on the computing device. Memory data may be transferred from the DRAM module to the spare memory module. Memory addresses may be remapped from the DRAM module to the spare memory module. Unfreeze instructions may be transmitted to the virtual machine manager to resume the virtual machines executing on the computing device.
