Hibernation is usually considered as an obsolete feature for laptops, but it can still provide significant benefits in many different scenarios, if it can be made to work reliably and efficiently. The main bottleneck of hibernation is the cost of I/O, both at hibernation and resume time, but it is possible to reduce this cost using opportunistic memory reclaiming techniques. Canonical has been actively experimenting hibernation in cloud computing and virtualized environments. In the process we had the opportunity to experiment some improvements and learn surprising lessons. This session shares some technical details of the solutions that we developed, the lessons learned and the results that we found.
