Abstract
A method, system and computer program product for efficiently utilizing a virtual file system cache across cloud computing nodes. A determination is made as to which hypervisors will be able to share all or a portion of the memory in its cache module (look-aside cache) to become a hypervisor in a 'pool of hypervisors' based on the workload of the virtual machines run by the hypervisor. All or a portion of the memory in the cache module in each hypervisor in the pool of hypervisors that is available to be utilized by other virtual machines is allocated to form a 'shared cache module' to be utilized by virtual machines run by the pool of hypervisors. In this manner, the look-aside cache available to the hypervisor will be utilized more effectively since any available memory can be utilized by other virtual machines running on different hypervisors on different cloud computing nodes.
