A resource management node is provided including a processor and a memory. The memory is coupled to the processor and comprises computer readable program code that when executed by the processor causes the processor to perform operations including creating a recovery virtual machine (VM) for a primary machine for each of a primary machines. The recovery VM is stored in a cache file in a kernel of an operating system. The data in the cache file is stored in a format readable by a virtual hypervisor. The processor is further caused to perform operations including providing the recovery VM from the cache file in the kernel of the operating system upon request when the primary machine fails without conversion of the data in the cache file.
