Abstract
Systems and methods for data storage management technology that enables a guest module of a virtual machine to indicate an order in which a host module should write data from physical memory to a secondary storage. An example method may comprise: identifying, by a processing device executing a host module, a plurality of modifications to direct access excited (DAX) memory made by a plurality of direct access operations executed by a guest module of a virtual machine; determining, by the host module, an order of the plurality of modifications to DAX memory; receiving, by the host module, a synchronization request from the guest module; and responsive to the synchronization request, copying, by the host module, data from the DAX memory to a secondary storage in view of the order of the plurality of modifications.
