The invention provides a data processing method and device which are used for solving the problem existing in the prior art that when a virtual machine carries out memory dirty logging, the virtual machine frequently quits to a Hypervisor, and the internal service of the virtual machine is interrupted. The data processing method is applied to a first physical machine in a virtual machine system, a first virtual machine operates on the first physical machine, the virtual machine system also comprises a second physical machine, a second virtual machine operates on the second physical machine, and the first physical machine comprises a central processing unit (CPU) and a virtual machine hypervisor (Hypervisor). The data processing method comprises that under the preset condition, when the first physical machine carries out memory write operation, a first address and a second address are obtained, a mapping relation between dirty logging bitmaps corresponding to the first address and the second address exists, the corresponding bit of the first address in the corresponding dirty logging bitmap of the second address is determined in dependence on the mapping relation, and the corresponding bit position is set.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a data processing method and device. Background technique [0002] With the rapid development of computer technology, more and more companies and research institutions have begun to pay attention to the energy consumption and resource utilization of computers, and cloud computing is one of the key computing models. Cloud computing abstracts all computers into specific computing resources, and then provides these computing resources to users instead of directly providing one or more computers. The biggest advantage of this model is that users can apply for resources according to their actual needs, avoid unnecessary waste of resources, and improve resource utilization. [0003] Server virtualization technology is a key technology based on the infrastructure layer in cloud computing. By virtualizing physical servers, it is possible to deploy multiple virtual machine...
