The invention discloses a virtual machine disk synchronization method and device, equipment and a readable medium. The method comprises the following steps that a first virtual machine carries out disk IO operation; the first virtual machine management program obtains IO data, stores the IO data in a first virtual machine disk, and sends the IO data to the second virtual machine management program; in response to IO data received by the second virtual machine management program, storing the IO data in a second virtual machine disk; in response to storage of the IO data to a second virtual machine disk, the second virtual machine management program sends an IO data storage completion instruction to the first virtual machine management program; and in response to an IO data storage completion instruction received by the first virtual machine management program, storing the IO data storage completion instruction in a first virtual machine disk. By means of the method, fault tolerance and thermal migration of the virtual machine do not depend on traditional shared storage any more, a new synchronization method is constructed between two independent physical computers, and the method is easy to operate, stable and high in universality.
Description
technical field [0001] The present invention relates to the technical field of virtual machines, and in particular, to a method, apparatus, device and readable medium for synchronizing disks of virtual machines. Background technique [0002] With the wide application of virtualization technology, more and more enterprises choose to run key business on virtualized servers to improve the operation efficiency of key business. Virtualization applications based on standard x86 platforms are gradually popularized, and users have strong demands for virtualization high availability (HA) solutions. In the prior art, traditional shared storage solutions are usually used to implement virtual machine live migration and fault tolerance. For example, using storage Area Network (SAN), Network Attached Storage (NAS), Distributed File Storage System, etc. However, the synchronization method of shared storage has many problems, such as high cost, high technical difficulty, difficulty in main...
