Virtual resource re-balancing method based on consistency algorithm

Abstract

The invention discloses a virtual resource re-balancing method based on the consistency algorithm. The problems that in the prior art, when main host machines and standby host machines break down, virtual machines on the standby host machines cannot work, and a system is influenced are solved. The virtual resource re-balancing method includes the following steps: (1) an own hash block is distributed to each host machine, and each host machine becomes a manager of the corresponding hash block; (2) the virtual machines are created, each virtual machine has a unique identification, hashing is carried out on the unique identifications through the system, a key is obtained, and a hash list is generated; (3) the host machines obtain unique node markers D, and the key and the D have the unique incidence relation; (4) a DHT ring is generated with the DHT algorithm according to the unique identifications of the host machines; (5) the virtual machines are mapped to the host machines according to the unique incidence relation between the key and the D, and the virtual machines are managed by the host machines. The virtual resource re-balancing method is less in resource consumption, stable in system and high in capacity of backup for disaster recovery.

Description

technical field [0001] The invention relates to a cloud host disk cloning method, in particular to a virtual resource rebalancing method based on a consistency algorithm. Background technique [0002] Cloud host is a host product in the cloud computing service system. This product effectively solves the defects of difficult management and weak business scalability in traditional physical lease and VPS services. The price of cloud hosting service is lower than that of traditional physical hosting, and there is no need to pay a deposit. It is very flexible, and when the user's business scale expands, cloud hosting can quickly realize business expansion. Cloud computing can save users from owning and maintaining complex computing infrastructure, so it is welcomed by more and more users. In order to ensure the reliability of users' business, cloud hosts need to provide failover and disaster recovery. [0003] The main purpose of building a disaster recovery system is to preven...

Problems solved by technology

[0004] In the prior art, a virtual machine is created on a host machine, and each host machine has a backup host machine, and the data of the virtual machine on the main host machine is synchronized to the backup host machine in real time. When the main host machine fails, enable Backup host, if both the master host and the backup host fail, the virtual machines on the backup host will not be able to work, and the system will be affected
