More Information
Summary:The invention discloses a virtual machine resource pool starting optimization method and system and a medium. The method comprises the steps that after a virtual machine resource pool starting command is received, a related virtual machine set Svm is recognized; determining a common mirror image set used by the virtual machine set Svm; determining a to-be-prefetched public mirror image set required to be prefetched based on the public mirror image set and a system free memory; and executing prefetching operation of the to-be-prefetched public mirror images according to the to-be-prefetched public mirror image set so as to improve the starting speed of the virtual machine resource pool. The virtual machine resource pool starting optimization method is a data pre-fetching technology based on data sharing degree weighting and oriented to a memory-limited physical server, data of a virtual hard disk can be pre-fetched for a plurality of virtual machines running on the same physical server, and the starting and ru
