Method and apparatus for Virtual machine disk failure recovery

The present invention includes the steps of calculating the total resource that is in the entire virtual network I / O, and disk I / O performance of the system, how to repair the failed disks of the virtual machines in the virtual machine; Calculating a resource of the operator operating the source for said virtualization system; Calculating the amount of user source of the network I / O, and disk I / O; Calculating the total resources, and a source operator recovery resource network I / O, and disk I / O bandwidth to spare, while based on the user's original guarantee the performance of the other virtual machines to assign to the failure recovery; And a step of performing the disk failure recovery by recovering the failing disk copy is a replica of the disk by a stream (Stream) method using the repair mendeo planetary disk stored the resource based on the system.
