Abstract
Disclosed are operating methods of a server and a node, and apparatuses thereof, and more particularly, to operating methods of a virtual machine server and a virtual machine node, and apparatuses thereof. The operating method of the virtual machine server according to the exemplary embodiment of the present invention includes: generating index information of blocks for booting a virtual machine in a virtual machine image; generating list information of neighboring nodes for a target node; and transferring the index information and the list information to the target node.
Claims15
An operating method, comprising:
- generating index information of blocks for booting a virtual machine, the index information indicating a reading pattern of a virtual machine image during a booting sequence;
- generating list information of neighboring nodes for a target node;
- and
- transferring, from a virtual machine server to the target node, the index information and the list information,
- wherein the index information comprises reordering blocks in the virtual machine image, such that two blocks separated prior to the reordering are disposed directly adjacent to one another after the reordering,
- wherein the virtual machine is booted using received blocks while sequentially receiving more blocks from the neighboring nodes, and
- wherein the list information is generated based on a round trip time (RTT) for nodes configured to access the virtual machine server.
