The greatest issue of wide area live migration is the bandwidth bottleneck of wide area network (WAN). The memory of a virtual machine (VM) must be transferred via slow network while the disk image can be synchronized background as it is not updated frequently. We focus on a case that page cache occupies the large portion of the VM's memory usage. We proposes a fast wide area live migration mechanism, where the page cache is restored from the disk image at the destination and is not transferred via narrow network. Preliminary evaluations showed that our prototype reduced total migration time of live migration in a narrow bandwidth network. Future work includes considering the network delay and further analysis of the evaluation results.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告組込みシステム（EMB）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-11-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"2012-EMB-27"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
