高速化・多種サポートを実現できる直接 I/O と呼ばれる技術が着目されてきている．本論文では，直接I/Oを実現し，I/O をハードウェアレベルで仮想化する技術として PCI Express (PCIe) をベースとした I/O 仮想化技術を取り上げ，仮想化環境で必要とされる仮想マシン移動をサポートするための技術について議論する．我々は仮想マシン移動をサポートするための技術としていくつかの可能性を検討している．それらは I/O MMU を拡張する方式，PCIe スイッチ内に書き込み記録テーブルを保持する方式，PCIe スイッチで書き込みをマルチキャストする方式である．今回我々は，PCIe スイッチ内に書き込み記録テーブルを保持する方式を実装し，効果の見積もりを行った．その結果，直接 I/O を用いた仮想マシンでも，見た目の停止時間がわずかに増加 （＋5ms）

popular and importance of virtual machine (VM) system increases. Current VM system has problems in the performance of I/O. So the “Direct I/O” mechanism will become key technology of future virtual machine systems to improve I/O performance of virtual machines. In this paper, we propose some methods of live migration for VMs with Direct I/O. In Direct I/O environment, there are some difficulties to move VMs. To solve such difficulties, we use PCI Express (PCIe) switch and hardware mechanism in PCIe switch. We propose three mechanisms for migrate VMs: extension of I/O MMU, page listing in PCIe switch, and multicasting in PCIe switch. We implemented the second method for testing and estimated additional stop-period of migrated VM at 5ms.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-07-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"19","bibliographicVolumeNumber":"2010-ARC-190"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:29:21.642040+00:00","updated":"2025-01-21T23:39:02.920205+00:00","id":70042}
