However, conventional operating system debugging environments have not been able to satisfy the following demands at the same time: 1) assuring the stability of the debugging environments 2) an easy customization of the debugging environment for new operating systems and new I/O devices, 3) efficient execution (especially I/O execution) of the operating system under the debugging environment. In this paper, we propose a novel operating system debugging method using the lightweight virtual machine monitor. This method can be applied to any operating systems on PC/AT compatible hardware, bacause the virtual machine monitor provides real hardware interfaces. The monitor also provides lightweight memory region protection mechanism, which enables the remote debugging function in the monitor to work stably even when the operating system under this debugging environ ent works inproperly owing to its bugs. Besides, the monitor provides partial emulation mechanism. Owing to this mechanism, the operating system on the monitor can achieve efficient I/O execution on various I/O devices. We evaluated this debugging method quantitavively, and confirmed that this method can provide about 5.4 times as high I/O performance as the existing hosted virtual machine monitor.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1751","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1735","bibliographicIssueDates":{"bibliographicIssueDate":"2005-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"46"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"システムソフトウェア設計・構成論"}]},"weko_creator_id":"11"},"id":10593,"updated":"2025-01-20T06:29:20.004833+00:00","links":{}}
