  1. 仮想実行環境を管理するためのライブラリ 大山 恵弘 米澤 明憲 （東京大学／ＪＳＴ） 情報処理学会第９９回ＯＳ研究会

  2. Virtual Execution Environments (VEE) • Systems • CPU emulators: QEMU, bochs, Quasar • VMM: VMware, Xen, Denali, LilyVM, UML, SBUML, Virtual Multiprocessors • Virtual resource view: Chroot, jail, Zap, SoftwarePot, World OS 情報処理学会第９９回ＯＳ研究会

  3. A Big Picture • Study on next-genration software that aggressively uses VEEs • Sustainable Computing • Virtual Internet, virtual Grid • Computation migration • Intrusion/failure/bug analysis via playback • Sandbox, IDS, honeypot 情報処理学会第９９回ＯＳ研究会

  4. Quasar Quasar Denali Virtual Internet on Heterogeneous Machines Win MacOS Linux Linux Linux SBUML SBUML Linux NetBSD FreeBSD Linux (SMP) LilyVM LilyVM LilyVM VirtualMP VirtualMP NetBSD Win MacOS NetBSD Linux 情報処理学会第９９回ＯＳ研究会

  5. Difficulty in Developing Virtual Internet • Deployment • A great amount of effort:login, copy virtual disks, start VMs, checking fault, recover, … • boring • error-prone 情報処理学会第９９回ＯＳ研究会

  6. Our Approach • Toolkit for VEE-based software • VEEML: VEE Management Library • fork/exec/wait/kill-flavored APIs • veemd: VEE Management Daemon • VOP: VEE-oriented programming paradigm 情報処理学会第９９回ＯＳ研究会

  7. What VEEML Makes Easier • Creating/controlling/synchronizing hundreds of VEEs • Deploying VEEs on remote machines • Combining various VEE systems 情報処理学会第９９回ＯＳ研究会

  8. Our Scenario (1) veemd veemd veemd veemd veemd veemd veemd veemd veemd veemd veemd veemd veemd veemd veemd 情報処理学会第９９回ＯＳ研究会

  9. Our Scenario (2) • Programming using VEEML develop libraries and daemons develop VEE-using apps in Ruby … VEEML- Ruby VEEML- Python VEEML- Java VEEML-C veemd end user 情報処理学会第９９回ＯＳ研究会 our team

  10. VEEML API • vee_exec(vee_type, snapshot_file, …) • vee_snapshot(vid, snapshot_file, …) • vee_suspend(vid), vee_resume(vid) • vee_wait(vid, status) • vee_kill(vid, sig) • vee_makediff(difffile, snap1, snap2) • vee_mergediff(vid, difffile) • vee_getprio(vid), vee_setprio(vid, prio) 情報処理学会第９９回ＯＳ研究会

  11. VID: VEE ID • Globally unique ID for specifying VEE • Independent of VEE’s physical location • Given when VEE is created • Used for controlling VEEs 情報処理学会第９９回ＯＳ研究会
