BitVisor: a thin hypervisor for enforcing i/o device security
Takahiro Shinagawa,Hideki Eiraku,Kouichi Tanimoto,Kazumasa Omote,Shoichi Hasegawa,Takashi Horie,Manabu Hirano,Kenichi Kourai,Yoshihiro Oyama,Eiji Kawai,Kenji Kono,Shigeru Chiba,Yasushi Shinjo,Kazuhiko Kato +13 more
TL;DR: A hypervisor architecture, called parapass-through, designed to minimize the code size of hypervisors by allowing most of the I/O access from the guest operating system (OS) to pass-through the hypervisor, while the minimum access necessary to implement security functionalities is completely mediated by thehypervisor.

HyperSpector: virtual distributed monitoring environments for secure intrusion detection
Kenichi Kourai,Shigeru Chiba +1 more
TL;DR: A virtual distributed monitoring environment called HyperSpector is described that achieves secure intrusion detection in distributed computer systems by using virtualization to isolate each IDS from the servers it monitors.
Proceedings ArticleDOI
A Fast Rejuvenation Technique for Server Consolidation with Virtual Machines
Kenichi Kourai,Shigeru Chiba +1 more
TL;DR: A new technique for fast rejuvenation of VMMs called the warm-VM reboot is proposed, which enables efficiently rebooting only a VMM by suspending and resuming VMs without accessing the memory images and reduces the downtime and prevents the performance degradation due to cache misses after the reboot.
Journal ArticleDOI
Fast Software Rejuvenation of Virtual Machine Monitors
Kenichi Kourai,Shigeru Chiba +1 more
TL;DR: The warm-VM reboot enables efficiently rebooting only a VMM by suspending and resuming VMs without saving the memory images to persistent storage and achieved higher total throughput than the system using VM migration and a normal reboot.
Proceedings ArticleDOI
A dynamic aspect-oriented system for OS kernels
TL;DR: This work proposes a dynamic aspect-oriented system for operating system (OS) kernels written in the C language that allows the users to pointcut not only function calls but also member accesses to structures and achieves sufficient execution performance for practical use.
