D-Visor + D-System Monitor
D-Visor and D-System Monitor, developed by the DEOS project, are released in this page.
D-Visor provides D-System Monitor with functions to monitor I/O requests and memory contents, in addition to ordinary functions of a virtual machine monitor. The following two types of D-Visor were implemented.
- D-Visor86: D-Visor for x86 multi core CPU
- QEMU-KVM: D-System Monitor incorporated in the QEMU-KVM
D-System Monitor watches guest OSs from outside and detects abnormal behavior. It uses functions provided by D-Visor to monitor I/O requests and memory contents. The following three monitoring mechanisms were implemented.
- FoxyKBD: mechanism to detect key loggers
- RootkitLibra: mechanism to detect rootkits which tamper with file meta data
- Waseda LMS: mechanism to detect inconsistency of kernel data
D-Visor86 + D-System Monitor
D-Visor86 runs directly on hardware. D-System Monitor runs on an OS on one VM and monitors the user OS (target OS) on another VM.
- Hardware: BX-100n-DC5000-C0 made by CONTEC Co., Ltd.
- Software: Ubuntu 10.04
- Document D-Visor86 + D-System Monitor Setup Manual 2.0 (in Japanese)
- Software dvisor86-dsysmon-0.1.0.tar.gz (25.5MB)
QEMU-KVM + D-System Monitor
QEMU-KVM runs on a host OS and D-System Monitor incorporated in the QEMU-KVM monitors a guest OS (target OS) on the VM.
- Hardware: PC with x86_64 CPU that supports Intel VT (As of now, AMD-V cannot be used.)
- Software: Ubuntu 12.04 LTS x86_64
- Document QEMU-KVM + D-System Monitor Setup Manual E1.0
- Software qemu-kvm-dsysmon-0.1.0.tar.gz (139KB)

D-Visor86 was researched by University of Tsukuba participating in the JST CREST "Dependable Embedded Operating System Aiming at Practical Applications" (DEOS) project.
D-System Monitor was researched by University of Tsukuba, Waseda University, and Keio University participating in the JST CREST "Dependable Embedded Operating System Aiming at Practical Applications" (DEOS) project.
