Dear, We released VMKNOPPIX. It was called Xenoppix but renamed to VMKNOPPIX because it became a collection of Virtual Machine Softwares. http://unit.aist.go.jp/itri/knoppix/index-en.html VMKNOPPIX includes Xen3.0.4(DomainU & HVM Domain), KVM14, VirtualBox, GPLed KQEMU, and normal QEMU. There are many techniques of Virtual Machine, para-virtualization, full-virtualization with virtualization instruction(IntelVT or AMD-V), dynamic translation etc. The VM softwares runs with OS images offered by some sites(For instance OSZoo's QEMU images).Have fun with the techniques! OSZoo's QEMU images http://www.oszoo.org/wiki/index.php/Category:Operating_System_Images VMKNOPPIX includes "OS Circular" environment. OS Circular enables to boot OSes on Xen with a globalized virtual disk "HTTP-FUSE CLOOP". VMKNOPPIX includes benchmark sotwares. We compared the results. (See below) Pi calculation for CPU benchmark http://h2np.net/pi/pi_quick_start.tar.gz dbench for IO benchmark tbench for Network benchmark Xengine for Graphic Benchmark VMKNOPPIX includes xenoprifle to take profile of HVM Domain OS. VMKNOPPIX is optimized by LCAT for fast CD boot. http://www.alpha.co.jp/biz/rdg/ac-knoppix/index_en.html ============================================================================* *** Virtual Machine Uages ------------------------------------------------------------ * Xen Boot with the first option "KNOPPIX/Xen3.0.4-0" of GRUB. To run DomainU with KNOPPPIX. # knoppixU To run HVM Domain with KNOPPPIX on IntelVT or AMD-V. # knoppixHVM Caution) Add "nofirewire" kernel option at GRUB Menu for Intel MAC. ------------------------------------------------------------ * OS Circular Boot with the first option "KNOPPIX/Xen3.0.4-0" of GRUB on IntelVT or AMD-V. # pump -i eth0 # /etc/inint.d/xend start # httpfuse-hvm.sh Selection Menu will be appeared. Select a near site. Contents Menu will be appeared. Select your favorite image. The OS will be appeared. Current Debian Etch has accounts, "root/http-fuse" or "http-fuse/http-fuse". Caution) Add "nofirewire" kernel option at GRUB Menu for Intel MAC. Caution) The console must be wider than 80x24to run httpfuse-hvm.sh, because "dialog" requires wide console. If the console is small, the message "httpstoraged is ready ..." will continue. The technical detail was presented Virtualization Miniconf at LinuxConfAu07. http://virtminiconf.linux.hp.com/program/os-circulation-environment-201ctrusted-http-fuse-xenoppix201d Slide PDF http://unit.aist.go.jp/itri/knoppix/20070118-LCA-HTTP-FUSE.pdf ------------------------------------------------------------ * VirtualBox Boot with the second option "KNOPPIX(normal kernel)" on GRUB. # modprobe vboxdrv # VBoxSVC & # VirtualBox After that, setup VM environment interactively. The CD-Drive is setup at the main menu after Interactive setup. ------------------------------------------------------------ * kqemu/KVM/QEMU Boot with the second option "KNOPPIX(normal kernel)" on GRUB. Script "qemu-knoppix.sh" prepares network environment, shared memory for KQEMU, and drivers for KVM or KQEMU. The priority is as follows. 1) If kvm drivers effective, kvm runs. 2) If kqemu is effective, kqemu runs. 3) If kvm and kqemu aren't available, qemu runs. "qemu-knoppix.sh" aslo accepts the follwing options. -no-kvm : disable KVM kernel module usage -no-kqemu : disable KQEMU kernel module usage -no-module: disable all kernel module usage For examples, the following command runs kqemu. # qemu-knoppix.sh -no-kvm ============================================================================ *** Benchmarks * pi calculation # time /opt/pi_quick_start/pi 3000000 * dbench (Read /usr/share/dbench.client.txt) # dbench 1 * tbench (Read /usr/share/dbench.client.txt via network) On Host # tbench_srv On Guest # tbench -t 60 1 "HostIP.
