Introduction
We customized KNOPPIX to include a virtual machine monitor Xen. We call it "Xenoppix".
Xenoppix sets up device drives using autoconfig function of KNOPPIX and enables to boot a guest OS on Xen.
News
- Release: Xenoppix (KNOPPIX5.1.1 + Xen3.0.4 + QEMU/KVM + HTTP-FUSE) which boot is accelerated by LCAT
- New Feature (chagelog)
- KNOPPIX is upgraded to 5.1.1(Japanese Edition) and Xen is upgraded to 3.0.4
- GRUB Menu includes two items; Xen3.04(kenrel 2.6.16.33) and normal KNOPPIX (kernel 2.6.19).
- Xen3.0.4 improved support for SMP and ACPI. The feature enables to merge
previous EFI version and normal BIOS version.
- "konppixHMV" command runs KNOPPIX on a full virtualization on IntelVT/AMD-V.
- "knoppixU" command runs KNOPPIX on a para virtualization.
- KVM(Kernel based Virtual Machine) is included. The version is Release 12 2007-01-23 on Linux 2.6.19.

KNOPPIX runs on "QEMU/KVM" |
- [Experimental] HTTP-FUSE (stackable/network virtual disk)
- It enables to boot Debian/GNU Linux Etch on Xen form Internet.
- HTTP-FUSE CLOOP is stackable/network virtual disk.. The virtual disk can be rollback to an old image.
- Reference
- Usage
- Xen3.04
- Boot with "Xen3.0.4" at GRUB Menu.
- Para virtualization
- Run # knoppixU
- KNOPPIX will boot via VNC.
- Full Virtualization
- If IntelVT/AMD-V is available, we can use full virtualization of Xen "HVM ".
- run # knoppixHVM
- KNOPPIX will boot via SDL(Simple DirectMedia Layer)
- KNOPPIXHVM command has options to boot from an iso file.
- # knoppixHVM [/path/to/isofile] [domain_name]
- Caution) Add "nofirewire" kernel option at GRUB Menu for Intel MAC.
- QEMU/KVM
- Boot "KNOPPIX(normal kernel)" at GRUB Menu on IntelVT/AMD-V.
- Include a KVM driver. The driver depends on IntelVT/AMD-V.
- # modprobe kvm-intel or # modprobe kvm-amd
- Run "kvm" command. The options are same for QEMU.
- # kvm -cdrom /dev/cdrom -boot d -m 256 -localtime
- A window will be appeared. The window bar indicates QEMU/KVM if the kvm
is effective. If not, the window bar indicates QEMU.
- Caution) If you boot with KNOPPIX(normal kernel) image(The second item of GRUB Menu),
add "nolapic noapic noapm" options for kernel at GRUB>
- [sample] OSZoo offrers many Disk images(OpenSolairs, Darwin, ReactOS, etc) for QEMU. Please try them on KVM.
- [Experimental] HTTP-FUSE
- Boot with "Xen3.0.4" at GRUB Menu on IntelVT/AMD-V.
- Confirm that "eth0" is IP reachable and Xen is running.
- # pump -i eth0
- # /etc/init.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".
(Click to enlarge the figure.)
- 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.
- Performance
- PI calculation(3 Million-digits) is used to compare.
- We confirmed the performance of kvm was very close to native CPU. However the IO was still slow.

- Minor Change: "Xenoppix(x86/x86_64) Hybrid DVD(Xen3.0.3+KNOPPIX-x86_64-5.0.1+Boot Acceleration LCAT) " with PV Driver for x86_64
- PV Driver for x86_64 is added. It makes fast the network of HVM (Full virtualization)
on x86_64. The previous version supports only PV for x86(32bit).
- PV Network Driver (for x86_64)
- At GRUB Boot, enter edit mode at "KNOPPIX/Xen3.0.3-0 (x86_64) (GRUB's
first item)". Add memory limitation option (Example: "dom0_mem=512M"
for 512MB Limitation.) at the first item for "Xen load" and boot.
- Example: kernel /x86_64/boot/xen-3.0.3-0.gz console=vga dom0_mem=512M
- On Domain0, please edit "/usr/sbin/knoppixHVM". Replace the "vif"
item from "type=ioemu " to "type=netfront".
- Run "knoppixHVM" . At GRUB boot, enter edit mode at "KNOPPIX
(normal kernel) (GRUB's 4th item)". Add "nosmp" option at the first item for "Linux kernel load" and boot.
- After boot KNOPPIX on HVM, Install PV modules as follows.
#cd /cdrom/sample/PV/x86_64/
#insmod ./xen-platform-pci.ko
#insmod ./xenbus.ko
#insmod ./xen-vnif.ko
- Edit "/etc/network/interface" on HVM to add "eth0"
statement (Red characters).
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
- After that run ifup eth0 ; pump -i eth0 . The PV Driver becomes effective.

- "Xenoppix(x86/x86_64) Hybrid DVD(Xen3.0.3+KNOPPIX-x86_64-5.0.1+Boot Acceleration LCAT) " is released
- Xen is upgraded to version "3.0.3". The DVD is Hybrid Bootable
DVD because it includes images for x86 and x86_64.It is good to check the performance of "Core2 Duo/Athlon64". Least Xen offers variable SMP CPUs and runs Linux kernels more than the
real CPUs. The DVD includes PV (Para-Virtualized) NIC Driver to make fast communication
on HVM (Full Virtualization).LCAT(Live CD Acceleration Tool kit) makes fast CD Boot on x86 and x86_64.
- New function of Xen3.0.3
- Solved UMA Video Card Problem
- Xen3.0.2 has a problem of memory conflict with UMA(Unified Memory Architecture) Video Card when HVM(Full Virtualization) is launched. 3.0.3 solved the problem and allows to use HVM on Note PC with Integrated
Graphic Chipset.
- Variable SMP CPUs
- Xne3.0.3 allows us to change the number of virtual CPU. Add "vcpus=8" option in hvm file. (Refer to How to use.)
- PV(Para-Virtualized) Network Driver
- The DVD includes PV(Para-Virtualized) Network Driver which makes fast communication on HVM. (Refer to How to use)
- Removed Memory limitation on Domain0 for HVM.
- The memory limitation of Domain0 is required to use HVM on Xen3.0.2. We
had to add "dom0_mem=***" option at GRUB Menu. Xen3.0.3 doesn't
require such option. Xenoppix reduces the boot menu on GRUB.
- Reduded Boot option on HVM.
- HVM of Xen3.0.2 requires to add some boot options to suppress BIOS function.
KNOPPIX on HVM need to add " -nolpic -nolapic -nosmp -noapm "
options. Xen3.0.3 doesn't require such options and makes easy boot OS on
HVM.
- New Problem(GRUB's EFI patch conflicts to AMD-CPU)
- GRUB which adds EFI(Intel Mac) patch doesn't boot on HVM of AMD-CPU. This problem wasn't caused on Xen.3.0.2. To solve the problem, Xenoppix offers 2 versions; Normal-GRUB and EFI-GRUB
.
- How to use
- Boot Xenoppix (Select X86 and X86_64)
- Xen3.0.3 allows to reduce boot menu on GRUB. Current menu has 4 items.
- KNOPPIX/Xen3.0.3-0
- Xen3.0.3+Linux 2.6.16.29-xen
- KNOPPIX (normal kernel)
- Normal x86 KNOPPIX kernel. Linux 2.6.17
- KNOPPIX/Xen3.0.3-0(X86_64)
- Xen3.0.3+Linux 2.6.16.29-xen for x86_64
- KNOPPIX (normal kernel, x86_64)
- x86_64 KNOPPIX kernel. Linux 2.6.17 for x86_64
- Run DomainU&HVM
- Xenoppix offers original commands knoppixU and knoppixHVM to run KNOPPIX on DomainU and HVM. Of course "xm" (Xen Manager)
is available.
- knoppixHVM boots KNOPPIX with the DVD image. It also allows to add option to designate iso file to boot other CD bootable OS.
- # knoppixHVM [/path/to/isofile] [domain name]
- knoppixU assumes that DHCP is available. Please add "nat" option when DHCP is not offered.
- Guest OS has limitation on X86-Domain0 and 86_64-Domain0. The following
table shows the available CPU environment.

- PV Network Driver (for x86 only)
- At GRUB Boot, enter edit mode at "KNOPPIX/Xen3.0.3-0(GRUB's first
item)". Add memory limitation option (Example: "dom0_mem=524288"
for 512MB Limitation. Unit is KB) at the first item for "Xen load"
and boot.
- Example: kernel /boot/xen-3.0.3-0.gz console=vga dom0_mem=524288
- On Domain0, please edit "/usr/sbin/knoppixHVM". Replace the "vif"
item from "type=ioemu " to "type=netfront".
- Run "knoppixHVM" . At GRUB boot, enter edit mode at "KNOPPIX
(normal kernel) (GRUB's second item)". Add "nosmp" option at the first item for "Linux kernel load" and boot.
- After boot KNOPPIX on HVM, Install PV modules as follows.
#cd /cdrom/sample/PV/x86/
#insmod ./xen-platform-pci.ko
#insmod ./xenbus.ko
#insmod ./xen-vnif.ko
- Edit "/etc/network/interface" on HVM to add "eth0"
statement (Red characters).
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
- After that run ifup eth0 . The PV Driver becomes effective.
- Boot with the sample ISO(Trusted HTTP-FUSE KNOPPIX) file.
- After boot with Xen Domain0, run the following command.
- # knoppixHVM /cdrom/sample/iso/httpfuse-trusted_20061101.iso httpfuse
- Caution: Trusted HTTP-FUSE KNOPPIX has a function of Trusted boot with TPM(Trusted
Platform Module) Chip. But current Xen didn't support vTPM and it boot
as a normal HTTP-FUSE KNOPPIX.
- Change the number of Virtual CPUs
- The easy way is to modify "/tmp/knoppix.hvm" file which is created by "knoppixHVM". Please add "cpus=8" option in the file and run the following command.
- # xm create /tmp/knoppix.hvm
(8 vCPUS on HVM. Click to Enlarge the figure.)

CD size" i
- "Xenoppix-x86_64(Xen3.0.2+KNOPPIX-x86_64-5.0.1) CD size" is released.
It exploits latest CPU (Intel Core2 Duo and AMD Athlon64).
- Xenoppix-x86_64 also works as KNOPPIX-x86_64.
- It includes GCC for X86_64. We could compile and run our applications. We compared Pi calculation between normal 32 bit KNOPPIX and KNOPPIX-x86_64. We confirmed approximately KNOPPIX-x86_64 makes twice faster than 32 bit KNOPPIX. (The following list shows the results.)
- Xenoppix-x86_64 boots both X86 and X86_64 linux kernel on HVM of Xen.
- We could run KNOPPIX-x86_64, Quantian(kerenl2.6), and ClusterKNOPPIX(kernel2.4+OpenMosix) on HVM of Xenoppix-x86_64.The following figure shows the result.
- Xenoppix-x86_64 looks like KNOPPIX but all packages are replaced for X86_64.
- Boot loader is GRUB which supports EFI. It enables boot on Intel MAC.
- Linux kernel is 2.6.16 for Domain0 of Xen and 2.6.17 for KNOPIX-x86_64.

- Xen is updated to version 3.0. Host-Xenoppix(Knoppix on Domain0) boots Guest-Xenoppix(Knoppix on DomainU)
with same kernel and same Root fileSystem.
- Network is selectable; "Bridge" or "NAT". "Bridge"
mode requires external DHCP. "NAT" mode is independent of external
network, so we can boot DomainU without network connection.
- Usage
- Boot with "KNOPPIX/Xen3.0".
- GuestOS(DomainU) is booted from command line. The command name is "knoppixU".
When "nat" option is added, the network is NAT mode. If there is no option, the network is "Bridge mode" and requires
external DHCP service.
- Example: $ sudo knoppixU nat
- CAUTION: The console shows boot sequence of GuestOS(DomainU). It includes many many
Error messages (Examples: Couldnt get a file descriptor, mmap /dev/map:
Resource temporally unavailable). Don't care please. The boot of GuestOS
takes about 5 minutes. :-)
- Xenoppix on DomainU boots with Full screen of "800x600". The Xenoppix on DomainU accepts "shutdown" command . After shutdown, it returns to Xenoppix on Domain0.
- Technical Detail
- Same Kernel(Linux2.6.12.6+Xen3.0) on Domain0 and DomainU.
- Same Root FileSystem(cloop file of CD-ROM) on Domain0 and DomainU.
- DomainU maps CD-ROM directly.
- Description of domain setting file. disk = ['phy:/dev/cdrom,hdc,r']
- Device Mapper is not used.
- The update of GuestOS is covered by"UNIONFS" of original KNOPPIX. Thanks Klaus. :-)
