Japanese KNOPPIX is a laucher of "virtual appliance" for Debian and Ubuntu

[Kuniyasu Suzaki <k.suzaki@aist.go.jp>]

Dear,

Japanese KNOPPIX6.2DVD includes "OS Circular" which is a kind of "virtual appliance".
    http://www.rcis.aist.go.jp/project/knoppix/knoppix62DVD-en.html

OS Circular offers disk images of Debian and Ubuntu with LBCAS (LoopBack Content
Addressable Storage). It enables us to boot Debian or Ubuntu on KVM or KQEMU without installation.
The disk images of Debian and Ubuntu are updated weekly and allow to roll-back to previous images.
Please try. :-)
