In debian stable, kvm-nbd command is from pacakge kvm, please see=20
http://packages.debian.org/lenny/amd64/kvm/filelist

If you are using Debian SID, you should use qemu-kvm instead of kvm.=20

nbd-client command is from package nbd-client, please see:
http://packages.debian.org/lenny/amd64/nbd-client/filelist, It is in /s=
bin=20
directory, so you should use root to run it.

qemu-nbd is from package qemu-utils, I have not use it, but I think it =
should=20
do the same thing as kvm-nbd.=20

I don't know fedora exactly, but I think fedora should have relevant pa=
ckage.

Best Wishes.=20
