in short:
it`s quite some work to be done to have your uml 2.6.21 with root-fs up and
running and working cleanly. whenever i search the net for some appropriate
UML fs image, those i find are very often old and outdated...
Hmm... I'd think we need a wizard for configuration. Plus some distro-like
work for some specific issues - if I want to deploy a VM with hostname x,
network config y, and with Xnest running, I need an easier way to do that.
I think this can be solved by having the network auto-configure itself
and make the startup scripts responsible for bringing up the interface
and starting dhcp server on that interface. This is simple and does not
require changes to the images. (it takes care of dns, ntp, smb, etc..)
You can add settings on kernel command line and parse them inside UML - we
need standard packaged utilities for that (one of the rootfs builder
installed such stuff).
That would certainly complicate things quite a bit.
is there a project/website which is offering such ready to run "UML
kernel+rootfs release bundles" for download (i.e. new kernel,generic
root-fs, modules inside, sources inside, compiler inside - in sync with the
latest stable vanilla) , or , would it make sense to establish such project
? i.e. besides releasing the kernel, also releasing sort of a kernel
"runtime kit" and/or "devkit" ?
The runtime kit is there on nagafix.co.uk. The devkit is a main idea - most of
the work is to put something on the UML wiki and market well the idea -
creating such an image would be easy. But I haven't clear what you're talking
about - kernel development (why sources inside) or userspace development?
Also integrating all possible debug stuff would be useful, but I don't know
what's needed.
i think this could be very helpful for linux-kernel, because it could be
tested by more people more quickly, more easily and thus, more often. just
download, do few steps for setup, start up that virtual machine and there
you go testing, hacking into the sources, do all that things you never
would do on your main system, whatever....
it would probably also add benefit to UML itself.
We need three things:
a) more performance
b) more users
c) more developers
a) leads to c), and b) too.
does this sound dumb? i don`t know, so please comment.
No, it's not dumb. I'm even wanting to have a "Vmware-like" interface. Or at
least standard scripts for guest management.
I reckon that one critical thing which could drastically increase the
user base would be to have a working virtual framebuffer implementation.

PS:
ok, this would be some 500M to 1G download, but there`s lot`s of bandwidth
today - and P2P/Bittorrent.....
uml.nagafix.co.uk has some good kernels + images. With compression, they're
even as little as 50 Mb.
However, making UML easier to use, and marketing it for more application, is
very important. Various project do exist but they're not integrated, and they
do not try to (netkit is for network experimentation, but is also better as
VM management tool).
In short, we'd need somebody helping out really with the website (there is the
wiki but you must request an account via email, and it's not the main
website), with uml-utilities, and with new uml-utilities (you know
dm-snapshot is a faster COW? Something to setup it automatically would be
good).
There would be more to say on this, but I can't right now (I've other stuff to
do).
