If you get an error such as that, it means you need to include it as
either a module, or compile it into the kernel. It's not a problem
with the doc, just a misconfiguration at config time.

This should help out quite a bit, I just dug it up:
http://www.howtoforge.com/kernel_compilation_centos
It shows you how to create a kernel for centos, starting with vanilla
(official kernel.org) sources. You can patch that tree before
compiling.

He's looking for a more "official" way to compile it, like, against
RHEL5/CentOS5 sources and probably even put it into an RPM so the
system will handle it correctly.
I don't know how to do this myself since with CentOS/RHEL I've always
just let the system handle the kernel. (one of the reasons I
Hi,
I'm centralizing my image(s) to an NFS share currently to save space
on my 3 UML hosts.
This is the first time I've used NFS as a partition to store backing files.
The issue I'm running into is I can start one UML instance, but the
second UML instance can't get a lock on the backing file. (I'm

Hi,
Another thing I'm falling short of answers for. I know there used to be
a file size limit of 2G for linux back in the 2.2 days ( think it was
2.2 ), but I seem to be stumbling across it on 2.6. I'm running a host
of 2.6.11 with skas3v8, and when I try to start up a UML instance (guest

No process inside UML would continue to run, not even bash, yes; if you talk
about the xterm you see, that is a process running on the host, so it should
keep running (and updating the displayed images).
Great, that did the trick! Thanks alot, much appreciated.

Hi Dan,
Thanks for your reply. It's now working! I had to change it a bit like this:

I am not sure what I did wrong in my setup but I get the feel
