Flavio,
Try the patch from here:
http://www.coherenthosting.com/prj/uml/skas-2.6.23.patch.bz2
I haven't tried it yet as I've been waiting for something else, but it
seemed to copy correctly from Jeff's original email. Please let me know
how it works (or not).

Fabio,
Let me know if you want a newer, pre-compiled guest kernel (I have one
for 2.6.20.6). While this will not help with the TLS issue, it does
offer a LOT of bug fixes. In the mean time, you can find compilation
instructions on the main website at:
http://user-mode-linux.sourceforge.net/compil
I normally create the guest instances on an EVMS object. I then take a
snapshot of the device after I've "frozen" and "flushed" the UML. Once I
have the snapshot created, I then reactivate the guest (let it continue
running) and deal with mounting and backing up the instance from the
snapshot.

Derek,
If I was to guess, I would suggest verifying that your image is complete
and contains an init executable.
Where did you download the base image from? Can you mount via loopback
and verify that it is correct and readable? Finally, do you have the
correct file system support (ext3, jfs, etc.

Flavio,
First, please stop posting in HTML. It is challenging for some software
to deal with in a safe a proper manner.
Second, do you have write permissions on the device in question? In
other words, assuming that you're running the UML instance as user
'myuml', do you see something similar to t

Do you have write permissions to the current working
directory? I don't know what err=113 means, but the guest instance needs
permissions to create the file on the local file system.

Are you setup to forward IP packets on the host? Something like:
~$ cat /proc/sys/net/ipv4/conf/all/forwarding
1
~$
This assumes that you're using your host as a gateway. Alternatively, is
br0 connected to a physical device? For example:
~# brctl show
bridge name bridge id STP
Naveen,
You will need to make modifications to the rootfs to
get it to work, starting with the devfs references. Devfs is no longer
supported. You can find a lot of references and documentation at the

I haven't done this with the actual root filesystem. I have done this
with "data" filesystems. However, I would suspect something like the

Does sysemu now work? I haven't looked at this patch in several months,

You can verify the use of tmpfs with the
