BlackBerry® DevCon Americas,
Still having problems with everything fedora right now.
I have now noticed that Fedora 15 will not run User Mode Linux..
Running a uml kernel with sensible parameters (or even no parameters)
results in:
Locating the bottom of the address space ... 0x1
Locating the top of the address space
ill let you know how I get on.

Interestingly with security= set to something other than selinux I
dont see the crash. I am assuming most people run with selinux
disabled.

Hi All.
I have been using user mode linux since 2004, but I have decided to
update my images to fedora 15.
However I cannot get a stable uml kernel to run this image.
For instance 2.6.39.1 crashes when I try "yum update". The errors on
the console are shown at the end of this email.
I get the same
I notice that a few people on the web, plus myself, have found it
impossible to compile user mode linux with fedora 11.
It gets pretty near the end, before dying with:

LD init/built-in.o

/usr/bin/ld:arch/um/kernel/vmlinux.lds:1: ignoring inva
Did you disable things in cron?
updatedb for instance could do this.
Have a look through the crontab and related directories and you may
spot something.
Just a thought...

I would still get you to update the host kernels to something newer.
That way you are sure it is not a kernel version think. 64 bit support
is much better as the guest kernels get newer.

Hi.
Having made the swap from 32 to 64 bit hosts myself this month, I have
found them to be very reliable and without the problems you seem to be
happening.
You are using a really old kernel. I suggest upgrading both the host
and guest kernels to something more modern. Previously I had been
using

Thanks for the link. I will give that telnet server a go and see if it
is any different.
Just to let you know, I do currently allow users to access their
guests via a tap device, and in general it works really well. However,
some of my practical exercises get the users to configure their own
firew
I am wondering if anyone could offer me some advice on telnet access
to the UML console.
I run linuxzoo.net, which has very poor console access for users right
now (it relies on network logins direct to the guests).
Im trying to fix that...
I am using something like "con1=port:5800". I have in.tel
After playing with con:port, and its use in a chroot, I wonder if
those with versions of UML documentation which refer to con:port would
find the following two pieces of information useful:

Some sites suggest that :port will work
I was about to update my host kernels from the somewhat dated versions
I am using.
However, blaisorblade's host patches only seem to go to
2.6.20-v9-pre9. From what I can tell, the current stable kernel is
2.6.23.
I did try to patch from the 2.6.20 version I found, but a few of the
hunks failed.
Create a tap device for your uml machine as normal.
In vmware, configure a vmnet device to use the tap device.
Personally I have been working with virtualbox instead of vmware for
my non-linux emulations, as this allows the tap device to be used
directly instead of having the vmnet layer of vmware
Wierdly I was just looking at the package for the vlan support.
There is no documentation on this, but scanning the source code you
use the telnet interface to the switch and from there the process is
menu driven. Looks like you can have both tagged and untagged.
However, there is a comment in the
I have looked at it myself, but not tried it. In the readme it does
talk about UML, for instance:
"with UML you can: (1) use "-unix /tmp/uml.ctl" for vde-switch (2) use
"eth0=daemon,,/tmp/vde.ctl" for UML"
Thus it seems to use the daemon interface of ethx= on the kernel command line.

You can see that your default policy is ACCEPT, so your rule:
> iptables -A FORWARD -p icmp -m limit --limit 1/m -j ACCEPT
will accept the packets in the limit, and if it is out of the limit
the packet is accepted
by the default policy.
> Chain FORWARD (policy ACCEPT)
Instead you can do:
iptab
been so long since I updated my uml kernels (my current kernel
is 2.6.7), I am wondering now which patches I should be applying?
Any thoughts?

I have exactly the same problem compiling on a 32 bit machine.
Looking at the ignored errors, they seem to be about things which have
already gotten into
the kernel. However, the tls.c patch seems to be incompatable and
different in a way that I was too scared to adapt.

Any chance you still have cron running? It might kick in after an hour or so.

Is anyone still involved with sbuml?
SBUML is one technique for saving and restoring running UML processes.
I would love to get this working with the current 2.6 SKAS kernels.

Well I definitely wont do that!

Nope. 64 MB per host. I have not had more than 10 per machine so far,

We have a cluster of 5 machines, each running about 15 UMLs. Things

die for a while.
