Hi.
I've read that Lustre Developers (http://wiki.lustre.org) use UML to debug.
I would like to use UML to test Lustre. I noticed that they provide patches
for Linux 2.6.18 (vanilla), but it seems this version does not build for UML.
So, my question is:

Hi.
Is there a way to make UML use more than one processor?
Under full load, it uses one of the 2 available processors of
the host machine.

Write a module that can manage an interrupt.
And I'd like to use UML for it.
I'd like to simulate a hardware device, that might be
outside of UML of perhaps compiled in in the kernel.

Hi,
I'm writting a device driver. I'd like to use UML with a
"fake" hardware device that generates IRQs.
In the driver, I need to catch the IRQ, read to the
device and write to the device.
How can I get started?

Hi.
I'm running Debian, host 2.6.16-1-686-smp.
I noticed a similar bug:

UML Fails when host kernel is linux-image-2.6.16-1-k7
What is the best solution?

Questions:

Well, the UML can connect to any port in the host
And also to anywhere in the Internet pretending to be
your host.
I think most programs in your host won't be able to
tell if a connection comes from the host of from the UML

This won't work. This is ICMP
You can browse a web page, telnet to a given port, etc.

It would be nice to debug the sshd issue, and I hope you

I was sleepy :) I'm sending it again.
I added some text from an email Henrik Nordstrom sent.
I checked out the XML sources from SF.net but faq.xml
doesn't seem to be the source of faq.html.

I just noticed you can use count=0 to avoid the extra byte.
So, this seems to be the easiest way to truncate a file in Linux.
