I am trying some experiments involving the modification of the
permissions on pages but I can't seem to get a valid pte in the first
place. I wrote a little driver that has the following code in its init
routine.
void init(){
void * memory;
pgd_t * pgd;
pud_t * pud;
pmd_t * pmd;
version will work.
I'm not linux developer but I would guess that a patch or linux must be
made against the latest version. I don't see how a patch against 2.6.14
could be included in the main distribution (unless it applies cleanly to
the latest of course).

What version of gcc are you using? Also, is there a good reason you want
to use 2.6.14 instead of a newer kernel?

Looks like a simple matter of the rootfs file not being there. Did you
bunzip2 FedoraCora5-x86-root_fs.bz2?

Hi All.
I am new to UML, i download the linux-2.6.24-rc7.bz2 and

Then i follow the instructions:

Adding con0=... did not get rid of the parse_chan_pair errors.

I just tried UML with the new 2.6.25 kernel but it would not boot up
properly. I was using the same rootfs with 2.6.21.3 and it worked fine.
$ file rootfs/Gentoo-2006.1-AMD64-root_fs
rootfs/Gentoo-2006.1-AMD64-root_fs: Linux rev 1.0 ext3 filesystem data
(large files)
$ ./linux ubd0=rootfs/Gentoo
You can try this blog post I wrote about UML and networking. I wrote it
after the fact so it might be missing things but I did do things
manually all the way through.

Hi,
I am getting a new error message with UML. First a few lines of
Using a channel type which is configured out of UML
parse_chan_pair failed for device 15 : Configuration failed
and then the vfs can't mount the root partition specified with ubd0.
VFS: Cannot open root device "98:0" or unknow
I set up tuntap so that my uml instance has an ip, 192.168.0.1, and can
talk to the host, 192.168.0.254, which works fine but when I try to talk
to the rest of the world from uml any command will just hang.

Is there a way to view printk's from UML before the console is fully set
up? I am getting a segfault before printk can make its way to the
console so I can't view any output. Basically my session is this:

I'm trying to use UML so that I can hack on linux a bit but am having
trouble getting UML up and running. Initially I tried the kernel and fs
listed on the UML.sf.net site which worked ok except it didn't want to
load the hostfs module so I couldn't easily copy over any files on my
host system.
