Hello friends!

In this week, i had a problem with Xen version 3.0.2_09749-0.7 on SLES10 for x86, when
the initrd-xen file was loaded. On console, various messages about "No space left on device"
appears later that the "/dev" was monted on a tmpfs filesystem (for udev).

The only sollution for this problem at that moment, was remove the "dom0_mem=192M" and the
"mem=1024M of my GRUB configuration file (menu.lst on SuSE).

My dom0 configurations are:

- Intel(R) Xeon(TM) CPU 2.80GHz
- 1 GiB RAM

title XEN
    root (hd0,0)
    kernel /xen.gz dom0_mem=192M
    module /vmlinuz-xen root=/dev/system/root vga=0x314  resume=/dev/system/swap  splash=silent showopts acpi=off apm=off mem=1024M
    module /initrd-xen

df command output:
 # df
Filesystem           1K-blocks      Used Available Use% Mounted on
                       2097084   1717340    379744  82% /

/dev/sda1               256666     23426    219988  10% /boot
                       2097084    174604   1922480   9% /var

# xm dmesg:
(attached file) :-)

# rpm -q udev:

# uname -a:
Linux omega #1 SMP

The problem was resolved, but I need to understand if this is a "bug" on Xen / udev, or
I made a mistake configuration.

Looking for bug reports, I don't found none report bug related with this...

Thanks!!!! :-)
