Xen users - Dec 2005 - Problem while booting dom0 in FC4 for Xen-2.0

hi ,
          Booting process hangs after giving following warning ,
"Current emulating unsupported memory access in /lib/tls libraries. The
emulation is very slow . To ensure full performance you should execute
mv /lib/tls /lib/tils.disabled"

This warning comes even after performing ''mv ''. 

Following is grub config:
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,1)
#          kernel /vmlinuz-version ro root=/dev/sda3
#          initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=20
splashimage=(hd0,1)/grub/splash.xpm.gz
#hiddenmenu
title Fedora Core (2.6.11-1.1369_FC4smp)
        root (hd0,1)
        kernel /vmlinuz-2.6.11-1.1369_FC4smp ro root=LABEL=/ rhgb quiet
        initrd /initrd-2.6.11-1.1369_FC4smp.img
title Xen 2.0 / XenLinux 2.6
       root(hd0,1)
       kernel /xen-2.0.7.gz   dom0_mem=720000
       module /vmlinuz-2.6.11.12-xen0   root=/dev/sda3 ro console=tty0

Following is the output of fdisk -l
Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        5099    40957686    7  HPFS/NTFS

/dev/sda5            9475        9729     2048256   82  Linux swap / Solaris

Xen-3.0 gives problem of Insufficient memory for dom0.

I have been successfully running Xen-2.0 with RHEL-3 kernel-2.4.20 with dom0 as
2.6.11.12.

Is this problem with FC4 ? 

Any help in this regard will be greatly appreciated.

Thanks and Regards,
Amit Kumar

Greetings!
 
 I am looking at your config and notice that your kernel and xen are not located
in /boot directory also you are using over 512mb ram for dom0...I have never
used ovver 512 and wonder if there might be a limit..just a thought?
 
 I run 3.0 version of xen this is your config:
 title Xen 2.0 / XenLinux 2.6
 
       root(hd0,1)
       kernel /xen-2.0.7.gz   dom0_mem=720000
       module /vmlinuz-2.6.11.12-xen0   root=/dev/sda3 ro console=tty0

Here is my working config:

title Fedora Core (2.6.12.6-xen3_7.1_fc4)
        root (hd0,0)
        kernel /boot/xen.gz dom0_mem=256000
        module /boot/vmlinuz-2.6.12.6-xen3_7.1_fc4 ro root=LABEL=/ rhgb
        module /boot/initrd-2.6.12.6-xen3_7.1_fc4.img

notice i am running from boot directory (you get a message about it expecting it
in boot)

Also i am running an initrd image never tried it without one but i understand
its possible..just somthing to think about.

Thats the best i can do to help you out with my limited knowledge. Good luck and
let me know if one of these suggestions fixes your problems!

Regards,

Steven Anderson
Happy New Year!
