[Xen-users] Booting problem with compiled xen 3.3.0/linux- source
Hi All,

I am trying to compile Xen 3.3.0 source code which downloads updates from
mercurial repository.
I am trying to modify the CPU scheduler, but before i make any changes i
need to test it by installing it from source.

OS: Fedora 8 Linux

I compiled the source code by using

[root@localhost xen-3.3.0]# make world
[root@localhost xen-3.3.0]# make install
[root@localhost xen-3.3.0]# depmod
[root@localhost xen-3.3.0]# mkinitrd initrd-

then i moved "initrd-" to /boot

edited the grub.conf

title WindowsXP
rootnoverify (hd0,0)
chainloader +1
title Fedora-base (
root (hd0,5)
kernel /vmlinuz- ro root=LABEL=/ rhgb quiet
initrd /initrd-
title Fedora (2.6.21-2950.fc8xen)
root (hd0,5)
kernel /xen.gz-2.6.21-2950.fc8
module /vmlinuz-2.6.21-2950.fc8xen ro root=LABEL=/ rhgb quiet
module /initrd-2.6.21-2950.fc8xen.img

kernel /xen-3.3.0.gz
#module /vmlinuz- ro root=/dev/sda8 console=tty0 1
module /vmlinuz- ro root=LABEL=/ console=tty0
module /initrd-

When i select 4th option, i get these messages while booting,

(XEN) Dom0 has maximum 1 VCPUs
(XEN) Initrd len 0x6e8600, start ar 0xc0460000
(XEN) Scrubbing Free RAM: .........done.

Red Hat nash version 6.0.19 starting

setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc : No such file or directory
setuproot: error mounting /sys : No such file or directory
switchroot: mount failed: No such file or directory

After this the system hangs....

it seems it is unable to mount root filesystem. What changes needs to be
done to make things work.

Any suggestions.

Thanks in advance.
