[Fedora-xen] Help: creating a rawhide guest os

[Ranganathan, Shobha]

You may want to build your xen sources with pae=y.
Fedora core 6 are all PAE kernels.

Subject: [Fedora-xen] Help: creating a rawhide guest os

My dom0 is working fine and I was able to fire a friend's ubuntu image.
But my problem is that I can't create a guest fedora os with
xen-guest-install.py
see: https://www.redhat.com/archives/fedora-xen/2006-June/msg00108.html

Yes, I still can't make one :(

So I started making my own guest os by hand, which appears to be wrong:

This is my procedure:

mkdir -p /xen-images/mnt

dd if=/dev/zero of=/xen-images/guest_base.img bs=1024k count=5000
dd if=/dev/zero of=/xen-images/guest_base-swap.img bs=1024k count=500
chmod 640 /xen-images/guest_base*
mkfs.ext3 /xen-images/guest_base.img
mkswap /xen-images/guest_base-swap.img
mount -o loop /xen-images/guest_base.img /xen-images/mnt
anaconda --method=nfs://var/www/bordeaux/ --rootpath=/xen-images/mnt/
cp -dpR /lib/modules/2.6.17-1.2187_FC5xen0/ /xen-images/mnt/lib/modules/

I've added
/dev/hda1               /                       ext3
defaults,errors=remount-ro    0 1
/dev/hda2               swap                    swap    sw
to /xen-images/mnt/etc/fstab&

umount /xen-images/mnt
cd /boot

cp initrd-2.6.17-1.2187_FC5xen0.img initrd-guest.img
cp vmlinuz-2.6.17-1.2187_FC5 vmlinuz-guest.img

cd /etc/xen/
kwrite xm-fc6 &

name = "xm-fc6"
memory = "256"
kernel = "/boot/vmlinuz-guest.img"
ramdisk = "/boot/initrd-guest.img"
vif = ['bridge=xenbr0']
disk =
['file:/xen-images/guest_base.img,hda1,w','file:/xen-images/guest_base-s
wap.img,hda2,w']
ip = "192.168.0.101"
netmask = "255.255.255.0"
gateway = "192.168.0.1"
hostname = "baseimage"
root = "/dev/hda1 ro"
extra = "4"

on_reboot   = 'restart'
on_crash    = 'restart'

xm create xm-fc6 -c

I fell on
Using config file "xm-fc6".
Error: (9, 'Bad file descriptor')

cat /var/log/xend-debug.log

ERROR: PAE-kernel on non-PAE host.

line 1311, in initDomain
    raise VmError(str(exn))
VmError: (9, 'Bad file descriptor')


Any one can point to me what Im doing wrong and a solution if possible
to remedy this ? :)
