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-swap.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".
