Hi Ralf,
you need more loop devices. So append this to dom0 kernel: max_loop=255,
if you are using grub, edit the menu.lst and put something like:
kernel module /boot/vmlinuz-2.6-xen0 root=/dev/sda1 ro max_loop=255
if you are using udev all will work all right, if not you probably must
create the devices: /dev/loopXX
Regards,
Marc

Does someone know why i can not start more than 8 vms?
Here is my config-file:
disk = [ 'phy:/dev/sdc14,hda2,w',
'file:/mnt/swapspace/c14_swap.img,hda1,w' ]
memory = 254
vcpus = 1
name = 'c14'
vif = [ 'mac=00:16:3e:1b:90:14' ]
localtime = 1
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
extra = ' TERM=xterm'
bootloader = '/usr/lib/xen/boot/domUloader.py'
bootentry = 'hda2:/boot/vmlinuz-xen,/boot/initrd-xen'
Thank you,
r. jansen
