Re: [Xen-users] RuntimeError: domUloader

[Marc Patino Gómez <mpatino@xxxxxxxxxxxx>]

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
