You are being limited by the amount of loop devices available.   
Depending on your system, e.g. Centos, add `options loop max_loop=32`  
to /etc/modprobe.conf and give your dom0 a restart.

It will boot up and generate /dev/loop0-31 rather than the default / 
dev/loop0-7

Thanks all.
I don''t know why, but the solution of change the modprobe.conf file not
work
for my FC5-x86_64 dom0.
For me, the solution was adding loop_max=32 to the grub.conf

So, my grub.conf file looks like:

title Xen 3.0 / XenLinux 2.6
 kernel /xen-3.0.gz dom0_mem=262144
 module /vmlinuz-2.6-xen ro root=/dev/XenVol/Root rhgb quiet max_loop=32
 module /initrd-2.6.16.29-xen


Thanks all, for your support.

Regards
Luis
