It's a module: (on Dom0 and DomU)
srv-ux-0014:/etc/xen/vm # zcat /proc/config.gz | grep BLK_DEV_LOOP
CONFIG_BLK_DEV_LOOP=m

for dom0 "max_loop=64" works
for domU "extra = "3 TERM=xterm max_loop=64"" this does not work.

When it's a module you need to make sure it's loaded with this param.
The module doesn't use the parameter from the kernel command line.
You have to load the module for example like
modprobe loop max_loop=64
or add sometthing like that in your module config.

The tap:aio itamar wrote about might also work - but on some settings
we had problems with the stability of this, and not sure if all
distribution packages already support this.
