According to this page:
http://www.howtoforge.com/perfect_setup_xen3_debian_p5
You need to add max_loop=N (where N is the number of virtual
machines you want x 2) to your module line in grub.conf
But, oddly, I'm using CentOS-5 x86_64, and I have dom0 plus
five virtual machines running, and I did not change any
setting, config file, and I don't have max_loop in my
grub.conf -- it's just a default install & setup.
