You can launch domUs without config file. In your case, you can read domU configuration parameters from database and them generate "xm create" command dynamically

Example.
                 xm create /dev/null ramdisk=initrd.img \
                    kernel=/boot/vmlinuz-2.6.12.6-xenU \
                    name=ramdisk vif='' vcpus=1 \
                    memory=64 root=/dev/ram0

Aren't the domu config files in /etc/xen just python source fragments?
