Or it uses text files in /var/lib/xen for domain configs.

We haven't changed anything in Xen in this regard. In Xen 3.0.3 and
ealier the only place to store config files was in /etc, and XenD had
no concept of inactive domains. In Xen 3.0.4 or later, XenD can directly
manage inactive domains, storing their configs in /var/lib/xen/. IF
libvirt detects a new enough XenD it will use its inactive domain
management capabilities instead of putting configs in /etc, since this
gives access to a greater level of functionality.
