That is correct. Domain 0 in a Xen-like hypervisor is special, it
is the equivalent of the Lnux host OS in KVM world and clearly
should not be considered a VM.

The libvirt libxl driver shows 'Domain-0' in the output of 'virsh list' and does allow some operations like changing vcpu count and memory ballooning, but most operations like shutdown, reboot, save, migrate, etc are obviously not supported.
