Hi,

As we know, a domainU's domid may change after system reboots. Does Xen provide a persistent identifier for each domU? I tried UUID, but UUID also changes across reboots. Any idea on this? If Xen does provide such a mechanism to persistently identify a domain U? What is it?

Which UUID do you mean? The one that xm list --long shows you as the UUID for the domain certainly shouldn't change across reboots (it doesn't for me).
