Or how can I get the address of hypercall page belonging to a running domU?

Please do not top post.

A domain may create an arbitrary quantity of hypercall pages, at any address of their choosing.

You have not explained why you want this information.

I want to locate the hypercall page address when creating a new domU, so as to locate hypercalls. Is it possible?

The old version of Xen contains information about hypercall page like:

xl dmesg

......

(XEN) HVM10: Allocated Xen hypercall page at 169ff000

.......

But the new edition seems to miss this information.

Correct. The information is not interesting or useful.

How can I get the similar information then?

What are you trying to do?
