This is done by "vfr_ipaddr" during domain creation, or you can add/delete addresses latter using the xc_dom_control.

Guest can only setup an interface with address that is ''granted'' to it? ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.

To paraphrase a common saying uttered by nightclub doormen: "if your name''s not on the list, you don''t go on the wire." ;-) Hence, Xen provides secure isolation of domain''s IP addresses. The next version of Xen will also provide L4 port-space isolation, enabling two or more domain to share a single IP via something akin to RSIP.
