I got that to work by trying DOMIDs starting with 0 until the read succeeds, but that's kind of gross. I can think of some less gross methods to find my domid, but I'd still be glad to hear suggestions. Would you like to have an interface for obtaining one's UUID? What about adding a XENVER_get_uuid code to HYPERVISOR_xen_version()? _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
