  Hum, no, that's not normal, I commited this on 

Wed Oct 31 10:36:00 CET 2007 Daniel Veillard <veillard redhat com>

        * proxy/libvirt_proxy.c src/proxy_internal.[ch] src/xen_internal.c
          src/xen_unified.[ch] src/xend_internal.[ch] src/xml.[ch]: last
          patch for the library NUMA support, allow to serialize CPU pinning
          to domain configs (but won't work though proxy access), includes
          many patches from Saori Fukuta.

and we applied later another patch from you :

Mon Nov  5 11:11:45 CET 2007 Daniel Veillard <veillard redhat com>

        * src/xml.c: patch from Beth Kon to fix a problem when the
          cpuset parameter for numa uses cpu maxcpu-1

But I was hoping it was a solved problem ... I guess we need to debug this !
The string should be given to xend_parse_sexp_desc as the cpus last argument.
That argument should be computed in xenUnifiedDomainDumpXML() where it calls
xenDomainUsedCpus() to get that string.
