You dont mention whether you are running the test case as root or an
unprivileged user ?  Also what config options are in your /etc/xen/xend-config.sxp
file ?

As root your test case succeeds in getting the XML.
As non-root, I see a failure on the first call - the test case is a little
bit misleading though - virDomainLookupByID is working fine - the place I 
see failure  is in the virDomainGetXMLDesc - which is because the setuid
proxy doesn't not yet support fetching the XML.

The only thing I can think ofis that you have  HTTP enabled for XenD so
that getting the XML is working, but then for some reason the proxy is
shutting down prematurely causing a failure of virDomainLookupByID. If
you could send your exact /etc/xen/xend-config.sxp file it would help me
reproduce the problem here. Oh, what Xen version and distro are you using 
And is it 32 or 64 bit would be helpful

I'm curious - what is XenAccess you mention here ? Is this some application
being developed with libvirt ?
