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 ?
I'm running as root. My xend-config is attached.
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.
In my case, the failure is with virDomainLookupByID. For example, I get the following output: [root@guinness examples]# ./test (0) (null) ERROR: Failed to find Domain 1 Failed on second try [root@guinness examples]#
reproduce the problem here. Oh, what Xen version and distro are you using And is it 32 or 64 bit would be helpful

My machine is running FC5 (32-bit). When I tested the two libvirt versions, I build both directly from source using the standard (./configure ; make ; make install).
I'm curious - what is XenAccess you mention here ? Is this some application being developed with libvirt ?
Yes, XenAccess is a project that I'm working on to provide introspection for Xen. Currently, I use libvirt to obtain the kernel version of a running domain, but may use it for more info in the future. Details available here: http://xenaccess.sourceforge.net/ Thanks, bryan
