I'm having a problem getting Condor to start up a KVM virtual machine in Condor. I posted an email before, and with advice from a few people, I was able to sort out my KVM problems. But now, whenever I run a vm universe job, the condor_vm-gahp fails with the following error:

Now, I have adjusted /etc/libvirt/libvirt.conf to allow the libvirt group to access the libvirt rw socket, and I added the users root, rjansen, and condor to that group.
Additionally, I can connect just fine (as root and rjansen) to qemu:///session, through virsh, and through the libvirt C library using example code from the qemu website. In fact, the code I use to connect to the library in the example program is essentially the same as the code on line 989 in xen_type.cpp, which is failing.
I'm not sure if I'm doing something wrong with Condor or something wrong with KVM/libvirt, but I'd like to get this working.
Does anyone have any ideas on how to fix this problem?
