Thanks for the info.  

I am trying to connect to the Xen hypervisor, via a localhost connection defined in the virt-manager configuration.

here is the detail provided in the error dialog:

Unable to open a connection to the Xen hypervisor/daemon.

Verify that:
 - A Xen host kernel was booted
 - The Xen service has been started

internal error: DBus support not compiled into this binary

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/connection.py", line 1168, in _open_thread
    self.vmm = self._try_open()
  File "/usr/share/virt-manager/virtManager/connection.py", line 1152, in _try_open
  File "/usr/lib64/python2.6/site-packages/libvirt.py", line 105, in openAuth
    if ret is None:raise libvirtError('virConnectOpenAuth() failed')
libvirtError: internal error: DBus support not compiled into this binary


The hypervisor and VM’s work.  If i start and manage VMs with virsh, the work fine.  it just is the virt-manager that seems broken, but that is important for my operation.

i just applied the patches to a second machine - just in case it was something about the first one - and the same results.

i am not as versed in python debugging as i would like to be, so this will be a challenge.  it sure seems like the issue is in the libvirtd library from the error messages - 
but i will keep poking at it as time permits and post here if i have any answers...
