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

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...

thanks.

What hypervisor are you trying to use? Xen? KVM ?

I'm using the same kernel with Xen 4.4.1 rpms.
