Comment 5 for bug 222938

I can successfully connect to a local (qemu) machine using virt-manager.

I cannot connect to a remote machine (xen) using virt-manager.

I can connect via virsh to the same remote machine using xen+ssh. The same method does not work for virt-manager. The error reported is the same as above:

  Unable to open a connection to the libvirt management daemon.

  Verify that:
   - The 'libvirt-bin' package is installed
   - The 'libvirtd' daemon has been started

The attempt to connect via virt-manager kills libvirtd on the remote server. It dies with error:
 Apr 18 16:05:19 dram kernel: [ 2510.448100] libvirtd[5605] trap divide error rip:7f4ad963467a rsp:7fffe20ed730 error:0
