Comment 2 for bug 198957

OK,
I removed the libvirt-bin package and the error appeared again after starting virtual manager and trying to connect.
An error window entitled "Virtual Machine Manager Connection Failure" pops up with the following text:
----------------------------------------------------------------------------------------------
Verify that:
 - The 'libvirtd' daemon has been started

Unable to open connection to hypervisor URI 'qemu:///session':
<class 'libvirt.libvirtError'> virConnectOpenReadOnly() failed
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/connection.py", line 306, in _open_thread
    self.vmm = libvirt.openReadOnly(self.uri)
  File "/usr/lib/python2.5/site-packages/libvirt.py", line 144, in openReadOnly
    if ret is None:raise libvirtError('virConnectOpenReadOnly() failed')
libvirtError: virConnectOpenReadOnly() failed
------------------------------------------------------------------------------------------------
Since libvirtd is in in the libvirt-bin I would think it should be required by virt-manager or one of its dependencies like python-libvirt (if I understand dependencies well enough).

Also, I notice that the libvirt0 package description has a typo too:
"library for interfacing with differeny virtualization systems"
