[Pkg-libvirt-maintainers] Bug#505577: libvirt-bin: libvirt throws exception on disk allocation

[Ritesh Raj Sarraf]

Package: libvirt-bin
Version: 0.4.6-4
Severity: important

As per the readme, any user that is part of libvirt group should be able to access/use/create guest VMs.

With the above in place, when trying to create a VM, I get the following exception:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/create.py", line 303, in forward
    if(self.validate(notebook.get_current_page()) != True):
  File "/usr/share/virt-manager/virtManager/create.py", line 1008, in validate
    vmmutil.build_default_pool(self._guest.conn)
  File "/usr/share/virt-manager/virtManager/util.py", line 54, in build_default_pool
    (DEFAULT_POOL_PATH, str(e)))
RuntimeError: Couldn't create default storage pool '/var/lib/libvirt/images': Could not start storage pool: cannot open path '/var/lib/libvirt/images': No such file or directory

Indeed, there's no "images" folder. And one is not created because /var/lib/libvirt is owned root.root.
Simply changing the ownership to root.libvirt and g+wx fixed the problem.
