Cole Robinson 29a2a91187 storage: lvm: lvcreate fails with allocation=0, don't do that 
On F17 at least, this command fails:

$ sudo /usr/sbin/lvcreate --name sparsetest -L 0K --virtualsize 16384K vgvirt
  Unable to create new logical volume with no extents

Which is unfortunate since allocation=0 is what virt-manager tries to use
by default.

Rather than telling the user 'don't do that', let's just give them the
smallest allocation possible if alloc=0 is requested.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
