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. https://bugzilla.redhat.com/show_bug.cgi?id=866481
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.
