[libvirt] [PATCH 1/2] storage: allow zero capacity with non-backing file to be created
In commit fbcf7da95, a change was introduced that no longer allowed defining
volumes via XML with a capacity of '0'. Because we check for info.size_arg to be
non-zero, this use-case fails. This patch allows info.size_arg to be zero if no
backing store is specified.
