When virStorageBackendLogicalCreateVol() creates a snapshot for a logical volume with backingStore element, it fails with the message below: 2013-01-17 03:10:18.869+0000: 1967: error : virCommandWait:2345 : internal error Child process (/sbin/lvcreate --name lvm-snapshot -L 51200K -s=/dev/lvm-pool/lvm-volume) unexpected exit status 3: /sbin/lvcreate: invalid option -- '=' Error during parsing of command line. This is because virCommandAddArgPair() uses '=' to connect the two parameters, it's unsuitable for -s option of the lvcreate.

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.
