Inexplicably the sanlock code all got placed under the GPLv2-only, so libvirt's use of sanlock introduces a license incompatibility. The sanlock developers have now rearranged the code such that there is a 'sanlock_client.so' which is LGPLv2+ while their daemon remains GPLv2-only. To use the new client library we need to call the new sanlock_init and sanlock_align APIs instead of sanlock_direct_init and sanlock_direct_align. These APIs calls are now routed via the sanlock daemon, instead of doing direct I/O calls to disk. For all this we require sanlock >= 1.8 * configure.ac: Check for sanlock_client.so instead of sanlock.so and fix various comments * libvirt.spec.in: Mandate sanlock >= 1.8 * src/Makefile.am: Link to -lsanlock_client * src/locking/lock_driver_sanlock.c: Use sanlock_init and sanlock_align
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.
