We used to look at the librbd code version and depending on that we would invoke rbd_create3() or rbd_create(). Since librbd version 0.67.9 we can however tell RBD that it should create rbd format 2 images even if we invoke rbd_create(). The less options we pass to librbd, the more we can lean on the sane defaults it uses. For rbd_create3() we had things like the stripe count and unit hardcoded in libvirt and that might cause problems down the road. Signed-off-by: Wido den Hollander <wido@widodh.nl>
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.
