Hi, I created the attached patch to have libvirt create images with format 2 by default, this would simplify the CloudStack code and could also help other projects. The problem with libvirt is that there is no mechanism to supply information like order, features, stripe unit and count to the rbd_create3 method, so it's now hardcoded in libvirt. Any comments on this patch before I fire it of to the libvirt guys? -- Wido den Hollander 42on B.V. Phone: +31 (0)20 700 9902 Skype: contact42on
