Note this patch requires a non-upstream qemu patch that I've been experimenting with. See qemu-devel list. Rich.

This series improves ceph rbd support in libguestfs. It uses the servers list, adds support for a custom username, and starts to add support for custom secret.

These patches contain the beginnings of discard (a.k.a. trim or unmap) support. This will allow us to change virt-sparsify to work on disk images in-place (instead of using slow & inefficient copying). The approach used is to add an optional 'discard' parameter to add-drive. It has 3 possible settings: - 'disable' : the default, no discard is done - 'besteffort' :

This still isn't working at the moment. See: http://marc.info/?t=139457409300003&r=1&w=2 This set of patches: - Adds new APIs to support discard in libguestfs. - Adds discard support to virt-format. - Adds discard support to virt-sysprep. - Implements virt-sparsify --in-place. Rich.
