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' :

v1 -> v2: - Rebase on top of Pino's version work. Two patches went upstream, these are the two remaining patches. Note the generation number is still inside the qemu.stat file. We could put it in the filename, I have no particular preference. Rich.

Hi, this adds an helper version struct, and uses it in the backends (for the libvirt and qemu versions) and inspection code. This also moves common code to that, so it is not repeated in many places. This should help with the small refactoring proposed with https://www.redhat.com/archives/libguestfs/2016-May/msg00070.html Thanks, Pino Toscano (2): src: start unifying version handling

Doing qemu feature detection in the direct backend takes ~100ms because we need to run `qemu -help' and `qemu -devices ?', and each of those interacts with glibc's very slow link loader. Fixing the link loader is really hard. Instead memoize the output of those two commands. This patch series first separates all the code dealing with qemu into a separate module (src/qemu.c) and

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. This is now working, after fixing the rather stupid bug in fstrim. I've pushed the ones which were ACKed previously + the fstrim fix. Rich.

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.
