Re: [ovirt-devel] In-place sparsify support in VDSM

I was working on this piece of code today: https://github.com/libguestfs/libguestfs/blob/3fb35e66272ab675bb335a7ae1b... which reminded me of this email thread. The above function in libguestfs encodes which versions of qemu and which block drivers in qemu have discard support. Unfortunately it doesn't encode the NFS knowledge nor the local drive/partition business, because it's rather hard to detect those.
