Re: [ovirt-devel] ovirt-appliance (today) is 1.5G...
We may also want to do this with Node/RHV-H eventually (since the updates there are already 500MB). I don't think we currently ship deltarpm on RHV-H, but it's a very small addition. The question is whether makedeltarpm can actually do anything meaningful with something which is already a sparsified image wrapped in an RPM, but I'll test...

I'm sure it was less just days ago, but now[1] it is again quite big. 4.0's is 'only' 1G in size[2]. Which anyway raises the question - should we provide delta RPMs for it?
Thanks, Y.

Just a comment -- Cursory testing shows that makedeltarpm is not good at this -- it doesn't know how to examine the contents of the OVA (or they're too different). The delta RPM between 4.0 (~1GB) and 4.1-pre (~1.45GB) is 1.41GB. With or without -r It may take a little more tweaking, but the options for "makedeltarpm" are pretty sparse. We can try talking to the maintainer this week also... On Sun, Oct 9, 2016 at 4:00 PM, Ryan Barry <rbarry@redhat.com> wrote:

Yep - deltarpm uses bsdiff and they struggle to diff so large binary files. If we had a different deliverable - like a tarball - then bsdiff could make sense. But a qcow is not an ideal format for doing a binary diff. Btw a squashfs is also not suitable for bdiff. - fabian
