Mini ISO #1030

Closed kroese closed 5 months ago

kroese commented 5 months ago

Im distributing the drivers ISO along my application, but it's pretty huge (> 500 MB) and even compressed its still a couple of hundred MBs.

As far as I can tell the bulk of this space is occupied by the PDB (debugging files) which are not really necessary for production use.

Would it be an idea to generate also a tiny ISO with all stuff removed that is not strictly required?

Unfortunately we don't build vfd images any more. But customising and rebuilding the virtio-win iso can be easily done by using mkisofs utility https://github.com/virtio-win/virtio-win-pkg-scripts/blob/master/virtio-win.spec#L142

Thanks! Three more questions:

Is there anything else that can safely be removed, aside from the .PDB files?
If I create a Github repo to do automatic builds of this mini-iso, am I allowed to distribute the binaries in that repo? I know its opensource, but maybe there is a licensing restriction about that?
How does the versioning work? If I look at the tagnames for the repo, the tag is at 260, but the binaries are version 240? There does not even exist a tag mm240? Normally when I do automatic builds for other projects I retrieve the URL to the binaries based on the tags in the source repo, but for this project that seems not possible.

Do you want to rebuild the iso image only or repackage the entire rpm?
It shouldn't be a problem with the binaries redistribution as it stated in our LICENSE file https://github.com/virtio-win/kvm-guest-drivers-windows/blob/master/LICENSE#L6
we trying to keep the tag to build map as much accurate and updated as possible https://github.com/virtio-win/kvm-guest-drivers-windows/wiki/Builds-and-tags-mapping

Best, Vadim.

I finished my project, and decided to name it.. drumroll

Virtiso is a very minimal image with only AMD64 support for installing Windows machines. I managed to strip it from 600 MB down to only 23.7 MB, which is a lot more reasonable.

Changelist

Stripped ARM64/i386/x86 drivers
Stripped all .PDB (debug symbol) files
Stripped Guest Agent and Guest Tools

I plan to maintain these builds together with the official builds. So I guess this issue can be considered solved now.
