Reducing size of ova images


#62

Qubes uses fstrim.

https://github.com/QubesOS/qubes-linux-template-builder/blob/master/cleanup_image#L24

If we run that before and/or after zerofree (or vice versa) could we further reduce Whonix image sizes?

Hi Patrick. I didn’t know this method. I can give it a try.
Cheers

Hello

Back to the forum after a long summer pause…

I did a try with a Whonix-Gateway (current, 14) build and did not notice any difference.

I proceeded as follows:

  • I ran manually steps 1100 to 2300
  • After rebooting the machine I mounted the .raw image using /home/user/Whonix/help-steps/mount-raw
  • Then I ran sudo /sbin/fstrim -v /home/user/Whonix-Gateway_image
  • After that I proceeded with the last build-steps as usual

The final .ova size is 937 MB, exactly the same size as without the fstrim command.

By the way, I notice that using the current github version results in a 14.0.0.8.1-19 version, whereas the official download version is currently 14.0.0.7.4, and only weighs 850 MB. Is there any substantial difference between the two versions, and why this size increase?

One more little thing: the values for .ova files must be updated here according to their new value: https://www.whonix.org/wiki/Template:DownloadTable#
