 Hello again!

 Unfortunately it doesn't work...

 Here is the error: "Flavor's disk is too small for requested image. 
 Flavor disk is 21474836480 bytes, image is 53687091200 bytes.]."

 This is on an image that was taken when the flavor had root with 50GB 
 and tried to upload it using a flavor of 20GB.

 The filesystem uses around 2-3GB and I had specified with the 
 "--min-disk 5" parameter to be able to spawn on 5GB or more flavors.

 Here is the output from "image show" command

 The only thing that I didn't do was to use the "save" command although 
 I don't know if that could make a difference!

 I 've just went to "/var/lib/glance/images" and taken directly from 
 there the file that was corresponding to the image I wanted.
 Do you believe that by "saving" it would make any difference??

 Any other ideas that I can try???


 All the best,

 G.
