We provide (via our FTP) two Centos-virtualBox images that starts ok in VirtualBox. The machines are in .ova format.
This images have now 16Gb of size, we need it to be resized to 35 Gb each one.
The freelancer sends us the .ova resized images (we provide the FTP) ready to be imported in the original host.
When imported the two images to VirtualBox and starteb both ok, the job is done.
