Linux BMR - Broken grub for centos 7 with ext4 fs under onapp

OnAPP with CentOS v7.x does not handle things in a normal and consistent manner as with previous versions of CentOS/RedHat

if after recover you have a grub screen which looks like the below on image





THE FIX is fairly straight forward.  We force OnAPP to image the disk, which it will then do in a correct fomat, and then the same disk you just restored, will become bootable.

- Shutdown the VM with onapp.
- Request snapshot via oanpp for primary disk, and then create a template
- Than restore/boot the template

  This forces OnAPP to reformat the VM properly via normal tools, vs the tools they have in place for VMs booted from ISO (for some strange reason they have this setting on CentOS/RedHat v7.x)
