So I have an existing working VM and I also have a .dd image of a bootable USB drive. 

 

How would I go about modifying my existing XML file to boot this .dd image file before my hard drive.

 

My two use cases are to boot a clover image before going into OS X and my second use case is the need to boot the live gparted .iso file.

 

Example OS X XML  (In this example I believe I need to delete the kernal line as that is envoking the chameleon bootloader).

So I have been trying different things...for the gparted .iso case I replaced the ubuntu install .iso with the gparted live cd.iso and changed the boot order accordingly and I am able to boot gparted...however after answering the setup questions, about keyboard, language etc, It gets to video settings and then stops.  Attached is a screenshot of where it ends.  I am using VNC for the graphics...maybe I should try passthrough?

 

Maybe I am going in the wrong direction.  I created an ubuntu LTS VM and the initial size was 5Gb and its too small.  I want to increase it to 10Gb.  I have made the change in the unraid VM to 10 Gb.  How do I resize my file system to get the additional 5GB I added?  I know how to do this with my windows VMs...I assumed I needed to run gparted to make the change...but could be wrong.

 

Any suggestions would be greatly appreciated.
