While this downloads and installs the VM, the VM currently does not boot. Fixed

kvm: -device virtio-blk-pci,drive=drive-virtio0,id=virtio0,bus=pci.0,addr=0xa,bootindex=100: Cannot get 'write' permission without 'resize': Image size is not a multiple of request alignment
TASK ERROR: start failed: QEMU exited with code 1

Added a fix to convert the img to qcow2. this avoids the alignment error with RAW.

TODO:

• 1. user is root check
• 2. remove redundant copy function ( x86-64-UEFI (...) .img to ../rooter.img )
  instead use qemu-img convert to automatically convert to qcow2 and save file to ../
• 3. clean up downloaded files and unzip directory.
