P2V using dd for KVM-QEMU guest

Preface: I have certainly not exhaustively tested this process.  I had a specific need and found a specific solution that worked.

Situation:  I was issued a shiny new laptop running Red Hat Enterprise Linux 7 (with Corp VPN, certs, Authentication configuration, etc...)  The image was great, but I needed more flexibility on my bare metal.  So, my goal was to P2V the corporate image so I could just run it as a VM.

* Remove corporate drive and install new SSD
* install corp drive in external USB-3 case
* Install RHEL 7 on new SSD
* dd old drive to a disk-image file in a temp location which will be an image which is the same size as your actual drive (unless you have enough space in your destination to contain a temp and converted image)
* convert the raw disk-image to a qcow file while pushing it to the final location - this step should reduce the disk size - however, I believe it will only reduce/collapse zero-byte blocks (not just free space - i.e. if you delete a file, it may, or may not change the blocks back to zero)

dd if=/dev/sdb of=/mnt/RHEL7-CSB.raw
qemu-img convert -f raw -O qcow2 /mnt/RHEL7-CSB.raw /var/lib/libvirt/images/RHEL7-CSB.qcow2
chown qemu:qemu /var/lib/libvirt/images/RHEL7-CSB.qcow2 && chmod 0664 /var/lib/libvirt/images/RHEL7-CSB.qcow2    
restorecon -RFvv /var/lib/libvirt/images/RHEL7-CSB.qcow2

Create a new VM using virt-manager and point it at your new qcow2 file. (It will fail to boot at this point). Click the light-bulb and change the Disk from Virtio to IDE. (try booting at this point). If it still does not boot... edit the boot string and remove the hint for UEFI or the hint for baremetal (I don't actually know which one fixed the issue) "--hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2"

qemu-img convert -f raw -O qcow2 centos7.img centos7.qcow2  

If not obvious, my original image was RHEL7 and the Hypervisor was also RHEL 7 using KVM. From my experience, other hypervisors seem more accepting of different disk image types, etc...
