You may also need to be a member of the "disk" group too

The goal is to be able to run windows off a native NVMe drive so one can run it as a VM and
as a dual boot configuration

To install windows on a raw device, you'll require the virtio scsi driver. Why? because the raw
device is "attached" by the virtual host bus adapter. Even if you add the device like I show
below, windows won't see it until you add that virtio driver during the install.

Simply create another CDROM device to mount this iso so you can access it from the installer

Finally, the virsh xml snippet:

# virsh edit win10

    <disk type='block' device='disk'>
      <driver name='qemu' type='raw' cache='unsafe'/>
      <source dev='/dev/nvme1n1p1'/>
      <target dev='sda' bus='virtio'/>
      <boot order='2'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
    </disk>

Just pick a slot on the pci bus that's available, it doesn't matter

It probably would be a good idea to create a custom image that mixed in the virtio 
and spice drivers.
