Just like in the linked Ubuntu writeup. I modified the following file dsims@tardis:/etc/apparmor.d/abstractions> cat libvirt- /dev/sd* rk /dev/nvme* rk dsims@tardis:/etc/apparmor.d/abstractions> libvirt- My vms are getting created on a NVMe drive. That is why I added the 2nd line. Not sure if I really needed to do that or not. But it is working now. Other than this slight mod to get around the byte 100 error, this is totally stock Leap 15.4. I have made no other mods. My knowledge of apparmor is slight at best, so no additional configuration in that area.
