Thank you. The outputs show the first 256 bytes of nvd0 and nvme0n1
match. It might be worth checking a larger range (e.g. 1MB), but I'd
expect that would match as well. Out of curiosity, on the host, what
output do you get from:
# nvmecontrol identify nvme0ns1 | grep "LBA Format"
and on the guest:
# nvme id-ns /dev/nvme0n1 | grep lba
