The latter looks unexpected, but is is becase qemu is not passing through the qemu physical_block_size attribute to any of the nvme settings Linux interprets as such for NVMe (NVMe doesn't actually have the concept of a physical block size, unlike SCSI/ATA): root@testvm:~# nvme id-ns -H /dev/nvme0n1 | grep npw npwg : 0 npwa : 0 root@testvm:~# nvme id-ns -H /dev/nvme0n1 | grep naw nawun : 0 nawupf : 0 root@testvm:~# nvme id-ctrl -H /dev/nvme0 | grep awupf awupf : 0 but as said multiple times, that should not really matter - the logical block size is the granularity of I/O, the physical block size is just a performance hint.
