[Qemu-discuss] Block format 'qcow2' used by device 'drive-virtio0' doesn't support the option 'physical_block_size'

[Hendrik Visage]

Good day,

 Anybody able to guide me the combinations, etc. when and where these
are supported?
I'm having performance issues on 512e advance format/4Kb disks, and
the symptoms for me tells me that I'm hitting the read-modify-write
problems as the VMs report 512/512 for the virtio block devices, and I
want to modify that to 4k sector sizes.
