      What were you trying to do that didn't work?

      Setting <blockio logical_block_size='512' physical_block_size='512'/> for <disk device='lun'> a doesn't get rejected at XML validation and thus gets rejected by qemu with a sub-optimal error message:

      $ virsh start cd
error: Failed to start domain 'cd'
error: internal error: QEMU unexpectedly closed the monitor (vm='cd'): 2026-02-03T13:45:30.273503Z qemu-system-x86_64: -device {"driver":"scsi-block","bus":"scsi0.0","channel":0,"scsi-id":0,"lun":0,"drive":"libvirt-1-format","id":"scsi0-0-0-0","logical_block_size":512,"physical_block_size":512}: Property 'scsi-block.physical_block_size' not found
