## Motivation Background:
The new SL Micro 6.1 PowerPC images are created with 2 flavors: 512 and 4096 block sizes. The reason is to allow users pick one or the other depending on the physical storage to be used. In qemu, both can be used, but an additional flag needs to be specified in the `device` entry:
`-device xyz,logical_block_size=4096,physical_block_size=4096`
So, as an example, this is extracted from an openQA job directly:
```
> /usr/bin/qemu-img create -f qcow2 -F raw -b /var/lib/openqa/pool/1/SL-Micro.ppc64le-6.1-Base-ppc-4096-Build3.12.raw /var/lib/openqa/pool/1/raid/hd0-overlay0 32G`
> /usr/bin/qemu-img create -f qcow2 -F qcow2 -b /var/lib/openqa/pool/1/ignition.qcow2 /var/lib/openqa/pool/1/raid/hd1-overlay0 10485760`
> /usr/bin/qemu-system-ppc64 -device VGA,edid=on,xres=1024,yres=768 -g 1024x768 -only-migratable -chardev ringbuf,id=serial0,logfile=serial0,logappend=on -serial chardev:serial0 -audiodev none,id=snd0 -device intel-hda -device hda-output,audiodev=snd0 -global isa-fdc.fdtypeA=none -m 1024 -machine usb=off -cpu host -netdev user,id=qanet0 -device virtio-net,netdev=qanet0,mac=52:54:00:12:34:56 -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-pci,rng=rng0 -boot order=c -device nec-usb-xhci -device usb-tablet -device usb-kbd -smp 1,threads=1 -enable-kvm -no-shutdown -vnc :91,share=force-shared -device virtio-serial -chardev pipe,id=virtio_console,path=virtio_console,logfile=virtio_console.log,logappend=on -device virtconsole,chardev=virtio_console,name=org.openqa.console.virtio_console -chardev pipe,id=virtio_console_user,path=virtio_console_user,logfile=virtio_console_user.log,logappend=on -device virtconsole,chardev=virtio_console_user,name=org.openqa.console.virtio_console_user -chardev socket,path=qmp_socket,server=on,wait=off,id=qmp_socket,logfile=qmp_socket.log,logappend=on -qmp chardev:qmp_socket -S -device virtio-scsi-pci,id=scsi0 -blockdev driver=file,node-name=hd0-overlay0-file,filename=/var/lib/openqa/pool/1/raid/hd0-overlay0,cache.no-flush=on -blockdev driver=qcow2,node-name=hd0-overlay0,file=hd0-overlay0-file,cache.no-flush=on,discard=unmap -device virtio-blk,id=hd0-device,drive=hd0-overlay0,bootindex=0,serial=hd0 -blockdev driver=file,node-name=hd1-overlay0-file,filename=/var/lib/openqa/pool/1/raid/hd1-overlay0,cache.no-flush=on -blockdev driver=qcow2,node-name=hd1-overlay0,file=hd1-overlay0-file,cache.no-flush=on,discard=unmap -device virtio-blk,id=hd1-device,drive=hd1-overlay0,serial=hd1
```
So, the line that says
`-device virtio-blk,id=hd0-device,drive=hd0-overlay0,bootindex=0,serial=hd0`
would become
`-device virtio-blk,id=hd0-device,drive=hd0-overlay0,bootindex=0,serial=hd0,logical_block_size=4096,physical_block_size=4096`
For reference: https://bugzilla.suse.com/show_bug.cgi?id=1227707#c6
A possible solution, would be to create a new variable `HDD_1_OPTIONS` (or similar) which appends the value of this variable to `-dev`.
## Acceptance criteria
* TBD
## Suggestions
* Add an option in openQA using variables to append this configuration to the block device
