Motivation¶

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`

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
