Can't create a bootable VM?

looking through the forums I found this Virtual machine on LVM unable to boot

I have an lvmcluster driver and my nvme drives are all 4096 lba … that would be a very inconvenient change to make because im using these drives with NVMe over RDMA.

@stgraber
Is there anyway to convert the qcow2 images ? I would like to stay with the current logical block format.

Maybe using something like this ?
