Hello, I'm trying to achieve the equivalent of libvirtd "<blockio logical_block_size='4096' physical_block_size='4096'/>" with oVirt and I'm having a hard time. I created a 4K luhn on my SAN and it is seen as a 4K disk on the host, but within the VM, fdisk show 512 bytes for the sector size. Is there a way/tips to delegate raw-data non-bootable partition with 4K sector-size to oVirt virtual machines ? I'm running 3.5 but I'm okay with a solution in 3.6. Thanks Florian
