Making it larger didn't help ahci and even decreased the number of virtio-blk disks. And the 8k numbers are still higher than the documented limits (96 scsi disks and 48 or 64 ahci disks IIRC). Beside that 7.3 will get OVMF which doesn't suffer from real mode address space constrains and should be able to handle large number of disks without problems. patches sent.
