Hello devs,
please see issue:
https://github.com/virtio-win/kvm-guest-drivers-windows/issues/446
Short summary: When using encrypted disks with qemu (using dm-crypt) and
pass that through LIO/vhost to qemu (via virtio-scsi) the following code
is hit:
https://elixir.bootlin.com/linux/v5.3.18/source/drivers/md/dm-crypt.c#L1251
I am not familiar with the specification/contract of "bio". So I am not
sure if the enforced alignment is legitimate.
Under Windows you cannot even initialize a disk because it wants to
write sector 0 (count = 1) at offset 432.
Could some expert please comment?
Regards Andreas
