While testing with a qcow2 with a DOS boot partition it was found that when we set the logical_block_size in the guest XML to >512 then the boot would fail in the following interminable loop: <SNIP> Trying to load: from: /pci@800000020000000/scsi@3 ... virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! </SNIP> Change the count-dos-logical-partitions Forth subroutine and the Forth subroutines calling count-dos-logical-partitions to check for this access beyond end of device error. After making the above changes, it fails properly with the correct error message as follows: <SNIP> Trying to load: from: /pci@800000020000000/scsi@3 ... virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device! virtioblk_transfer: Access beyond end of device!
