the vhd generated by qemu-img not align with MB again.
I'm using this version on xenial,
andy@bastion:~/temp$ qemu-img -h
qemu-img version 2.5.0 (Debian 1:2.5+dfsg-5ubuntu10.31), Copyright (c) 2004-2008 Fabrice Bellard
steps to repro:
dd if=/dev/zero of=/tmp/azure_config_disk_image20180901-22672-16zxelu bs=1048576 count=24
mkfs.ext4 -F /tmp/azure_config_disk_image20180901-22672-16zxelu -L azure_cfg_dsk

qemu-img convert -f raw -O vpc -o subformat=fixed,force_size /tmp/azure_config_disk_image20180901-22672-16zxelu papapa2.vhd
unfortunately the papapa2.vhd size is 25166336!=25165824 which means it's not aligned in MiB.
could you please help?
last bug report and fixed is https://bugs.launchpad.net/qemu/+bug/1490611
and even the format is raw:
andy@bastion:~/temp$ qemu-img info papapa2.vhd
image: papapa2.vhd
file format: raw
virtual size: 24M (25166336 bytes)
disk size: 152K
It is -o subformat=fixed which breaks the file format detection
