[Qemu-devel] [Bug 1790268] [NEW] the vhd generated by qemu-img not align with MiB again.

[Andy]

Public bug reported:

I'm using this version on xenial,
address@hidden:~/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
sudo -n mount -o loop /tmp/azure_config_disk_image20180901-22672-16zxelu

/tmp/azure_config_disk_mount66c11d7a-5f2b-4ed5-b959-3b48dbc42a2a20180901-22672-1ejreat
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?
