Dear.

I've run into troubles with the resize of partitions and file injection;
using libvirt and raw images.

According to https://bugs.launchpad.net/nova/+bug/929005 file injection
into images only works in the following situations:
  1.- whole disk image -> inject to partition 1.
  2.- separate kernel and ramdisk -> inject without partitions.

In situation 1 (i.e. using whole disk images, with one partition
inside) the file injection works fine, the disk is resized to the
actual size, but the partition is not extended. This is because the
'extend' function in 'nova/virt/disk/api.py' executes 'qemu-img',
'e2fsck' and 'resize2fs' in a row, assuming that there are no
partitions at all.

In situation 2 (i.e. using whole disk images) if there is no kernel
and ramdisk (but the file is a self-contained disk with an appropriate
kernel) file injection does not work, but the resize works fine (since
there are no partitions and the fsck and resize work as expected).

Shouldn't the file injection be extended so as to make it work in any
situation? That is, add injection without partitions and without
kernel/ramdisk.

Shouldn't the resize of disk take into account that it might be a disk
with a (single) partition inside? This would imply dealing with the
partitions (that is, delete and recreate them to the appropiate size).

Regards,
