[Pkg-libvirt-maintainers] Bug#777548: libguestfs-tools: virt-builder fails with --size option

[Jean-Baptiste Rouault]

Package: libguestfs-tools
Version: 1:1.28.1-1
Severity: normal
Tags: patch

Dear Maintainer,

When running virt-builder with --size option, the command fails to resize the disk image.
Here is the program output :
jb at debian:~$ virt-builder debian-7 -o debian7.img --size 8G
[   1.0] Downloading: http://libguestfs.org/download/builder/debian-7.xz
[   2.0] Planning how to build this image
[   2.0] Uncompressing
[   4.0] Resizing (using virt-resize) to expand the disk to 8.0G
virt-resize: error: libguestfs error: copy_device_to_device: /dev/sdb2: 
write: No space left on device

If reporting bugs, run virt-resize with debugging enabled and include the 
complete output:

  virt-resize -v -x [...]

It looks like the following upstream commit fixes the problem, but I didn't try to
apply it to the current version in Jessie :
