virt-builder target fails when running virt-resize on .xz image

[vvaldez]

The following was run on Fedora 22 x86_64 with: libguestfs-tools.noarch 1:1.29.46-1.fc22 libvirt.x86_64 1.2.13.1-2.fc22 qemu-kvm.x86_64 2:2.3.0-3.fc22 virt-install.noarch 1.2.1-1.fc22

The image is installed with virt-install and the xz target completes. However, during the builder target, virt-builder fails with the following error (I added an @echo line to display the command and arguments):

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

I don't quite understand why the error affects virt-builder. Is the disk blank?

Anyway, it does sound a lot like a bug in libguestfs which I fixed upstream: https://github.com/libguestfs/libguestfs/commit/b467afb621b054e4c1e9a2f1e8814e91a395ffb7

I'll admit I haven't tried vagrant-builder on F22, only F21... It did previously work there, though.

[vvaldez]

FYI, confirmed this works in Fedora 21 (not updated) with libguestfs 1:1.28.10-1.fc21. Will try rwmjones patches on F22 next.

Closing because fixed upstream. F21 EOL
