Hello,
I'm using *virt-sparsify* for compressing image file
[ash2]
jenkins@b-imagebuilder-worker-r13h17-prod:~/workspace/imagebuilder/packer/output$
virt-sparsify --compress
/data/home/jenkins/workspace/imagebuilder/packer/output/packer-vm.qcow2
/data/home/jenkins/workspace/imagebuilder/packer/output/packer-vm.qcow2.sparsified
Input disk virtual size = 41943040000 bytes (39.1G)
Create overlay file in /data/tmp/ to protect source disk ...
Examine source disk ...
Fatal error: exception Guestfs.Error("guestfs_launch failed.
This usually means the libguestfs appliance failed to start or crashed.
See http://libguestfs.org/guestfs-faq.1.html#debugging-libguestfs
or run 'libguestfs-test-tool' and post the *complete* output into a
bug report
Here is *libguestfs-test-tool* output
http://pastebin.com/raw/anuu6wkh
I would really appreciate any help or hint
Have a nice day,
Illia Svyrydov

This was fixed upstream in: https://github.com/libguestfs/libguestfs/commit/34439a04f1921c4e5ece1077570b0f036a64c7ee but you should be able to work around it by dropping a file into /usr/lib/guestfs/supermin.d that contains the required symlink target plus all parent directories. eg. If /tmp (on the host) is a symlink to /foo/bar/baz then you'd do something like this (as root): echo > /usr/lib/guestfs/supermin.d/zz-tmp-fix <<EOF / /foo /foo/bar /foo/bar/baz EOF update-guestfs-appliance I should note that this Ubuntu version of libguestfs is both ancient and has a number of serious bugs, including security issues: https://bugs.launchpad.net/ubuntu/+source/libguestfs/+bug/1433750 https://bugzilla.redhat.com/show_bug.cgi?id=1194472#c2 Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com Fedora Windows cross-compiler.
