Remember that virt-v2v works by streaming. At the point where we are calling this API virt-v2v only knows the virtual size. We never know the size of the final qcow2 file. > sparse=disk_format...

v1 was here: https://www.redhat.com/archives/libguestfs/2018-September/msg00121.html v2: - Rewrote patch 2 from scratch so it incorporates Nir's suggestions. - Add fake module to EXTRA_DIST. - Retested. Unfortunately I am no longer able to test the ordinary conversion path because ovirtsdk4 is incompatible with Fedora 29 / Python 3.7:

Add support for qcow2 disk format, enabled by imageio NBD backend in RHV 4.3. To use this feature manually, you can run virt-v2v with "-of qcow2". Here is example run: Source disk: $ qemu-img info /var/tmp/fedora-30.img image: /var/tmp/fedora-30.img file format: raw virtual size: 6 GiB (6442450944 bytes) disk size: 1.15 GiB virt-v2v: $ ./run virt-v2v \ -v \ -i disk

This adds a test of -o rhv-upload. Obviously for an upstream test we cannot require a working oVirt server. This test works by faking the ovirtsdk4 Python module, setting PYTHONPATH so that the fake module is picked up instead of the real module (if installed). However it's more complex than that because the nbdkit plugin also expects to talk to a working imageio HTTPS server. Therefore

This series extract oVirt SDK and imageio code to make it eaiser to follow the code and improve error handing in open() and close(). The first small patches can be consider as fixes for downstream. Tested based on libguestfs v1.41.5, since I had trouble building virt-v2v and libguestfs from master. Nir Soffer (18): rhv-upload: Remove unused exception class rhv-upload: Check status more

This patch set is still for discussion only. See 3/3 for the current list of problems. However this will upload an image to an oVirt or RHV server, although you must have absolutely the latest snapshot version of 4.2 for it to work. Rich.
