similar to: [PATCH 00/18] rvh-upload: Various fixes and cleanups

This series extract oVirt SDK and imageio code to make it eaiser to follow the code and improve error handing in open() and close(). Tested with virt-v2v master. Changes since v1: - Rebase on merged patches from v1 - Fix regression introduced by "rhv-upload: Fix cleanup after errors" - Remove "rhv-upload: Try to remove disk on timeout" since it cannot succeed - Add more

v1 was here: https://www.redhat.com/archives/libguestfs/2018-June/msg00099.html v2: - Just fixes the two problems noted in the review of the previous version. Rich.

These two patches add support for using a Unix domain socket to directly access imageio in the case where imageio is running on the conversion host (usually that means virt-v2v is running on the RHV node and something else -- eg. CFME scripts -- arranges that the RHV node is the same one running imageio). Conversions in the normal case are not affected - they happen over TCP as usual. This was

v7 was here: https://www.redhat.com/archives/libguestfs/2018-March/msg00143.html Since then: - Earlier patches are now upstream. - The to-do list is moved from the commit message to the TODO file. - This version forces -of raw + -oa sparse and gives an error in any other mode. We intend to lift these restrictions later. - Tested against latest imageio which supports longer timeouts,

v8 was here: https://www.redhat.com/archives/libguestfs/2018-April/msg00022.html v8 -> v9: - Addresses the only feedback from Tomáš. Rich.

Fix NameError introduced by inocomplete change to extract create_transfer() by extracting cancel_transfer() function. Finally extract finallize_transfer() function, dealing with the poorly documented and over complicated oVirt SDK. Tested with: libguestfs-1.40.2-4.fc30.x86_64 nbdkit-1.12.8-1.fc30.x86_64 Tested flows: - Successful import - Error in close() - by injecting long sleep in vdsm

v5 was here: https://www.redhat.com/archives/libguestfs/2018-March/msg00032.html There is only a single patch in this version because the other patches went upstream. This patch adds the virt-v2v -o rhv-upload mode (https://bugzilla.redhat.com/show_bug.cgi?id=1557273). Compared to v5, this adds the ability to make zero, trim and flush requests to the oVirt imageio server

v2 was here: https://www.redhat.com/archives/libguestfs/2018-June/msg00109.html v3: - Added/fixed all suggestions from Nir in previous review. Q: I wasn't sure if we still need the "UnsupportedError" class so I left it in. Q: Does the Unix socket always have the same name? What happens if there's more than one transfer happening? I tested this both ways, and it worked both

Previous versions: v3: https://www.redhat.com/archives/libguestfs/2018-March/msg00000.html v2: https://www.redhat.com/archives/libguestfs/2018-February/msg00177.html v1: https://www.redhat.com/archives/libguestfs/2018-February/msg00139.html This completely rethinks the approach taken by the previous patches. Instead of trying to involve qemu's curl driver, this uses a small Python 3

Mainly minor fixes and code cleanups over the v4 patch. There are still several problems with this patch, but it is in a reviewable state, especially the Python code. Rich.

Fixes the majority of the pycodestyle issues in the Python scripts, and fix the existing test-v2v-python-syntax.sh to use pycodestyle to actually perform style checks. Pino Toscano (6): PEP 8: adapt whitespaces in lines PEP 8: move imports at the top PEP 8: adapt empty lines tests: find all the Python scripts for syntax checks -o rhv-upload: remove unused Python imports Revamp check

Old imageio proxy was using Authorization header for GET and PUT requests. Remove unneeded authorization when sending OPTIONS request. Remove unneeded duplicated comments about authorization for old imageio, and replace them with a comment when we set needs_auth. --- v2v/rhv-upload-plugin.py | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-) diff --git a/v2v/rhv-upload-plugin.py

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.

In block storage, qcow2 image is always on a thin provisioned disk, which in oVirt is a

v6 was here: https://www.redhat.com/archives/libguestfs/2018-March/msg00126.html This makes a number of significant changes: - Input and output options now use a uniform set of -io and -oo parameters. - For -o rhv-upload, we use ‘-oo rhv-cafile=/tmp/ca.pem’ etc. The ‘--rhv*’ options have been dropped. - Rearranges the documentation. - As before includes (untested) support for zero,

The first four patches are straightforward. The final patch adds the -o rhv-upload output mode. It is still spooling into a temporary file because I've had some trouble getting streaming conversions working. There are other problems as outlined in the commit message, so this patch is not ready for upstream but is good for discussion. Also I hit this, which I'm assuming for now will be

v2 -> v3: - Lots of code cleanups. - Documentation. However this is still spooling the file into a temporary before the upload. It turns out that fixing this is going to require a small change to qemu. Rich.
