Description of problem: The v2v logs in containers are much larger than in previous versions running on RHV Host or OSP instances. This is due to the addition of nbdkit messages to these logs. Version-Release number of selected component (if applicable): How reproducible: N/A Steps to Reproduce: 1. Run conversion 2. Check logs ;) Actual results: The log sizes are quite big: container logs: $ wc -c v2v-import-20190924T224558-14065.log 103661017 v2v-import-20190924T224558-14065.log non-container logs: $ grep -v "^nbdkit.*count=" v2v-import-20190924T224558-14065.log | wc -c 29205798 Expected results: Reduced log sizes if possible.
nbdkit-1.16.2-1.el8 contains the required changes in nbdkit. This still requires a single line patch to virt-v2v. See also: https://bugzilla.redhat.com/show_bug.cgi?id=1756307#c3
There's a rather complex fix for this upstream now in https://github.com/libguestfs/virt-v2v/commit/74a69a181bf2e4b26c2c15c5c33851d8f5cb4cfa To get the full fix also needs further changes to nbdkit (>= 1.17.10). This isn't really going to be possible to backport for RHEL AV 8.2. It will have to wait until virt-v2v is rebased as a new package in AV 8.3, and the full effect will not be clear until we also rebase nbdkit. Note ITR = 8.3.
This was fixed/implemented in virt-v2v 1.42.0, which was introduced in RHEL AV 8.3.0.
