Description Kyle 2015-10-02 05:27:49 UTC

Description of problem:
copr builds are building successfully, but the final rsync fails with an error message.

Version-Release number of selected component (if applicable):


How reproducible:
Random, occurred twice on Fedora Rawhide, once on EPEL 7, but I only did 5 builds.

Steps to Reproduce:
1. Start a copr build, possibly only on EPEL7/Fedora Rawhide
2. Wait
3. Build might be marked as failed despite rpm packages being in the fold afterwards.

Actual results:
Some copr builds fail inexplicably in the middle of an rsync job.

Expected results:
Rsync is successful

Comment 1 Miroslav Suchý 2015-10-05 10:38:19 UTC

This seems to be cause by some issues in libvirt network card driver.
I followed
  https://www.rdoproject.org/Using_GRE_tenant_networks#Offloading
and disabled offloading on frontend, backend and builders.
Hopefully (as I can not reproduce it deterministic) it resolve this issue.

If you ever hit it again, please reopen this BZ.
