Just to chime in here, trying a fresh hosted engine deploy today on AMD EPYC servers, the exact same error kills the deploy. So it's not you or your CPUs/servers, there's a bug in the Ansible routine that was introduced with 4.4.2 that makes hosted engine deployment impossible. I was able to deploy hosted engine on these servers using 4.4.1 without issue but hit a different (non-oVirt, rather Linux kernel) issue. As I was given a test kernel to work around that, I wanted to try deployment again so I paved the server, completely fresh install of CentOS 8.2 w/ all updates then added the kernel that fixes the bonding/bridge issue. The hosted engine deploy will reliably fail every time on that step with that error, this is a regression with 4.4.2. Regards, Mark
