Subject: [ovirt-users] 3.5.1 not detecting Haswell CPU
Hi,
I just upgraded from a working 3.5.0 on F20 to 3.5.1. After the
upgrade, 3.5.1 started detecting my i7-4790k as a Sandy Bridge, and not
the Haswell it properly detected with 3.5.0. I had to force the CPU
type to Sandy Bridge in order to bring the node up.

I have vague memories of similar bugs in the past. Can you please share
the libvirt debug logs of one hypervisor host which has this misbehaviour?
