Description of problem:

systemctl start ovsdb-server gives a ton of kernel warnings. In digging in a bit, I was very surprised to discover that ovs uses the `perf_event_open` system call, from `perf trace`:

2873.260 (13.631 ms): ovsdb-server/2354 perf_event_open(attr_uptr: 0x7ffd1c915ab0, cpu: -1, group_fd: -1) = 16

Traces look like this:
