A high watermark of over 5 minutes is pretty long for a test.

Looking at the test I see it runs

   self.ssh_command('dnf -y install numactl-devel')

but then never actually uses the installed package.

I expect that most of the wallclock time here is coming from having
dnf download all the repodata, 4 times over.

If the intention was to test networking, then replace this with
something that doesn't have to download 100's of MB of data, then
see what kind of running time we get before increasing any timeout.
