IMHO we don't have flags to require this. I guess KVM hosts nowadays should have
more than 2 threads (these tests are for bare metal), thus we don't have to note
this also in the code, right?
Anyway LGTM.
Reviewed-by: Petr Vorel <pvorel@suse.cz>
Waiting some time if Cyril, or somebody else will have time to look into this
change before merging whole patchset.
NOTE: whoever will merge this, it requires to change second commit:

Kind regards,
Petr
