At least systemd would load blktap2 and blktap via xen.conf. And the
SUSE xencommons also loads both drivers. So I think they can coexist.
No sure what the intent of the initial "modprobe blktap2 || modprobe
blktap" was. I think doing it that way did not solve a real bug. The
comments in the discussion at that time did not provide a hint that a
bug was fixed.
