When I wrote [1], it worked for me.
If something does not work for you, I think it's best to open a bug
and attach all relevant logs, including hosted-engine-setup and vdsm
logs from the host and all engine logs from the engine vm.
I can't tell from your log snippet why your new host failed to attach
to the storage domain. If it's reproducible, please check/post vdsm logs.

Even if there is another option, the fact that you can't add a host
is probably problematic in itself, no? What if you actually need to
add a host?
Did you try adding a el6 host and it did work?
Best,
