[rdo-users] [TripleO] Undercloud unreachable

Hi Ashish,

just my experiences... 16GB is not *really* enough, although if you
allocate 16GB swap it *should* install. As you're running on bare metal, if
it really complains, rather than chase it - just do a re-install. That way
you, and everyone else, knows you have a 'clean' installation. But, if the
extra RAM is due today, get the RAM in and do a re-install with 32GB swap.
The system will thank you for it by not being in the land of the "weird
errors".

Hope that helps,

Phill.
