Open Stack

Hi Tony,

Check your docker version, IIRC v20.10 removed the kernel memory option, so
you may need to downgrade docker on the new nodes. Alternatively you could
update kolla-ansible to a newer version where this check isn't used, we
came across this when upgrading to wallaby and past it.

Cheers
Michael
