Thanks for your reply! You are right. I tried with a CentOS 6 and a CentOS 7 guest and both picked the extra memory with no problem.
Seems it was a particular issue with the guest that I tried first. Kernel version was older and I had to activate the memory bank as described in https://kb.vmware.com/s/article/1012764 (different hypervisor, but the principle is the same).
