Re: [ovirt-users] Memory hot plug
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).

No, you're not. Now the vm is seeing the base memory (4GB) you were
seeing at boot, plus additional memory (2GB added). Next time you'll
boot the vm, the system will see a single block of 6 GB.
That's the difference.
