Yes, I do.  Gold crown indeed.

It's the "HostedEngine" as seen attached!

Hi Simone

Can I get help with this issue?  Still cannot increase memory for Hosted Engine.

From the logs it seams that the engine is trying to hotplug memory to the engine VM which is something it should not happen.

The engine should simply update engine VM configuration in the OVF_STORE and require a reboot of the engine VM.

Quick question, in the VM panel do you see a gold crown symbol on the Engine VM?

Sure, they're attached.  In "first attempt" the error seems to be:

In "second attempt" I used values that are dividable by 256 MiB so that's no longer present.  Though same error:

As you can see attached the host has plenty of memory.

Sorry for accidental send.

Anyway I try to increase physical memory however it won't go above 4096MB.  The hypervisor has 64GB.  

Do I need to modify this value with Hosted Engine offline?

No, it's not required.

Can you please attach your engine.log for the relevant time frame?
