I am under the impression that 2 of the 6 GB on a ESXi 5 host are not used.
This is a single host with a free licence.
When I assign resources to the VMs there is only 4GB available, and under "resource alloction" in the vSpehere GuI client there is only 3736 MB total capacity RAM dispalayd.
But in configuration - memory I can see correctly the 6 GB RAM.
At first the Host had only 4 GB and I upgrade to 6 later.
I tried to enter more here in the yellow box as suggested, but an error message shows the upper limit
EDIT: Now this is solved, I try to explain what was the mistake:
- It is possible to use all the amount. For example I can create another VM and it will have all the not yet reserved memory avalable for reservation
- The sum of 6GB can be divided into several reservations. If a part is reserverd, in the next reservation only th remainder is shown as availble, and not the total amount. If 2 GB of 6GB total are reservdr, it will show 4GB available for another reservation.
EDIT: Later I understood why: When in the other resource pool there is 2GB reservered, obviously only remaining 4GB can be entered here to reserve.
Here you can see that it shows 6 GB total:
"Resource allocation" has also only 4GB total
EDIT: now after solving the issues, this is what remains unsolved, hot to interpret the memory "Toatal capacity" and "available capacity" and why is there sometimes not shown all the capacity? but after creating an additional vm with more ram, these values also increased, so no need to worry anymore.
I can see 6GB in the host summary:
