I think that you can leave the Hosted Engine VM with 4GB of ram (minimum
requirements) which will be added to the 2.5GB of RAM you're already using.
So you'll have something like ~9 GB of RAM using it 1:1.

With hosted-engine, the engine runs in its own VM. If you allocate to
this VM 4GB, you get Sandro's calculation.

Hello Sandro,

iam not sure if we talk about the same, since iam new with ovirt. But i 
have installed self-hosted-egine, where i cant change the amont of 
memory for the engine-vm, since its the same host. am i right with this? 
so what is the calculation for this?

thx

[ovirt-users] Calculating Requirements

[Taste-Of-IT]

Hello,

i have a testsystem with 16GB RAM and ovirt as sef-hosted-engine on 
centos7. i have no vm started and the host consume 2,5GB RAM. In 
documents it is written that the engine needs aprox 3GB RAM and the 
system self 1GB RAM. At all nearly 4GB RAM. So i can use aprox 12GB RAM 
for virtual machines if i use the ram 1:1. is that a good point of 
calculation, or are there any other points to calculate?


thx
