CHR Total Memory

Fri Aug 20, 2021 6:24 pm

Hello,

I have CHR installed from OVA template (https://mikrotik.com/download)
vSphere Client show VM Memory: 128 MB
but Winbox show System - Resources - Total Memory: 96 MB
why is there less memory?

I was able to reproduce it on Hyper-V and VMware
The Linux kernel running under the hood is probably the reason why!

The hypervisor will also reserve some memory for video RAM.

On download page are present 4 version of CHR OVA...
Is nice than the OP have not specified what version have used for test...

If you want 128MB of virtual memory, set the total memory to 132MB
On VMware you can set the memory with 4MB step,
but on that MikroTik Linux Kernel (3.x) the memory must be a multiple of 32MB,
if you remove 4MB for video memory (128 - 4) remain only 124MB and the closest multiple of 32MB are 96MB (32 x 3)

You now have the solution, dear noob mikriter,
I mess up your thread with my solution. First, learn how VMware, and the Kernel used from RouterOS, works.
