excessive use of ram in vm ubuntu 18.04

[ONE FOTON]

Hi everyone!
is this normal?

it is only on ubuntu is not running anything
is there any special setup that needs to be done on a linux kvm guest?

orientation, all orientation will be well received!
regards

Hi!

I mean, it can be normal, I have an ubuntu 18.04 with GNOME desktop not running really any program hovering a 4 GiB of 6 GiB available.. If you also have a desktop environment in the VM that could be the cause.

What's the VM's memory usage from inside the VM?
Check the free -h command in the VMs console/terminal.

If that's also high you could look for the processes actually using a lot of memory with:
top -b -E m -o +%MEM | head -15

Albeit, the biggest chunk of that memory is used by the page cache - which is a buffer to make filesystem much faster by using memory not used by any other process, the free -h command will show you that (buff/cache column)

the problem is in kvm hardware virtualization

if I don't enable it, I don't get overloaded by the guest ram.
but if the CPU overloads me!

that you need more memory with KVM enabled makes no sense..

Start to post the info I requested, you give the VM 4GiB it can use up to 4GiB, it's as simple as that.

well here are the required data


how can the use be improved a lot ... after several fixes.
1- add more ram
2-modify various aspects of the hardware

3-in the guest install
open-vm-tools, open-vm-tools-desktop, cloud-guest-utils, qemu-guest-agent.
Here I would appreciate your opinion because I think there are several packages that are not necessary, so!
4-and finally the options
