Hello Fabian,
thank you very much for your answer.

programme is really working, and

Okay, here is what I do:
- first I turned off the KSM function on the host that is going to hold my
VM
- then: onevm create vm_2GB.qemu
- then: ssh user@vm_2GB
- then: lookbusy -m 2000M

Well that's normal if not usinng balloning. The hypervisor (outside
the VM) allocates the whole memory till the VM is destroyed

What hypervisor are you using? If you are using KVM then this
behavior is normal, KVM only actually occupies the amount of RAM
that the virtual machine is actually using at the time and
OpenNebula reports the usage accordingly. this makes it possible
to overbook and put 16 2-GB KVM VM's on a
Yes, I am using KVM, indeed. But let me set this straight, the programme
lookbusy that I am using, utilizes the VMs completely (the whole 2GB) and
when I e.g. look at the memory usage inside the VM (via top, or free) it shows
that the whole 2GB are used. However, the physical machine doesn't
Okay, I found out additional infos regarding my problem. As it seems, the
fact that the libvirts ksm dynamically manages the memory pages, which
obviously leads to a stabilization of used memory, when the VMs virtual
memory is utilized to the maximum. This is why I deactivated ksm and
voila:
However, I have another problem now – after I finish the utilization of my
VM (which means, I kill the util. process, thus making all my virtual memory
free again), the real host memory still stays utilized.
Could that the memory no freed be in the cached/buffers?
What could be the reason
