  It's KVM (you see it on vda as device) and it's hostbill as panel.

  The question is about is it worth it to be worrying. I do not have any real issues with it, beside that it's strange to see how the RAM goes down each time I login to Virtualmin.

  Probably will send them a ticket, hear what they says. Have a feeling that they might increase the price, force me over to a new plan, or their new service.

  It's interesting what will happen if you actually start using RAM, i.e. will it start increasing again.

  Use Memtest86+ or Memtester.

  The command memtester 20000 1 will allocate 20GiB of RAM.

  as he said java, simplest way run a minecraft server and allocate 95% from your free memory.
  When you get a memory error, memory is overzold for sure.

  I don't think there's any good reason to purposely waste ram. Do you see vballoon in ps aux?

  Yes

  root 679 0.0 0.0 0 0 ? S 12:39 0:01 [vballoon]

  So they are overselling their KVM product? Was sure that only was a problem for OpenVZ.

  OpenVZ, Xen & KVM all can be oversold. It's harder to oversell certain things but not impossible.

  Add the following line to /etc/modprobe.d/blacklist.conf

  blacklist virtio_balloon

  Then reboot and do free -m.

  You are a genius. That worked very well:

  free -m total used free shared buffers cached Mem: 2128 310 1818 0 23 76 -/+ buffers/cache: 209 1918 Swap: 2271 0 2271

  Real memory 2.08 GB total, 281.05 MB used

  Naturally it's possible, it's your ram and you should be able to do as you please, I just said there wasn't a good reason.
