Make a VM small like sys-net

[83048930]

I made 2 network kinda VMs one sys-vpn, and one sys-whonix-vpn which uses the VPN VM.
Now they are using each 3984MB ram. How can I make them as thin and small as sys-net oder usb-net with just 384mb?
I used this tutorial to setup the VPM VM for example, just basic fedora template.

That’s how memory balancing is working in Xen, it’ll give the VM maximum memory available and can reduce the memory later if it’ll be needed by other qubes and no more free memory will be available:

Why is the RAM always gone?

Not sure about increased CPU load but the memory increase you described looks like Xen memory ballooning: For example, if the Dynamic Minimum Memory was set at 512 MB and the Dynamic Maximum Memory was set at 1024 MB, this would give the VM a Dynamic Memory Range (DMR) of 512 - 1024 MB, within which it would operate. With DMC, XenServer guarantees at all times to assign each VM memory within its specified DMR. When the host server’s memory is plentiful, all running VMs will receive their Dyna…

You can disable the memory balancing if you don’t need it and the qube will only be assigned with minimal memory.

You can also reduce the memory allocations to the new qubes: sys-net has
memory ballooning disabled, and only 400M allocated.
If you think you are getting issues with memory allocation then you can
reduce the maxmem setting for qubes to less than the default: qvm-prefs QUBE maxmem.. Otherwise, leave it alone, and dont worry about it.

I never presume to speak for the Qubes team. When I comment in the Forum I speak for myself.

How do i turn off memory ballooning?

Qube Settings → Advanced tab → uncheck “Include in memory balancing”
