Worse even: If the startup memory becomes to low, the VM starts swapping instead of enabling the extra memory Hyper-V has granted the VM.At some point Hyper-V always show that the Linux VM has low memory, hence it will give more RAM to the Linux VM even if tools like free, top or htop show that the VM is perfectly happy with the memory it has and that Linux doesn't see the extra memory Hyper-V.A couple of seconds after bootup is finished, dmesg shows a message from hv_balloon how much the maximum RAM size is.Note: This step takes a while to complete.I remember that Dynamic Memory was not supported with Linux in the earlier days but I decided that I might give it a go on Debian 9 (based on kernel 4.9) and the upcoming 10 (based on 4.19) on our Hyper-V hosts that are running 2012 R2.Īs of writing I don't think that the memory ballooning works as it should out of the box, and I couldn't others who have seen the following behaviour: This is a step that many online instructions missed.
