Hi, I'm trying to prevent a qemu process from using swap and noticed that in addition to /proc/sys/vm/swappiness systemd and cgroups now play a role in this.
I set /proc/sys/vm/swappiness to 0 and did the same for /sys/fs/cgroup/memory/machine.slice/memory.swappiness and /sys/fs/cgroup/memory/machine.slice/<qemu-process>/memory.swappiness yet when i look at look at the VmSwap values for the process it still goes up sometimes indicating that more swap space is used: [root@virt7 machine.slice]# cat /proc/31655/status|grep VmSwap VmSwap: 3725508 kB I noticed that some values can be set using "systemctl set-property" but memory.swappiness does not seem to be among them so i used "echo 0 > ..." to set the above values. Is there something else that needs to be done to apply these values to the running process?
