Hello all!

Im playing around with arch as a server and noticed something odd. VM load averages 0,04 0,05 0,01 . Nothing major there, disk io is a couple of bytes randonly, network traffic a dozen kbits/s. So basically as the server status shows its an empty minecraft server idling. But for some reason when i opened htop in tn scale it showed that the quemu process for that vm uses 200% cpu. The arch install itself is very basic. The minimum system plus a few tools.

Never dealt with kvm/quemu so i could use a few pointers where should i start looking for the cause... :confused:

Oh for ..... sake, as much id like to use ddgo exclusively ill have to drop it :mad: . It was the minecraft server, added "nohz=off highres=off" to kernel params in grub and the problem is gone.....
