Yes. I think might also need to chmod 600 /swapfile. I do this on all my VPS, especially helps for small VPS with only 1GB ram: fallocate -l 1G /swapfile

Works really well with no problems that I've seen. Really helps give a bit more of a buffer before applications get killed. Like others have said, with SSD the performance hit isn't too bad.

Openvz and other kernel paravirtualization have limits, go for Xen or KVM instead (Xen has paravirtualization as well, but I'm not sure how much it's actually used). Full virtualization (implemented by Xen and KVM) do not allow you to prevent swap from being used.
- collinmanderson 1y agoI forgot to mention what the parent comment said, yes, need to put something like this in /etc/fstab: /swapfile swap swap sw 0 0 or via ansible: mount: src: "/swapfile" name: "swap" fstype: "swap" opts: "sw" passno: "0" dump: "0" state: present
