To enable swap on a system that has no dedicated swap partition (such as a really small VPS or VM), create a swap file:
# dd if=/dev/zero of=/swap bs=1M count=1024
# chmod 600 /swap
# mkswap /swap
# swapon /swap
# echo "/swap swap swap defaults 0 0" >> /etc/fstab
Naturally, the swap space here incurs the filesystem overhead as well.
