Swap memory not coming on in Xen VPS

Sometimes swap memory is not detected when a Xen VPS starts, and can be fixed by doing the following.

After logging into the VDS, check the entries in /etc/fstab/. If swap entry is there, then use the command “swapon -a” and then use the “mount -a” command.

If swap entry is not present in /etc/fstab, add that first.
==================
/dev/sda2 swap swap defaults 0 0
==================

After that, apply the above commands.
