[Users] Difference between swap and swappages?

[Arjit Chaudhary]

Hi,
Aha so they're the same thing, was just curious as I've been noticing a bit
of odd behavior on OpenVZ 7 host-nodes where the node has 128G RAM, around
30G used and it's swapping out 12G still instead of using the RAM as vSwap.
Swappiness is set to 10 as well.

I'm using the following commands to build the container if that help,

/usr/sbin/vzctl create $VMID --ostemplate $DISTRO
/usr/sbin/vzctl set $VMID --ipadd $VPS_IP --save
/usr/sbin/vzctl set $VMID --hostname vps.server.com --save
/usr/sbin/vzctl set $VMID --nameserver 8.8.8.8 --save
/usr/sbin/vzctl set $VMID --diskspace
$DISK_SPACE$DISK_VARIABLE:$DISK_SPACE$DISK_VARIABLE --save
/usr/sbin/vzctl set $VMID --ram $RAM$RAM_VARIABLE --swappages
$SWAP$SWAP_VARIABLE --save
