===Swap Space===
Have you ever wanted to change the amount of swap space on your VM ? Here's how to ! 

==disable existing swap==
%%
# free -k
# swapoff -a
# free -k
%%

==get some more disk space==
Either repartition an existing disk or add a new disk to your GNU/Linux machine or VM
and use fdisk to create/repartition a swap partition (type 82) for your swap space 
%%
# fdisk /dev/mydisk
%%
verify
%%
# fdisk -l /dev/mydisk

Disk /dev/mydisk: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/mypart1            1         261   2096451   82  Linux swap / Solaris
%%

==make a swap partition and use a speciail swap disk label !==
%%
# mkswap -L myswap /dev/mypart1
%%

==add to fstab==
Add swap partition to fstab using your special swap disk label !
%%
# vi /etc/fstab
LABEL=myswap         swap                    swap    defaults        0 0
%%

== reenable swap ==
%%
# swapon -a
# free -k
%%

== reboot (optional) ==
Finally reboot to check new swap area gets picked up on reboot !
%%
# reboot
%%

and login and check new swap space is available
%%
# free -k
%%
