 * Install with:

{{{
apt-get install xen-hypervisor-3.0.3-1-i386 xen-linux-system-2.6.18-4-xen-686 libc6-xen
}}}

 * Edit /boot/grub/menu.1st

{{{
## Xen hypervisor options to use with the default Xen boot option
# xenhopt=dom0_mem=131072
}}}

 * run update-grub and reboot

 * Install bridge-utils and xen-tools

{{{
aptitude install bridge-utils xen-tools
/etc/init.d/xend restart
}}}

 * Edit /etc/xen-tools/xen-tools.conf. Apply the following diffs:

 * Create new xen instances with:

{{{
xen-create-image --size=5Gb --swap=512Mb --gateway=209.51.180.17 --netmask=255.2
55.255.240 --ip=209.51.180.24 --hostname=mendes
}}}

 Change settings as needed.


==== Encrypted File system ====

 * Install programs:

{{{
$ sudo apt-get install dmsetup cryptsetup
}}}

 * Create an encrypted file system for members:

 * Now, unmount the partition (make sure there is no data on it that you care about).

{{{
$ sudo umount /home/members
}}}

 * Create the encrypted filesystem:

{{{
$ cryptsetup luksFormat /dev/mapper/vg_NAMEOFSERVER0-members
}}}

You will be prompted for a password. Put password in resource db!

 * Add to crypttab

{{{
echo crypt_members /dev/mapper/vg_NAMEOFSERVER0-members none luks >> /etc/crypttab
}}}

 * Start it

{{{
/etc/init.d/cryptdisks start
}}}

 * Create a file system on the partition:

{{{
$ mkfs -t ext3 /dev/mapper/crypt_members
}}}

 * Remove cryptdisks from the rc2.d directory - we do not want this to start automatically on boot! Instead we want to start it manually so the boot process doesn't hang waiting for a password.
