-====== Xen Server dom0 ======
-You should create a partition a bit larger than the amount of ram allocated to domU guests.  If you shutdown the dom0, the domU guests are saved state to '/var/lib/xen/save'
-<code>
-lvcreate --size 4.1g --name xen vg01
-mkdir /var/lib/xen
-</code>
-And add to /etc/fstab
-<code>
-/dev/mapper/vg01-xen /var/lib/xen            reiserfs noatime         0       2
-</code>
-and mount
-<code>
-mount /var/lib/xen
-</code>
-====== Xen Client domU using debootstrap ======
-Below 'vm01' is the hostname of my VirtualMachine.  The Xen host has 2 Raid 1 mirrors, so I want to stripe across them creating a Raid 10.

-Start the installer:
-<code>
-xm create -c ubuntu14.cfg
-</code>
-After the install, revise the cfg file to comment out the local kernel/ramdisk and add pygrub.
-<code>
