+===== VM Live Migration =====
+  * Live migration is a free feature
   * No need for an additional purchase
-  * The disk file of the VM has to be on shared storage
+  * Virtual disk of the VM being migrated has to be on shared storage
   * You must have installed the Xen Tools package in the VM

+:!: In the following commands, it is **necessary to configure SSH keys** for password-less access (one direction) prior.
+Using these commands, VMs are transferred (actually, exported and imported) directly from one 'source pool' member, over a secure SSH connection using the Management network, to a 'destination pool' member.
+This process will **monopolize Management network bandwidth** for a good long while, affecting/affected by all other Management network traffic for the duration of the transfers.
+Exporting, then importing will **flatten (coalesce) all VHD chains** in the process...a wonderful thing.
+==== Transfer a VM from One Pool to Another ====
+:!: VMs must be **shut down** before transferring with these commands.
+:!: Add ''sr-uuid=<desired-sr-uuid>'' to ''vm-import'' to specify the **destination SR**.  Alternately, just set the desired destination SR as the pool Default SR using XenCenter.
+CLI example, as ''root'' at the 'sender' console:
+<file>
+xe vm-export uuid=<vm-uuid> filename= | ssh root@<ip-of-new-server> xe vm-import filename=/dev/stdin
+</file>
+==== Transfer Two VMs from One Pool to Another ====
+<file>
+xe vm-export uuid=<vm-uuid> filename= | ssh root@<ip-of-new-server> xe vm-import filename=/dev/stdin && xe vm-export uuid=<vm-uuid> filename= | ssh root@<ip-of-new-server> xe vm-import filename=/dev/stdin
+</file>
+==== Transfer a Template and a VM from One Pool to Another ====
+<file>
+xe template-export template-uuid=<template-uuid> filename= | ssh root@<ip-of-new-server> xe vm-import filename=/dev/stdin && xe vm-export uuid=<vm-uuid> filename= | ssh root@<ip-of-new-server> xe vm-import filename=/dev/stdin
+</file>
+===== Export/Import to/from Mounted Storage =====
+<file>
+xe vm-export vm="Name of VM" filename="/mount/point/Name Of VM.xva"
+xe vm-import filename="/mount/point/Name Of VM.ova" sr-uuid=<UUID of storage repository to place import> host-username=root host-password=>password of xenserver>
+</file>
