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

I haven't had much luck with storage live migration yet.

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.

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:

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 && xe vm-export uuid=<vm-uuid> filename= | ssh root@<ip-of-new-server> xe vm-import filename=/dev/stdin

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

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>
