| - To do a live migration for a domU, the back-storage of your virtual machine must be shared storage, like iSCSI , AoE, etc... Setting up AoE is explained at ata-over-ethernet and iSCSI at configure-iscsi-target-linux. To do live migration between two host, these hosts must be on the same subnet, layer 2 network. To make it as easy as possible on each host : First, be sure to properly install Xen on your system, and set up some options, Install_xen_debian. In this example it is assumed that there is already a vm running on host_1. So, here are the steps to do live migration.

| - To do a live migration for a domU, the back-storage of your virtual machine must be shared storage, like iSCSI , AoE, etc... Setting up AoE is explained at ata-over-ethernet and iSCSI at configure-iscsi-target-linux. To do live migration between two host, these hosts must be on the same subnet, layer 2 network. To make it as easy as possible on each host :
* host_1 : the host the vm is running on before migration
* host_2 : the host the vm is running on after migration
* storage_host : is the host running the storage area, it doesn't known anything about xen or live migration, it only has data.
* guest :the virtual machine to migrate from host_1 to host_2 Here the xen vm is shared on an iSCSI device. The procedure to do it on a AoE device, will be very similar. In the sample configuration there are three hosts, between host_1 and host_2 we will perform live migration, and the third host runs the iSCSI storage area. First, be sure to properly install Xen on your system, and set up some options, Install_xen_debian. In this example it is assumed that there is already a vm running on host_1. So, here are the steps to do live migration.
