All domUs have disks on LVM, disks are located on a SAN, so it is very easy to live migrate simply by attaching a domU disk on two dom0s.All dom0s run CentOS50 with Xen 3.0.3.We tried many time to migrate in vitro some little domUs and it worked perfectly.Now we really need to migrate a big domU (big by its RAM: 3.6 GB) and we have the following error (log on the from dom0): Your problem is probably that live migration requires Xen to create a shadow copy of the active RAM of your DomU, so you effectively need to have RAM(DomU) free on the source and 2*RAM(DomU) on the target Dom0.
