[Xen-users] Xen live migration dom0 memory


I'm new to XEN live migration. I have a question regarding XEN memory management while doing a vm live migration. I observed that migrating a vm on XEN 4.5.1 and Linux Kernel 4.1.0 requires the dom0 on the target machine to have memory available that is the size of the memory allocated to the vm (2G). Since I follow "XEN best practices" and set dom0_mem to 512M the target machine begins swapping out 2G to disk which makes everything nearly unresponsive. Is this requirement for the dom0 memory size intended or might there be an issue with my setup?
