Will that work with XCP if you migrate the VM to another node in the pool?
Or does that need to be set up in the dom0 of the physical node after the VM
is moved?

There is a way to limit the incoming traffic for domU in dom0 on vif with

For example:

dom0:~ # tc qdisc add dev vif1.0 root handle 1: htb default 1
dom0:~ # tc class add dev vif1.0 parent 1: classid 1:1 htb rate 5mbit
