I can set the node which seems to pin the VM to all CPU cores associated
with that node on transfer but is there any way pin the VM to a
particular core on transfer? 

Some AMD docs from early 2008 suggested this was a current limitation
but has it been fixed or patched since? (Running Xen 3.3.1 Final at the
moment)

Thanks,

Rob
