They are affected but there is no fix yet.
64-bit PV is unaffected and won't suffer a performance penalty (more precisely, it was already suffering it!!!), hence my original question, but a 64-bit PV guest can use Meltdown to attack the hypervisor. The fix is to update Xen, though I am not sure if fixes are already publicly available.
