I have two nodes running identical hardware which run Xen VM's, and want to add
a third node to the cluster which can access the same clvm and iscsi resources,

move a VM to this third node it it must be stopped then started, a migration
will not work.
This situation may not really come up as in most cases I'll use location
resources to restrict VM's to only the first two nodes (third node will mostly
be for a different purpose), but just in case I want to do that for one or two
VMs, is it possible to come up with some sort of rule like:
A->B = migration allowed
B->A = migration allowed
A->C = no migration allowed
B->C = no migration allowed
create an asymmetrical cluster.
add a node property, e.g.
> node xxx attributes service="web"
create corresponding location rules, e.g.
location loc-web-fs-www web-fs-www \
rule $id="loc-web-webfs-www-rule" 100: service eq web
