..... works like a charm until it doesn't.   Any PV based STP will not  
work in a dense server virtualisation environment.  So these days  
that's basically any hosting provider.  MST is your only choice and if  
you pre-provision your vlan/instance mappings it works fine.  Been  
running it without a single issue for ages.
