Yes, this seems like a case where virtualisation is a good solution. 
I've only just started learning to run Xen myself, but the advantages of 
virtualisation over dual/triple booting etc are pretty clear. As well as 
the ones you mention, different machines can also be run concurrently 
and networked.
