Good point. Virtualization has many benefits: easy migration, lab testing, flexible in hardware resource, not so dependent on hardware-ageMy mayor gripe with virtualization is the licensing model some software vendors use. If you have more than x cores than you need our super expensive license.
If you buy a modern cpu with 6 cores you need to pay license fee for all of then, doesn't matter if the virtual machine with the software on only uses 2. If you run it in a failovercluster you have to pay twice(2*6) as the cluster is viewed as one whole.
A minor is the added complexity of resource usage/influence tracking.
if your main issue with vm is licensing, you are in for an interesting year. My primary issue with vm'ing SQL Server is that no matter how many cores you pay for its a waste of money on vm.
