From what I have seen, just make sure that you allocate enough RAM and processor to each VM running SQL. You should not put mor that 10-12 VMs per VMFS LUN - maybe less is there is high disk I/O on the SQL. There are best practices whitepapers that you should follow for performance, etc. Your best place to start is to do a Capacity Planner analysis of any servers you wish to make virtual. this will guide you in consolidation ratios and give you good performance stats.
You can certainly PM me if you have more questions, but you would probably be better off posting a new question in the forums. That way you will get a bunch of different opinions.
