1 and 3 are essentially the same arent they?

2. Install new servers, add them to the cluster, install SQL. Failover to the new nodes, shutdown the old machines.This method sounds good, but has it ever been tested with the combination of physical and virtual machines?
Between physical only machines it should work.
Pro: Fast, minimum downtime, Roolback plan available.RollbackFeels risky, due to diskmappings. (Wmware on this lvl isn't VMWarerd).
Clustering a physical and a virtual machine is quite common and works well when done properly.
I wouldn't be in too much of a rush to just dump the virtual infrastructure just yet. Can you provide a little more info on the system setup?
