This is important to remember. The virtual machines are all sharing the
same CPU, memory bandwidth, network bandwidth, disk bandwidth, etc of
the actual machine.
The actual OS of the machine is also going to take a share of machines
resources. If more than one of the VMs is likely to make intensive use
of the same resource then things can come unstuck. As well it being
quite possible that a single machine powerful enough would be more
expensive than 3 machines speced appropriatly.
