VMWare ESX Server, by default, does not allow outgoing SSH connections.
You must be very careful where you place your memory. On a dual proc HP 385, as an example, you have two processors and 8 slots for memory. Each processor must have access to the same size of memory. For example, proc A has slots 1 & 2 full of 1GB DIMMs, then proc B must have slots 5 & 6 with 1GB DIMMs. You will pull a lot of hair with the errors you’ll see if you make this mistake.
