My last detailed response still applies however I'm assuming it wasn't clear. Your problem is a Capacity Planning problem. What you need to figure out is what types of workloads you'll have in the VM's as well as the type of O/S you plan on installing. For example, you may have the following break down: o 5 VM's running Linux e-mail servers o 7 VM's running Windows 7, user's surfing and checking e-mail o etc Next, for each group, you need to determine how many resources are needed at /peak/ period. Suppose the e-mail servers typically handle 100 e-mails per hour (super light) but at 2 am, they all get backed up. The back-up would be a peak period for both CPU and IO. Once you have peak values per group, you sum those values to size the Host O/S to ensure the Host O/S can accommodate the VM needs /plus/ its needs - don't forget the Host O/S. I hope the above is clear. As I said, your issue is a Capacity Planning problem. You need to know the expected /peak/ demand. You and/or your customers should know both the expected /peak/ demand. Now, if it were /me/, I'd set up a VM of each type and install the customer software and emulate their workload while monitoring the Host O/S. This would give me hard numbers from which to plan on the Host O/S. I'd add some extra `fluff' for growth. Ah yes, don't forget expected growth in your sizing.
