I'm actually more concerned about the CPU utilization on the box than anything else.. 35%-50% of 2x dual-core isn't something I'd necessarily say is a big deal in a virtualized world, but with Novell, the rules aren't the same as with Windows and Linux. Keep in mind that any Novell VM's you setup will only be capable of having 1 vCPU. There's no way to change this to 2 vCPU's in any release of ESX I know of... and I just checked both to make sure that didn't change in 3.5, and it hasn't... The network numbers are high, but doable, but I'd be worried you're going to be pegging a single vCPU and causing performance degradation for users.
