I have run nessus 3 on real hardware and in vmware instances. In my experience although nessus will run on vmware it will not perform nearly as well in vmware as on real hardware.
The biggest performance factor I am aware of is memory. Make sure there is enough to support the scans you are doing. How much memory you need depends entirely on your scan configuration, there is no one size fits all. If performance lags consider allocating more memory or adjusting the scans so that less memory is needed. If you are running constant scans there's a breaking point for any configuration and environment: in mine I need in excess of 1.6GB RAM to avoid going into a performance quagmire. Less memory than that and the load will gradually build until nessus (and the entire system) is effectively brought to a halt. Again, the point depends entirely on environment and configuration.

The base OS is Suse 10.1 running VMware server. I have created a Backtrack 2.0 virtual machine and loaded nessus 3.0.4. Is anyone on this list running nessus in a virtual machine? I ask because when nessusd loads it gives a warning message saying performance is abysmal running in vmware. Will this work or not? __________________________________________________ Do You Yahoo!?
