I have prepared a basic CentOS 5.4 Virtual Machine for users who may wish to run NMIS in a virtualized environment.
The VM is CentOS 5.4 Server only, commandline access ( No GUI).
A working copy of NMIS 4.3.6f has been pre-installed and tested.
It will run from boot, polling localhost.

Due to the size of the VM Appliance file, I have hosted the VM binary at S3 Amazon.
