what exactly virtualisation You would like to do? Where are you looking in manuals?
Till now I heard only that Sidewinder is able to run multiple firewalls on one ESX server. But this mean that to do different routing tables, VRF, different policies You have to start another instance (virtual machine) of the Sidewinder firewall. You are not able to do VRFs, policy routing on one single firewall. Also I think 1100F is not ESX model of Sidewinder. Sidewinder is more firewall than router comparing with Cisco. Cisco instead has more router capabilities but less firewall ones than Sidewinder.
Of course it is possible that I am wrong.
