What virtualization software (hypervisor) are you using? VMWare, VirtualBox, KVM, Xen?

How did you set up the NIC in the hypervisor? NAT vs bridged vs host-only?

In Virtualbox I set up two NICs, one as NAT and one as host-only in order to make my VM available to other VMs, the host, and enable access to the outside world while still protecting it from the host's physical network.
