BoxGrinder is a set of projects that help you grind out appliances for multiple virtualization and Cloud providers.
Although VMware Server 2 should be able to support 64 bit guests it needs to be installed ontop of a 64 bit OS on a 64 bit CPU which has VT support.
For example a Dell PowerEdge 1800 with Intel(R) Xeon(TM) CPU 3.00GHz can only run 32 bit guests ! and if you try to install or run a 64 bit guest you’ll get the error message:
Message on www: This host does not support VT.You have configured this virtual machine to use a 64-bit guest operating system.However, this host is not capable of running 64-bit virtual machinesor this virtual machine has 64-bit support disabled.For more detailed information, see http://vmware.com/info?id=152
