I have a refurbished Dell PowerEdge 1800 with 12 GB of memory and three RAID-1 arrays.  I have Windows Server 2008 Enterprise (32-bit) installed.  I want to use this machine to host four or five virtual Windows 7 (32-bit) machines.  From what I can surmise, the PowerEdge 1800 processor does not support Hyper-V, so I cannot use Hyper-V to accomplish my objective.  What can I use as an alternative to meet my objective?  My hope is that whatever solution I choose will be at least as easy as the Hyper-V manager, will run on my host (not require another workstation to manage the virtuals), and will be relatively inexpensive.  Thanks for any help.
