You might want to try out SmartOS: one .json file, vmadm(1M) and imgadm(1M) commands later, you'll have a fully isolated UNIX server, running at the speed of bare metal and residing on ZFS, protecting your data. If you need a more complex network setup, dladm(1M) will enable you to configure virtual switches and routers. The manual pages are really good, too. And there is nothing to install, as SmartOS runs from memory, so that all storage in the system can be used for virtual servers. Upgrades are a breeze by just booting into a new image, either from USB or PXE booting from the network.
