(can people please correct me if I am wrong, or misleading....) a) Linux boots up on a kernel (say 2.6, can be any linux kernel with Linux-VServer patches) into a "context" (say 0 - for the host context) b) Processes that are started are started under "context 0". c) You have the option of creating another context (say, context 100) - this will basically enable processes to be isolated from other processes in the system, but still run on top of the booted kernel. (note the kernel does not change, however the processes in context 100 are completely isolated from processes in context 0) d) create more contexts as you want extra virtualization. So basically you are not creating virtual machines, your running processes that are completely isolated from each other. This has the benefit of running each process at host speed (there are no bytecode emulation happening). However it has the dissadvantage that you are stuck with the one kernel. If your looking for a Virtual Machine to run an operating system 100% (kernel and all) then you really need to look at VMWare or others, this is not the project for you. Having said that I use Linux-VServer to run mainly CentOS machines, and a few debian and the odd Fedora distro's, so it really depends on what level of virtualization you need. I also run VMWare Server (on the host, I havn't tried installing it in the guest, but I assume that would be possible) for my windows machines, they run well enough for me in that, including a production Accounting package. > >> (although I suspect that to be more difficult than I suggested >> above). >> >> I would bet you could run Vista on a VMWare Server instance under a >> Fedora guest running a Centos host running Linux-Vserver - but thats >> >> probably not what your after. >> > > > That is NOT my venture on this testing.

Might not be open sourced but free and works well, although the web based interface IMO is no where near as friendly version 1. But certainly usable. Matt.
