Hello,

I am sending this email out because I would like to know which are the
free alternatives to Xen. The requirements are: Stability/Performance,
preferably free but it can be commercial (like VMWare and Simics), can
support vast amount of virtualized machines running systems Linux and
Windows (XP/2000/2003) for an x86 computer (like a DELL PowerEdge
2850).

If you need stability, performance and mixed VM environment support including proprietary OS, then vmware esx or gsx are your best bet here so far for a production environment.

From my own experience, gsx runs fine on a dell 2850 (with a w2k3 host), but you'll need a vast amount of memory and the dual CPU configuration if you want multiple VM running at a time.

esx will only provide better performances and other features like VM migration or hot backup. If it's not mandatory, gsx will fit.

Gildas
