Hi folks, Thanks for your advices, I'll take a look on all and post what I conclude on it. Maybe I'm not clear enought, I already had CentOS5.8 Xen on my Hosts, but I'm finding a solution more "enterprise". The HA/Load Balance solution we had are self made, it is much time consuming for our needs. We are searching for something more easy (or self) administering software. This is why we take a look on VMware, Citrix, etc... We'll take a look on OpenStack, RHEV/RHEM, maybe Oracle VM...
