Hi all!
I'm Simone Lazzaris and I've been using XenServer in the company I work for since version 4.0. I've choosen XS over VMware for the licensing (VMware licensing is just evil), the hardware support and the architecture, which I find superior.
Over the years I've always found that Citrix was keeping out from XS many features that could be very useful: hyperconverged FS (ceph or gluster), ZFS, automatic upgrades via YUM, etc.
When Citrix then changed the licensing, I was looking for an alternative. I've found XCP very intriguing; I think that if we can build a real community of developers, XCP is going to be the best VM solution for the small-medium business, hands off.
