I have used VMware for YEARS (GSX, ESXi 4 now 5). Have always known of Xen but really never bothered. Of course, Xen lost favor with FOSS (Linus, et. al.) when Citrix picked up Xensource a few years back. Thus, the new focus on KVM (which is a promising hypervisor in its own right but (to me) the management layer ain't there yet, even with RHEL6 - still looking forward to it though). But Xen remains huge with cloud players like Amazon. So, when I saw that Xenserver had a free version, I decided to play with it. It was nice but restricted like the free ESXi 5. But I caught sight of Xen Cloud Platform (XCP) which repackaged free Xenserver but with many enterprise features rolled back in. With the recent 1.6 release of XCP, some pretty darn important enterprise stuff was included. In particular Xenmotion grabbed my attention (since the equiv in VMware, vMotion, comes only with the $5K+ packaging). I know all this has always been at the pure Xen level, but I have a lot on my plate, and need customers to be self-sufficient, so a good management layer like XenCenter (or vSphere) is a must. Correct me please, but in practice, XCP 1.6 is doing a pretty damn good job for me so far. I have one client with 20 VDIs on an XCP 1.6 server and it is, so far, doing well. Am I missing something? And, Citrix seems to be doing a decent job of trying to be a good FOSS corpizen, so is there some reason to spend $5K+ for VMware Essentials Plus over free XCP? I know there are subtle differences in the way ESXi and Xen hypervisors implement virtualization, etc. And, some scenarios (like high I/O of heavy RDBMS apps) will kill VMWare the same as Xen too. But if XCP/Xen get the job done for $0K (both not withstanding my $ time), is there some reason I should only do VMware? I think Citrix+Xenserver/Xen/KVM/and even Hyper-V 3 (yeah, I know, M$) are going to prove to be game changers for the market dominance VMware has enjoyed up til now (in cost-benefit if nothing else).
