That's a pity. That said, your decision to not go with KVM due to stability is a bit strange: 1) unless you are using open source Xen, you are presumably going for a commercial solution that would cost you money anyway. Have you thought of asking for commercial support, either from Canonical (since you were using Ubuntu) or from anyone else? 2) I saw now that you were using 3.13. I'm sorry for not having noticed that early, but have you tried upgrading the kernel? There is a known bug with Ivy Bridge EP and hv_vapic, but it's fixed on newer kernels (3.16). If you are not going to pay anyone for support, you probably should have thought about this yourself. If you hadn't thought about it, and you are going for an open source solution (which I hope), you probably should re-evaluate the plan of not paying anyone for support, either a company or someone with enough expertise.
