release notes virt passage seems overly pessimistic

[Keqin Hong]

I agree with Robert, as I could only use VirtualBox or QEMU on my
laptop without Intel-vt. But on the other hand, I think KVM will be
ideal for new machines with HW virt support especially for data
centers. It's fast, mainstream and becoming mature.
Hope Xen dom0 could be included as an additional choice for desktop users.
