Xen is a paravirtualization system: it requires changes to the guest operating systems, unlike QEMU or VirtualBox which run unmodified systems. NetBSD has built-in support for Xen, while the support for Linux has always been distributed as a set of patches (for reasons unknown to me). This scheme allows for higher performance of the virtual machines. I recommend you to read the "Xen and the Art of Virtualization" paper: www.cl.cam.ac.uk/research/srg/netos/papers/2003-xensosp.pdf
