No ! vserver is another virtualization technologie, sort of chroot enhanced. You can have vserver without Xen (linux-image-vserver* packages). This kernel permit to use both XEN, and vserver, because you can have several vservers in one xen virtual server. It's far more light than XEN when you have several Linux virtual servers of the same distribution. You can imagine a server with two Xen virtual servers, one with Windows and One with Debian+vserver. This Debian can itself hosts 3, 4... virtual Debian Linux servers.
