+If you installed Xen on &oldreleasename;, the default kernel booted by
+GRUB Legacy was the one providing a Xen hypervisor and dom0 support.
+This behavior has changed with GRUB 2 in &releasename;: the non-Xen kernel
+will boot by default. If you need Xen and expect to boot with it by default,
+there are configuration hints at
+http://wiki.debian.org/Xen#Installationandconfiguration

+Upgrades from &oldreleasename; will not automatically install Xen version 4.0.
+You should install the <systemitem
+role="package">xen-linux-system-2.6-xen-amd64</systemitem> or <systemitem
+role="package">xen-linux-system-2.6-xen-686</systemitem> package to ensure the
+Xen hypervisor and suitable dom0 kernel are installed, and to make future
+upgrades easier.
+</para>
+<para>
+&Releasename;'s 2.6.32 Xen kernel uses pvops instead of the forward-ported
+Xenlinux patch. This means that on &releasename; your domU won't be able
+to use (for example) <filename>sda1</filename> as a device name for its hard
+drive, since this naming scheme is not available under pvops. Instead you
+should use (as a corresponding example) <filename>xvda1</filename>, which is
+compatible with both old and new Xen kernels.
