+If 'running in Xen' means 'running as guest', you don't need any special 
+kernel for hardware virtualisation, and just a kernel with Xen support 
+for paravirtualisation. The dom0 support is only needed for the xen 
+host. Which means the installer kernel itself should have xen support to 
+be runnable in any context.
+
+By the way, kernel-xen-pvops isn't needed anymore, and could be safely 
+dropped AFAIK.
