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.
