You don't have to purge anything.  If you have an existing Xen guest, 
you can work with it as is; no need to install grub if you dont want 
to.  For new installs, of course it is easier to fire up the native 
installer which does everything for you.

Things like updating the guest kernel and initrd are usually much easier 
if the kernel is contained within the guest disk image.  Similarly, 
copying an image or backing it up is simpler if you don't have to worry 
about the kernel.

Guest performance will be lower, but just for the test.  The -no-kvm 
option is very useful in determining whether the problem is in the 
kernel or userspace.
