The smarter way is to keep the kernel & initrd / RPM installed inside the
guest OS itself.
This is not acceptable, since the guests are basically tar files that are unaware of the
existance of xen. They are pre-created ostemplates from
jailtime.org and it is the duty of
the host to provide transparent virtualization. Also just think of the scale. It is always
better to get ONE host working properly rather than to makes sure that 200 guest
ostemplates are all kept in sync.
thanks.
