Well, what I concern is about the Xen modified kernel stuffs (e.g.
/lib/modules/2.6.18-xen), i.e. if my two Xen hosts are running 2
different versions, will there be any problem if I overwrite the Xen
stfuffs ? (e.g. lead to performance/stability problem etc).

I rather not too worry about my data, as they are mainly static
contents (even MySQL is 100% read only, so I don't care the
consistency though).
