I need to know if there is any formula(e) to compute the MAXIMUM
amount of memory I can allocate to host a Domain 0 hosted on
Linux-2.6.11, presuming I don't intend to run any guest domains on the

Consider that I have 512M of RAM available.How much I 'll be able to
exploit with Xen Domain 0.

I see that I can't use the full 507012 kB which is otherwise available
to a standard Linux-2.6/2.4.
