Hi, First, I am thankful to all who answered my last question (Those are really helpful informations). But this time I need to know How Xen exactly starts the Dom0''s kernel. How it allocate the memory and cpu[s] to Dom0''s kernel for the first time (StartOfDay). Briefly, In which source files these thing happens. I know that Linux itself can handle hotplugable cpu''s and memories but is it possible for Xen to provide this facility to the running Dom0 kernel (Linux). -- Best Regards, Mohamd M.
