The original code is wrong because: * claim mode wants to know the total number of pages needed while original code provides the additional number of pages needed. * if pod is enabled memory will already be allocated by the time we try to claim memory. So the fix would be: * move claim mode before actual memory allocation. * pass the right number of pages to hypervisor. The "right number of pages" should be number of pages of target memory minus VGA_HOLE_SIZE, regardless of whether PoD is enabled. This fixes bug #32.
