[Xen-devel] memory calculation mismatch between e820 and guest RAM size

["Li, Xin B" <xin.b.li@xxxxxxxxx>]

In E820, tom of memory is guest memory size we give in the config file,
but guest RAM we allocate is a little bigger than what E820 sets,
because we don't allocate memory for VGA hole from 0xA0000 to 0xBFFFF.
2 ways to fix it:
1) align to current E820 setting, so need to change memory allocation
code in tools.
2) align to guest memory allocation, so need to change e820 setting.
Which one do you prefer?
