[Xen-devel] Why does xc_domain_getinfolist() think 256 == 244?
Hi, I am using xc_domain_getinfolist() on x86_32 and have noticed something rather odd. If a dom-u is allocated 256 MB , xc.curmem thinks its 244. We take curmem, and divide it by (1024 * 1024). Any other multiple of 1, 2, 4, 8 (and more) is accurate .. however if curmem == 256, we''ve lost 12 * (1024 * 1024). To reproduce, start 3 mini-os guests with 256 MB of ram, use xc_domain_getinfolist() and see what it says :) I''m working with the current tip of xen-unstable. Yet, xm list reports the memory accurately. I''m puzzled.
