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.
Regards,
